Hybrid cars: Corrected Abstract: A hybrid car, also known as an HEV or hybrid electric vehicle, is an automobile that is powered by two sources; an internal combustion engine, and an electric motor. HEV’s need plugs, as they are amply charged by the movement of the wheels and storing the kinetic energy that is generated through a process called regenerative braking. cars have been accepted as a solution to the current pollution problems that we face, as they offer lower emissions than gasoline automobiles. Some hybrid cars produces around 90% less pollutants than regular cars. With cars with this system, a hybrid car can cross longer distances than normal ones with less use of gasoline. They can get up to 55-60 mpg in city driving, while a typical SUV might travel just 15-20 mpg. Also there are 2 types of cars: the first type is the series, and the second type is called the parallels First draft: Hybrid electric vehicle A hybrid electric vehicle (HEV) is a vehicle which combines a conventional propulsion system with an on-board rechargeable energy storage system (RESS) to achieve better fuel economy than a conventional vehicle without being hampered by range from a charging unit like a battery electric vehicle (BEV), which uses batteries charged by an external source.

Regular HEVs most commonly use an internal combustion engine (ICE) in tandem with electric motors to power their propulsion system. Modern mass-produced HEVs prolong the charge on their batteries by capturing kinetic energy via regenerative braking, and some HEVs can use the combustion engine to generate electricity by spinning an electrical generator to either recharge the battery or directly feed power to an electric motor that drives the vehicle. Many HEVs reduce idle emissions by shutting down the ICE at idle and restarting it when needed. An HEVs engine is smaller and may be run at various speeds, providing more efficiency. HEVs became widely available to the public in the late 1990s. HEVs are viewed by some automakers as a core segment of the future automotive market. Technology The varieties of hybrid electric designs can be differentiated by the structure of the hybrid vehicle drivetrain, the fuel type, and the mode of operation. In 2007, several automobile manufacturers announced that future vehicles will use aspects of hybrid electric technology to reduce fuel consumption without the use of the hybrid drivetrain. Regenerative braking can be used to recapture energy and stored to power electrical accessories, such as air conditioning. Shutting down the engine at idle can also be used to reduce fuel consumption and reduce emissions without the addition of a hybrid drivetrain. In both cases, some of the advantages of hybrid electric technology are gained while additional cost and weight may be limited to the addition of larger batteries and starter motors. There is no standard terminology for such vehicles. The 2000s saw development of plug-in hybrid electric vehicles (PHEVs), which can be recharged from the electrical power grid and do not require conventional fuel for short trips. Engines and fuel sources: Gasoline engines are used in most hybrid electric designs, and will likely remain dominant for the foreseeable future. While petroleum-derived gasoline is the primary fuel, it is possible to mix in varying levels of ethanol created from renewable energy sources. Like most modern ICE-powered vehicles, HEVs can typically use up to about 15% bioethanol. Manufacturers may move to flexible fuel engines, which would increase allowable ratios, but no plans are in place at present. Diesel Diesel-electric HEVs use a diesel engine for power generation. Diesels have advantages when delivering constant power for long periods of time, suffering less wear while operating at higher efficiency. The diesel engines high torque, combined with hybrid technology, may offer substantially improved mileage. Most diesel vehicles can use 100% pure biofuels (biodiesel), so they can use but do not need petroleum at all for fuel (although mixes of biofuel and petroleum are more common, and petroleum may be needed for lubrication). If diesel-electric HEVs were in use, this benefit would likely also apply. Diesel-electric hybrid drivetrains have begun to appear in commercial vehicles (particularly buses); as of 2007, no light duty diesel-electric hybrid passenger cars are currently available, although prototypes exist. So far, production diesel-electric engines have mostly just appeared in mass transit buses. Design considerations In some cases, manufacturers are producing HEVs that use the added energy provided by the hybrid systems to give vehicles a power boost, rather than significantly improved fuel efficiency compared to their traditional counterparts. The trade-off between added performance and improved fuel efficiency is partly controlled by the software within the hybrid system and partly the result of the engine, battery and motor size. In the future, manufacturers may provide HEV owners with the ability to partially control this balance (fuel efficiency vs. added performance) as they wish, through a user-controlled setting. Electric vehicle conversion One can buy a stock hybrid or convert a stock petroleum car to a hybrid electric vehicle using an aftermarket hybrid kit . Benefits of the hybrid electric design include: Fuel consumption Current HEVs reduce petroleum consumption (compared to otherwise similar conventional vehicles) primarily by using three mechanisms: a) Reducing wasted energy during idle/low output, generally by turning the ICE off; b) Recapturing waste energy. c) Reducing the size and power of the ICE, and hence inefficiencies from under-utilization, by using the added power from the electric motor to compensate for the loss in peak power output from the smaller ICE. Any combination of these three primary hybrid advantages may be used in different vehicles to realize different fuel usage, power, emissions, weight and cost profiles. The ICE in an HEV can be smaller, lighter, and more efficient than the one in a conventional vehicle, because the combustion engine can be sized for slightly above average power demand rather than peak power demand. The drive system in a vehicle is required to operate over a range of speed and power, but an ICE has its highest efficiency is in a narrow range of operation, making conventional vehicles inefficient. In contrast, in most HEV designs, the ICE operates closer to its range of highest efficiency more of the time. The power curve of electric motors is better suited to variable speeds and can provide substantially greater torque at low speeds compared with internal-combustion engines. The greater fuel economy of HEVs has implication for reduced petroleum consumption and vehicle air pollution emissions worldwide. Reduced wear on the gasoline engine, particularly from idling with no load. Reduced wear on brakes from the regenerative braking system use. Theres no definitive word on replacement costs of the batteries because they are almost never replaced. Environmental impact Reduced noise emissions resulting from substantial use of the electric motor at idling and low speeds, leading to roadway noise reduction,in comparison to conventional gasoline or diesel powered engine vehicles, resulting in beneficial noise health effects (although road noise from tires and wind, the loudest noises at highway speeds from the interior of most vehicles, are not affected by the hybrid design alone). Hybrid Cars free essay sample The government needs to continue to offer incentives to new buyers of hybrid vehicles to offset the higher cost of these vehicles relative to their non-hybrid counterparts. Hybrid cars and other eco-friendly products are vital to the survival of the earth and the United States and the rest of the world must continue to regulate the emissions without hurting the economy. Demand for the Hybrid Vehicles Demand for the hybrid vehicles in the United States has increased since the introduction in the U. S. market in 2000. The first hybrid car was introduced in Japan in 1997 by Toyota Prius. Three years later, Honda introduced the first hybrid car Honda Insight into the U. S. market. By 2008, other car manufactures entered the hybrid market including Ford, GM, Honda and Nissan. Today, they are four main types of electric cars available on the market which include hybrid electric vehicles, plug-in hybrid electric vehicles, extended-range electric vehicle and battery electric vehicles.

In 2003 and 2004 Toyota made100,000 Prius and in 2007 they made 200,000 hybrid cars. In 2012 Toyota Prius Plug-in hybrid is the third fastest-selling car in U. S. Toyota was successful because of strong branding and unique design of Prius. The hybrid vehicles are solution to energy security and environmental protection. These vehicles reduce CO2 emission and air pollution. They combine power from both gasoline engine and an electric motor that runs off the electricity from a rechargeable battery. 1 Hybrid cars produce less pollution because the combination of battery power and internal combustion decrease the emission of carbon dioxide and other harmful gases. Electric motors use no energy during idle and use less than gas motors at low speeds. Hybrid cars have a regenerative braking, stop- start system, low-rolling re sistance tires and power conservative hardware. 1 All these features allow the hybrid cars to recycle energy. Energy produced by hybrid is recycled from brakes and used in acceleration. Hybrid car can save money on gas especially in city driving because stop and go driving helps hybrids recharge by capturing the energy generated during braking. Hybrid cars are in high demand but they are not easy to find and some car dealerships struggle to meet demand. Recent earthquake in Japan made it even more difficult for hybrid cars supplies because the best-selling hybrid cars in the United States Toyota Prius is made exclusively in Japan.

Global warming is a serious problem that can cause major issues such as the melting of polar ice caps and a rise in sea level. Every car produces emissions while being made and while driving on the road. There are many governments regulations placed on industries to reduce the amount of emissions released into atmosphere. Once the hybrid cars become more popular and affordable among consumers they can help reduce automobile emission. When people buy cars they take into consideration many things. They look into price, performance, safety and expenditure on gasoline which is determined by the vehicle’s fuel efficiency. Hybrid cars are expected to reduce the cost of fuel by recharging batteries from electrical outlets. Many buyers today are also interested into saving our planet and there is a growing demand to buy hybrid vehicles. Hybrid cars offer many green advantages. In large cities were pollution is high, they produce very little emission during low speed city driving. Hybrid cars can help the country reduce dependency on foreign crude oil and save money in the long term. United States imports almost half of the oil and gas from Middle East. Organization of the Petroleum Exporting Countries (OPEC) sets the price depending how much they have at its disposal. Many countries don’t have choice but to pay the price set by OPEC, regardless of supply and demand factors. If consumers purchase more hybrid cars, the dependency on foreign oil will decline and energy prices will drop. In 2012, US motor gasoline consumption was 8. 5 million barrels per day. If the consumption of gasoline continues at the rate it has during the last few decades, oil reserves will not meet demand in future. Countries will need to look for new wells across the world and this can lead to damages of our ecosystem. By using hybrid cars, oil consumption is reduced and there will be no need to start a search for new oil wells. The environmental benefits of hybrid cars also inclu de increased health for people . Use of oil products releases more pollution into the air that can cause cancers and lung diseases. Government Support The U. S. overnment has been providing hybrid vehicles buyers with income tax incentives to offset the higher cost of hybrid vehicles relative to their non-hybrid counterparts. 2 The hybrid vehicles is considered a promising technology by the National Energy Policy Development Group (2001), and their recommendation was to increase demand of hybrid vehicles in order to achieve economies of scale to bring the cost of hybrid vehicles down. 2 This group also recommended that government should provide a â€Å"clean fuel† tax deduction up to $2000 for the purchase of new hybrid cars during 2001-2005. The Energy Policy Act of 2005 replaced the income tax deduction with an income tax credit of up to $ 3,400 for vehicles purchased after December 31, 2005. The credits phased out after a manufacturer sold 60,000 of a hybrid model starting from January 1, 2006. As the Dec. 31, 2010, end for all credits neared, only a few hybrids still qualified for the credits. 2 In 2012 there are still some tax incentives for new plug-in hybrid cars purchases for up to $7500 in tax deduction for qualified buyers.

The average cost to replace this battery is between $ 6,000 and $10,000. People who travel a lot will not benefit from driving the hybrid car. †¢Recharge time: Fully recharging the battery pack can take four to eight hours. Bulk and weight: Battery packs are heavy and take up considerable vehicle space. †¢Slow acceleration: Hybrid cars have much slower acceleration times than a traditional cars that only use gasoline. †¢Low resale value: Hybrid cars have low resale value because of the costly batteries used in the hybrid cars that have to be replaced regularly. †¢Short supply: Because these cars are expensive their supply parts are available in different parts of the country. Present an d Future for Hybrid Cars The future looks bright for hybrid cars because price of oil will probably continue to rise and the mpact that fossil fuels have on the earth’s environment. Incentives, such as tax credits for purchasing a hybrid cars and grants for researching new battery technologies, will continue to improve their performance and make hybrid cars more attractive and competitive. The most recent hybrid technology is â€Å"plug-in hybrid car. This hybrid model offers the same benefit as hybrid cars, with added benefit of being able to be plugged in to home electric outlets for recharging when the car is not in use. 5 The competition in hybrid car industry is very challenging. The automobile industry is n oligopoly. There are only few big key players that are concerned about new entrants, the risk of substitutes emerging through new technology (Hybrid cars), changes in consumer taste and external regulations. Toyota successfully created a barrier for other car manufa cturer by introducing hybrid engine green technology. Toyota has dominated the market for years with its hybrid Prius and to remain competitive they will have to design new vehicles at low-cost using the most advanced technology. Every year, the Prius faces more competition as other car manufacturers are building heir own version of hybrid vehicles. Ford recently produced the C-Max hybrid car which outsold the Prius in January 2013. C-Max hybrid car is larger and family-friendly version of the Prius. 6 Ford executive are predicting that its 2013 hybrid sales total will be much higher that their current annual high to $35,496. 6 Nissan is also aggressively pushing hybrid sales in 2013. Hybrid cars are more expensive as compared to traditional gasoline vehicles and require frequent recharging for their operations but in future these issues will hopefully change. References 1.
