    The idea of the hybrid electric vehicle (HEV) has been around for longer than a decade, as many people may not have originally thought. In fact, hybrid vehicles have been in development for the past century. The combination of an electric motor and a gasoline engine has been stirring in the minds of scientists and inventors alike for many years. Hybrid cars have surpassed many feats as it's progressed through the years, such as increased gas mileage and reducing the pollutants that regular internal combustion engines expel. While the hybrid car is in high demand at the present time, some people believe these cars are just a quick resolution before bigger and better ideas, such as fuel cell vehicles, begin taking over the automobile industry. Still, the development of the hybrid car has had many effects on today's society and may continue to in the future.

    Hybrid cars use both gas and electric. The gasoline engine is the primary source of power, while the electric motor is used at low speeds. Emissions levels are reduced because the gasoline engine shuts off at low speeds. An additional benefit of the parallel configuration is that no outside source of electric power is required because the engine itself generates the required electricity. A Hybrid Electric Vehicle known as HEV have several advantages over traditional internal combustion engine (ICE) vehicles: Regenerative braking capability, which helps minimize the energy lost when driving. Engine is sized to average load, not peak load, which reduces the weight of the engine. Fuel efficiency is greatly increased, while emissions are greatly decreased. HEVs can be operated using alternative fuels; therefore they need not be depended on fossil fuels (http://www.ott.doe.gov/hev/what.html#hev). Another great thing about these machines is the mpg; on the average, a hybrid car gets anywhere from 55-70mpg on the hwy. This is what makes the car all worth having. Now all this sounds good, but there are some issues that must be addressed.

  • Hybrid Electric Vehicles and Their Advantages

    919 Words  | 2 Pages

    In this day and age car manufactures are trying to out-compete one another in terms of car features and sales. Technology has come a long way since 1905 but the principle is still the same: to produce hybrid vehicles that not only can compete with standard vehicles in terms of price and available features, but that also offer better mileage and less pollution. One may understand why hybrid vehicles are a good choice, but one may not understand why more auto manufacturers have turned to hybrids instead of electric vehicles. 'HEVs do not share an electric vehicle's main drawback: limited range between chargings. The few thousand electric vehicles on the roads in the U.S' can travel only about 80 miles before their batteries need recharging, which can take anywhere from three to eight hours'(1, pg1). For those who do not wish to be constrained by having to charge up batteries and worry about mileage, HEVs are the next logical choice.

  • Case Study: Electric Cars

    542 Words  | 2 Pages

    Electric cars are becoming increasingly more necessary, and have more advantages than disadvantages. Electric cars help to decrease the noise, pollution as they are much quieter. They do not emit any (or much less) carbon emission than petrol cars. Electric vehicles are the greenest mode of transport in the personal transportation industry. For each litre of fuel used in an engine produces more than 2.5kg of CO2. CO2 will be produced by an electric car but still a very little amount. It is also possible to use renewable power or a green energy supplier in the electric car. Thus it would lead to less polluted and safe working environment for all of us. However, safety is a big concern with using vehicles. The fluids in the batteries actually take impact better than a fully made gas car because it is not that flammable. Petrol cars and diesel cars are more flammable than electric cars so they are greater of taking impact in the event of an accident. I think that this is a very good reason because fewer people would get injured or hurt. This would save money because electricity is cheaper than gas and electric cars are easy to operate. Also is very ECO –friendly which mean that it is cheaper to run and have to pay very little road tax. In a pure electric vehicle there’s nothing combustible and have far fewer moving parts than you would find in a petrol or diesel car.

    Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity.

    Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.

    Electric cars help lower emissions because they have completely clean motors. As time progresses, emission standards rise and will become harder to meet for automakers. Electric motors will always have zero emissions and auto makers won't have to spend extra money to make their engines cleaner and more fuel efficient. Originally, when the internal combustion engine was invented, pollution wasn't a problem. After hundreds of years and the many combustion engines created, all the exhaust has built up. Today, pollution is one of the largest problems in our environment. Every year the average miles driven rises for everyone. When this rises, the pollution rises as well. Toni Marzotto, in "The Evolution of Public Policy: and the Environment," explains how air pollution will continue to keep on increasing:
