Fast Cars and a Clean Environment
Many people would love the idea of having the fastest car ever or just having a speedy and sleek sports car to drive around for that matter. The idea of being able to “flex” the power of your car every time the light turns green make people long for a high-speed car. Many automakers are making faster and faster or cars with more horsepower for this demand. For instance, BMW’s E36 (1996- 1999) M3 models peaked at an amazing 234 horsepower and 226 pounds per feet of torque, but this wasn’t enough for many BMW enthusiasts. So in 2001 BMW came out with its E46 M3 model that housed an astonishing 333 horsepower and 270 pounds per feet of torque engine, which is an increase of almost 100 horsepower from the previous E36 M3 models. This dealt with the demands for faster cars (1). There is a great price for living out this dream. The earth’s already depleting supply of fossil fuel and damage to the environment, such as the ozone layer, is being further injured from the combustion engines of cars. With the combination of more and more people learning about the environmental problems caused by combustion engines and the raised prices for gas caused by the huge demand for oil, automakers are now working on environmentally safe cars that consume less gas. Then why isn’t everyone driving an environmentally safe car right now if they know that they are killing the environment as they drive? One of the main reasons that many people have no intentions of ever purchasing these cars is simply because of the fact that these cars are known to have almost twice as less horsepower as an average car and therefore accelerate almost twice as slow. Many car enthusiasts, who love to drive fast cars, will have no reason to purchase a car that takes over ten seconds to go from 0-60 miles per hour. So the issue here is this: people want to have fast cars but they also want to have clean air. Yet all the fast cars our there pollute and destroy the environment.
Types of Engines: Internal Combustion Engines (4-stroke piston combustion)
Most, if not all cars on the road today, are powered by some variation of a four stroke internal combustion engine. Invented by Nikolaus Otto in 1867, a four stroke internal combustion engine powers a car by first taking in oxygen from the external air and mixing it with a small drop of gasoline into a small chamber(2). A piston also located inside that chamber takes the gas and air mixture and compresses it to form a more powerful reaction and is ignited by a spark plug. The energy from the explosion of the gasoline and air pushes the piston downwards and turns the cam which ultimately rotates the wheels. After the explosion, the combusted air is released into the exhaust pipe which then goes to the outside air. The engine is then ready to restart the whole cycle again: taking in new air, compressing it, combusting it and releasing the combusted air into the exhaust pipe. This process is basically...
