Case study of the hybrid vehicle

Case study of the hybrid vehicle Alternative fuels are fuel that other than conventional fuel (fossil fuels or nuclear materials) used in energy-generated combustion such as biodiesel, hydrogen fuel, chemically stored electricity (hybrid), biomass and so on. Now there are many type of alternative transportation fuel in market. One of it is found out to be the hydrogen; however it is too expensive. So, instead, the automobile industry is embracing the idea of hybrid concept which switches between petrol and electricity. A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. Normally, such vehicles are powered by a combination of 2 energy sources: electricity and conventional fuel which mean combine a conventional ground propulsion system with an on-board rechargeable energy storage system (RESS) to achieve better fuel economy in automobiles. However, conventional vehicle like a battery electric vehicle without being hampered by range from a charging unit uses batteries charged by an external source. The different propulsion power systems may have common subsystems or components. The major advantage of hybrid car over electric car is that the battery is recharge not from an external socket but from the vehicles gas-powered generator and from kinetic energy generated when the brakes are applied. The hybrid vehicle able to achieve greater fuel efficiency and lower emission than conventional internal combustion engine vehicle (ICEV) resulting in less emission being generated. So, it contributes a lot to the environmental concern, as it reduces green house gasses, carbon emission. Besides, this high-tech low-emission vehicle can get over 60 miles/gallon (mpg), offering significant saving on fuel cost. In short, it is a better transportation choice for the sustainable development in future. Type of hybrid vehicle The electrical machine is designed to handle transient power variations and helps the engine to operate more constantly such that higher efficiency and lower tailpipe emissions can achieve. Many type of hybrid system exist in the engineering conceptual framework. Now many of them applied in the vehicle engine system. The following listed down few types of hybrid vehicle: 1. Series hybrid vehicles In a series hybrid vehicle, the internal combustion engine is not directly connected to the drive train at all; rather it powers an electrical generator instead. The advantage of this type of hybrid is the flexibility afforded by the lack of a mechanical link between the internal combustion engine and the wheels. Whilst, weakness of this system is that it require separate motor and generator portions which can be combined in some parallel hybrid engines; the combined efficiency of the motor and generator will be lower than that of a conventional transmission thereby offsetting the efficiency gains that might otherwise be realized. 2. Parallel Hybrid In a parallel hybrid the electric motor and the internal combustion engine are installed so that they can both individually or together power the vehicle (Wikipedia, 2010). They can be sub classified on the bases of the ratio of contribution to the motive power of the different component or portion. Most designs combine a large electrical generator and a motor into one unit often situated between the internal combustion engine and the transmission replacing both the conventional starter motor and the alternator (Michael). 3. Hybrid electric-petroleum vehicles A petroleum-electric hybrid normally uses internal combustion engines (gasoline or Diesel engines, powered by a variety of fuels) and electric batteries to power electric motors. Most designs combine a large electrical generator and a motor into one unit often situated between the internal combustion engine and the transmission replacing both the conventional starter motor and the alternator. Toyota Prius, Toyota Camry Hybrid and Honda civic hybrid has this type of engines system. 4. Continuously outboard recharged electric vehicle (COREV) This is a system that enables the battery of vehicle to recharge while the user drives. When the Battery Electric vehicle (BEV) establishes contact with an electrified rail, plate or overhead wires on the highway via an attached conducting wheel, it will trigger recharging mechanism. The BEVs batteries are recharged by this process on the highway and can then be used normally on other roads until the battery is discharged. 5. Hybrid fuel (dual mode) Hybrid fuel vehicle is known as dual mode hybrid system which uses 2 or more different devices for propulsion, meaning the engine had the ability to use another fuel source to power the system except the electricity. This system contains not only 1 fuel and electricity but also another 1 or 2 back-up fuel in the system. There are many types of hybrid fuel used in different vehicle including dual mode bus, flexible-fuel vehicles, bi-fuel vehicle, modified fuel vehicle and motorized bicycle. The fuel used in this system range from hydrocarbon chained diesel (petroleum, ethanol, natural gas, gasoline and biobutanol) to vegetable oil. 6. Fluid power hybrid Hydraulic and pneumatic hybrid vehicles use an engine to charge a pressure accumulator to drive the wheels via hydraulic or pneumatic (i.e. compressed air) drive units. The energy recovery rate is higher and therefore the system is more efficient than battery charged hybrids, demonstrating a 60% to 70% increase in energy economy in EPA testing (Bruno, 2006). Under tests done by the EPA, a hydraulic hybrid Ford Expedition returned 32 miles per US gallon (7.4 L/100 km; 38 mpg-imp) City, and 22 miles per US gallon (11 L/100 km; 26 mpg-imp) highway. UPS currently has two trucks in service with this technology. (Alex, L, 2006). The system has faster and more efficient charge/discharge cycling and is cheaper than gas-electric hybrids, the accumulator size dictates total energy storage capacity and requires more space than a battery. (wikipedia, 2009) Degree of Hybridization A. Full Hybrid Electric Vehicles A full hybrid vehicle is the one that can run on just the engine, just the batteries or a combination of both. The Prius and Escape Hybrids are examples of this because both cars can be moved forward on battery alone. A large, high capacity battery pack is needed for battery only operation. These vehicles have a split power path that allows more flexibility in the drive train. To balance the forces from each portion, the vehicles use a differential style linkage between the engine and the motor connected to the head end of the transmission. B. Assist Hybrid Electric Vehicles This type of hybrids use the engine for primary power, with a torque boosting electric motor connected to the conventional power train. The electric motor is essentially a very large motor which operates not only when the engine needs to be turned over, but also when the driver steps throttle pedal and require extra power. Assist hybrids differ fundamentally from full hybrids in that they cannot run on electric power alone. However since the amount of power needed is very small, the size of the battery system is relatively small. C. Mild Hybrid Electric Vehicles These are conventional vehicles with oversized starter motors; allowing the engine to be turned off whenever the car is coasting, braking or stopped, yet restart quickly and cleanly. Accessories can continue to run on electrical power while the engine is off, and the motor is used for regenerative braking to recapture energy. The motor is used to run up the engine to operating speed before injecting any fuel. Many people do not consider these to be hybrids at all, and they do not achieve the fuel economy of full hybrid models. Case study on the Proton EMAS The first concept car, Proton EMAS, which is planned to be in production line soon (might be in 2011) makes Proton leading in front of others with the most high tech compact concept car design. This superb Electric Hybrid Car from Proton which has been designed by Italdesign and Engine Technology by Lotus and soon will be produced by Proton, local car manufacturer. The name, Emas, meaning gold in Malay, is the acronym for Eco Mobility Advanced Solutions. At the eightieth edition of the Geneva International Motor show (4-14 March 2010), Italdesign Giugiaro is introducing Emas, a family of low environmental impact cars that is set to revolutionize traditional segmentation in the car market. The design, created with the Malaysian manufacturer PROTON is based on a plug-in hybrid drive system designed with Lotus Engineering and was developed with the aim of optimizing the available on-board space and car access ergonomics. The prototype of Proton EMAS engine have different configuration that it might be conventional, hybrid with petrol engine, hybrid with natural gas engine or fully electric. Problem Statement: Internal Combustion Engine (ICE) vehicles emit carbon dioxide, hydrocarbon, sulphur oxides, carbon monoxide and hydrocarbon through their tailpipes. These gases result in global warming through green house gas effects and pollution which are harmful to both environment and lives. By the way, the prices of fossil fuels keep rising from time to time. There is a growing scientific consensus that increasing levels of greenhouse gas emissions are changing the earths climate. Oil prices continue to sky rocket while tougher regulations and policies on permitted exhaust gases are being instituted in major cities of the world. These and some other related issues are compelling vehicle manufacturers to come up with fuel efficient vehicles. These types of vehicles are known as hybrid electric vehicles. Nowadays, the prices of petrol are continuously increased and this non-renewable energy is in critical level of shortages. The American petroleum institute estimated in 1999, the world will be completely run out of petroleum by 2062 to 2094. So, now more and more automobile industries are introduced many type of environmental friendly and petrol efficient car to reduced the usage of petrol and diesel. The significant of hybrid vehicle are increasingly important to the environmental sustainability. The trend of owning hybrid vehicle is very popular in western country since 1800s. However, the awareness of the green house effect to the climate change is still low among the Malaysian. Therefore, the hybrid vehicles until now still can not manage to gain attention of public and high market demand in Malaysia. Hybrid concept car had been introduced many years ago by Toyota Prius in Malaysia. But due to various factors, might be the expensive prices and technological problems cause the demand for this type of car is still low. Now, Proton launched a new series of Proton EMAS that follow hybrid concept. Will it be the next new generation wave that changes the Malaysian mindset in owning hybrid car? Since, Proton is the Malaysian owned local car manufacture, the prices of the hybrid car may lower compare to the Toyota Prius. The import tax and excise tax that applied on the stakeholder will considerably low compare to the Toyota Prius. So, will it be a better choice for Malaysian to have an environmental friendly car? Research question: 1, Is the introduction of the hybrid concept car to Malaysian bring a success. 2. How the hybrid concept in vehicle impact the environment and sustainable development in future. 2. What are the competitive advantages of the hybrid vehicle that difference from the other alternative fuels? Research Objective: 1. To investigate the respondents of society/public to the hybrid vehicle that had introduced. 2. To survey the effectiveness of the hybrid vehicle to the environmental concern. 3. To find out the way hybrid vehicle function correspondent to the sustainable development by comparing to other alternative fuels. Chapter 2: Literature Review 1) Market analysis on Hybrid vehicle 1. Assessing current vehicle performance and simulating the performance of hydrogen and hybrid cars Bent Sorensen, Roskilde University, Institute for Nature, Systems and Models; Energy, Environment and Climate group, Universitetsvej 1, DK-4000 Roskilde, Denmark This journal basically presented simulation study of the efficiency in transforming the energy input into transport works. The insight obtained in measure is compare with the result applying performance of fuel cell, electric vehicles and hybrid between the two. The author stated that: Some people are willing to spend more money on an inefficient car than on the most efficient ones offered in the marketplace, for reasons of biased advertising and the archaic notion that less efficient cars rank higher as status symbols. (Ben Sorensen, 2006). So, it means that the authors viewpoint is clear to panelize the market demand on the hybrid vehicle in future. 2. In the research of heather and Lester, 2002, they compare the 2nd generation of the 1st commercial hybrid electric vehicle (HEV) the Toyota Prius, to the conventional internal combustion engine (ICE), the Toyota Corolla. They found out that the more expensive and complicated Prius has lower pollution and CO2 gas emission and better fuel economy than the Corolla. Besides, the Prius is not cost-effective in improving fuel economy or lowering emission. For the Prius to be more attractive, they suggest that the price of gasoline should be lower about 3 times than the present and the social value of abating tailpipe emission would have to be 14 times greater than conventional value. So, they concluded that the hybrid will not have significant sales unless fuel price raise several-ford or regulation mandated. AGREE 3. Evaluation of electric motor and gasoline engine hybrid car using solar cells K. Sasaki*, M. Yokota, H. Nagayoshi, K. Kamisako In this paper, the utility of a hybrid car equipped with a gasoline engine, an electric motor and solar cells was evaluated. Though the capacities of the electric motor and batteries are half the size compared with conventional electric vehicles, it was confirmed that this car is sufficient for practical use. The total electric energy consumed in a day can be supplied by a 1.6 kW solar array which can be easily set on the roofs of common houses or parking lots. So, they concluded as such a hybrid car must contribute to depression of the air pollution in urban areas. (K. Sasaki, 1997) 4. Does the hybrid Toyota Prius lead to rebound effects? Analysis of size and number of cars previously owned by Swiss Prius buyers Peter de Haan *, Michel G. Mueller, Anja Peters Peter D.H et al (2006) in his analysis on the hybrid rebound effect found that the Toyota Prius 2 is indeed a product that effectively combines fuel efficiency and the satisfaction of consumer needs, and is successful in replacing daily-use vehicles and becoming the most used car in a household. Besides, they also confirm that hybrid vehicles like the Toyota Prius indeed have a positive effect on total CO2 emissions from road transport, and that rebound effects are not yet in sight. Then, they think that financial support for the purchase of hybrid vehicles seems to be a possible and valid environmental policy. Further progress in fuel-efficiency gains using hybrid powertrains is to be expected also. 2) Hybrid function in lowering emission 1. An Overview of Hybrid Electric Vehicle Technology, Michael O. Omoigui In the article, an overview of hybrid electric vehicle technology, Michael listed down variety of weakness and benefits of the hybrid vehicle to sustainable future. He also explained in details how the hybrid functions to lower emission and fuel economy. The article encapsulates factors that necessitate the development of hybrid electric vehicles, classifications of hybrid electric vehicles based on the arrangement of the internal combustion engine and the electric motor for traction. The types of batteries required and the use of power electronic converters for effective power processing and utilization in hybrid electric vehicle drive is covered. 2. Solutions reducing green house emission from US transportation David L. Greene, OAK RIDGE NATIONAL LABORATORY, Andreas Schafer, MASSACHUSETTS INSTITUTE OF TECHNOLOGY In this book, authors make the comparison between difference types of alternative fuel in term of reducing green house gases (GHG). The findings clearly showed that only hydrogen and electricity is a better alternative fuel to replaced fossil fuel in the next 15 years beyond. Although other alternative fuels could play a transition role, it is questionable whether the associated high investments and limited GHG emission reduction potential would justify large-scale shifts to any of these fuels. 3. Environmental Assessment of Plug-In Hybrid Electric Vehicles Volume 1: Nationwide Greenhouse Gas Emissions, report, July 2007 In the report, the EPRI team aims to examine the greenhouse gas emissions and air quality impacts of plug-in hybrid electric vehicles (PHEV). The purpose of the program is to evaluate the nationwide environmental impacts of potentially large numbers of PHEVs over a time period of 2010 to 2050. The analysis showed the PHEVs adoption results in significant reduction in the consumption of petroleum fuels. They stated that in the Medium PHEV case, fuel savings were equivalent to 3.7 million barrels per day by 2050. 4. Government legislations on hybrid transportation 5. Malaysia Master Tax Guide 2009, 26th ed,, Veerinderjeet, S. Teoh B.K. 6. Policy instruments for environmental and natural resource management. Thomas Sterner Malaysian tax guide information stated that for application received by the ministry of finance from 30 August 2008 to 31 December 2010, franchise holder of hybrid car are given 100% exemption of import duty and 50% of exemption of excise duty for the new completely build-up (CBU) hybrid car subjected to certain criteria and condition. (Veerinderjeet, S. Teoh B.K., 2009). In condition, country like United State tightening standard of emission rate by Clean Air Act. By the way, in 1990, California Air Resources Board (CARB) adopted a visionary scheme to progressively reduce emission requirement. This government reinforcement had successfully forced manufactures to sell vehicle that fulfill environmental criteria. (Thomas S.) Chapter 3: Methodology This research will conduct by using secondary sources collection, questionnaires and direct interviews to public and suppliers. 3.1 Secondary sources collection The main method of gathering information for this research is by collecting and analyzing secondary sources. Library searching is one of the ways to look for the books, journals, articles, media and press released, and so on. Besides, website (official website of Proton) and online databases (science world, science direct) also will be use to search for updated data. 3.2 Questionnaires Another way to find information for this research will be by surveying on the public viewpoint on the hybrid vehicle in various terms includes the performance, eco-friendly characteristics, cost effectiveness, petrol saving and so on. This will be done by giving questionnaires to the 100 selected people in UM includes students, lecturers, and staff. Then, the answer will be the quantitative data after analyzed and computed into figures and data. 3.3 Interview Interview will be done in 2 alternative ways to gather public opinions on the hybrid vehicle that had introduced. 1 is done to the selected society/public that play role to impact the car ownership decision. By interviewing, the factors that influent drivers to own a car will be found. So, the market demand for the hybrid car and the viewpoint of the public to the hybrid car will also revise. Then, another way of interview will be done with the Proton manufacturer, Proton Holding Sdn Bhd to get 1st hand information on the Proton EMAS car. However, this can only carry out with approval from the Proton behalf and act as a supportive way to the other research methods. By comparing both the viewpoints of the supplier and public may lead to different decision making on choice of car to be own in future. Research Limitation The limitation of the research will be focus mostly on the Malaysian viewpoint about the new concept car, Proton EMAS. A lot of problem will be face along the time doing a research. One of the obstacles for me to do this research is difficulty in finding materials about the hybrid vehicle in Malaysia. Since the concept are still new and strange to Malaysian society. So, not much of the information I got regarding this 1st concept car in Malaysia. The way I do is I try to substrate some news from the press or website. Moreover, the new Proton EMAS now still in stage of prototype and not yet can be found in the market in Malaysia. Society are also no much awareness to this type of car will be launched soon locally. So it is quite problematic to do research on this topic. Besides, the knowledge of how the vehicles hybrid system to function in reducing emission is rare and unknown for the Malaysian. That is why the question should be set according to the society common known without using heavy word or scientific term in questionnaires. Due to the difficulty in transportation problem, the survey will only conduct in University of Malaya. The population includes student, lecturers, and staffs which act as a sample of actual society in Malaysia. However, the result will only show a population size of around 100 people in UM which may be bias toward the actual condition. 1. http://green.autoblog.com/2006/06/15/capturing-the-power-of-hydraulics, Bruno V, 15 June 2006 2. http://www.autoblog.com/2006/06/26/epa-unveils-hydraulic-hybrid-ups-delivery-truck , Alex, L., 26 June 2006 Colour file location Red hybrid technology Purple wikipedia Yellow toyota vs corolla Brown hybrid performance Pink solar hybrid cell

Medication vs. Natural Treatment for ADHD Essay

Attention Deficit Hyperactivity Disorder (also known as ADHD) is an increasing struggle among children in today’s society that affects them at home, in their social lives and academically. Many people think that all-natural treatments are the only way to help children who struggle with ADHD; however, despite the controversy over using medication with possible side effects, Adderall can be a helpful tool in the battle against ADHD. ADHD is a chronic neurological condition that affects millions of children and can often carry into adulthood. Signs and symptoms of ADHD may include trouble staying focused, trouble listening, difficulty completing tasks, fidgets and squirms and tends to be forgetful. Clearly, having these symptoms can make it difficult for a child to succeed in school and in other activities as well. (Mayo Clinic Staff, 2011) Many people believe that medication will affect a child negatively but medications are used every day to help with medical issues. For instance, if your child had diabetes would you hesitate to treat the disease with medication? Obviously, parents would do what was needed to help their child overcome this disease. In the same way, we need to be open to the idea of using medication to treat ADHD. There are many treatments available to help in the battle against ADHD. Medication is a controversial subject when it comes to treating any disorder; however, when medicine is used under a doctor’s supervision and distributed correctly, it can have a positive effect on the problem. When medication is taken, it enters the bloodstream and the key ingredients begin to stimulate the brains production of norepinephrine and dopamine which improves a person’s concentration and alertness. People with ADHD also tend to suffer from high blood pressure and rapid heartbeat but when medication is taken, it can help to get these problems under control and return the person’s system back to a normal state. (Nall) Another method of treatment that is widely used is natural treatment such as dieting and counseling. Some people may see positive results with Natural Treatments but for some children, medication is the only way to get their symptoms under control. Some experts believe that ADHD can be caused by food allergies and that by using the elimination diet, you can locate the allergy and treat the symptoms. In an elimination diet, you remove foods one at a time that your doctor believes may be causing the symptoms. Gradually, you begin re-introducing these foods back into your diet and when your symptoms return, then a diagnosis can be confirmed. (â€Å"Elimination diet and,† 2011) There has also been much thought put into the effect that processed sugar has on ADHD and research shows that it can have an effect on children’s activity levels. Nutritionists suggest that adding high fiber foods such as berries and other fruits, whole grains and oatmeal to your child’s diet that it can help manage their glucose levels and aid in the treatment of ADHD. These diets may be useful in the battle against ADHD but you can’t guarantee that this will help with the symptoms. There are so many processed foods available in the market today that it is very hard to keep sugar and other processed ingredients out of your diet. In order to follow through on the diet, one must make their child’s food and snacks and keep up on a very strict regime to make sure that they do not consume the â€Å"culprit† foods. Not every person can keep up on a diet to this extreme and that is when medication is available to help keep the symptoms under control. Counseling such as behavioral training can be an effective treatment for ADHD. Also available is learning behavior management that can be an essential part of any ADHD treatment. There are three levels of ADHD behavioral training that they focus on: * Parent training * Classroom behavior modification * Special education placement Although behavioral training management can be effective, according to WebMD, most experts agree that combining behavior management along with medication treatment can be the most effective treatment plan. One medication that has been used to treat ADHD is Adderall (Dextroamphetamine-amphetamine). Adderall was approved for treatment by the FDA in 1996 and has become a very popular choice in treatment. Adderall is considered a stimulant medication and according to The Mayo Clinic it appears to boost and balance levels of brain chemicals called neurotransmitters. Adderall helps to improve symptoms such as attention problems, impulsivity and hyperactivity. (Mayo Clinic Staff, 2011) Adderall has many possible side effects that can cause concern, but if under a doctor’s supervision it is considered a safe treatment. (Monson & Schoenstadt, 2008) When taking treatments into consideration, one must figure out if the side effects of the medicine are a small price to pay to conquer the annoying and life interrupting symptoms of ADHD. There are many benefits to both methods of treatment. When using the natural methods such as diet and counseling, you do not have the possibility of side effects like you do with the medication but for more severe forms of ADHD, you do not see as high of an improvement rate. Although there are the chances of side effects when taking Adderall, it does have more of a calming effect on the patient. The benefits of using Adderall include being able to focus, sit still, complete schoolwork and help in many other areas that ADHD affects. I know that with my own personal experience as we have walked through the battle of ADHD with my son, it is difficult to find the correct treatment plan that needs to be followed. We tried diets and counseling but could not seem to get a grasp on his symptoms. After being against medication for such a long time, we finally sat down with our pediatrician and explored all options available to us. Our pediatrician explained to us that when people have cancer, they need treatments of chemotherapy and or radiation to kill the disease. In my opinion, Adderall is the â€Å"chemotherapy and radiation† for ADHD. We tried for many years to help our son succeed in school and it wasn’t until we started his treatment of Adderall twice a day that we started to see improvement. Adderall is not an â€Å"instant† fix but given time, it is effective. Our son is now going into high school and not only does he have passing grades, but we no longer get calls from the teachers because he is unable to sit still and pay attention. Anytime medications are used in treatment plans, there is always a possibility of side effects. By going about treatment with medication in the proper manner and following your doctor’s advice, Adderall and other medications can be a very useful tool in gaining control of your child’s ADHD. I do believe that natural treatments are always the best option and should be considered first, but when these treatments do not help solve the issue then you need to consider other options. When your child suffers from ADHD and it affects all areas of their lives, you need to be open to whatever options are available to help you get the situation under control. By using Adderall and natural treatments such as diet and counseling together, you can get control back of your child’s behavior and see many benefits in the home, social setting and school settings.

The Devastating Effects of Arson Essay - 2651 Words

Arson is â€Å"any willful or malicious burning or attempt to burn, with or without intent to defraud, a dwelling house, public building, motor vehicle or aircraft, [or] personal property of another† (Bartol Bartol, 2011. P 463). Arson comes in many forms – juveniles vandalizing property, businesses trying to collect insurance money, and murderers covering up their crimes are just a few of the examples arson investigators deal with. The reasons why arson is committed and the psychology behind arson are as diverse as the crime itself. There is no one perfect psychological profile of an arsonist. Young, old, educated, illiterate, sane, insane, rich and poor all can become arsonists. With such a wide range of suspect characteristics,†¦show more content†¦A small percentage arsonists are driven by a mental condition known as pyromania, which is an irresistible urge to set fires combined with an intense fascination for flames (Bartol Bartol). These fire sett ers claim they have no control over their fire setting impulses. The Uniform Crime Report (UCR) published by the FBI gives a little better look of the profile of an arsonist, though not much. Only those fires that are determined to be deliberately set are included in the UCR, suspicious fires are not. In 2009, Motor vehicles and other mobile property accounted for 28.4% of arsons, 27.1% were arsons that involved crops, timber, fences and other such types of property, and the remaining 44.5% of arsons were those involving structures – residential, commercial and public. With all of the different reasons for setting arson fires, as well as the large variance in profiles of arsonists, investigating them can be difficult. This difficulty is compounded by the amount of evidence than can be destroyed by the act of arson. Arson investigators must begin by trying to find the point of origin; a task that can be made very difficult by tossing aside the debris and damaged items while the fire is being fought (Swanson, et al. 2006). If arson is suspected, the point of origin can be a deciding factor in declaring a fire intentional, especially if the fire began in the center of the roomShow MoreRelatedFighting Fire With Fire Essay1742 Words   |  7 PagesDue to this new law, the southwest saw something unexpected.
