Internal combustion engine Essay Example for Free

Internal combustion engine Essay Electric cars should be used instead of cars that run with gasoline because electric cars do not harm the environment, are quieter, quicker, does not require gasoline and include a significant reduction to air pollution. Firstly, electric cars have a lot of benefits. One of them is that they are quiet, quick and smooth, making most regular cars look clunky and outdated. What surprises people the most is the torque (axle-twisting power) offered by the electric cars. Step on the accelerator and power is delivered immediately to the wheels, providing a thrilling driving experience. Secondly, after a while with an electric car you will forget that gas stations existed. Imagine never going to a gas station and spending all that money for fuel. All you have to do is pull your vehicle in your drive way or garage and plug it in to the charging inlet. It is very convenient to just wake up the next morning and have a fully charged vehicle that can go up to 100 miles. In addition they are cheaper to operate. Almost everywhere in the world, electricity is very cheap. So when you compare an electric vehicle to a regular car, the cost per mile to fuel an electric vehicle is approximately one-third to one-quarter the cost of gasoline (on a cost per mile basis). Nevertheless, owning a car is associated with the responsibility of maintaining it. Regular cars require frequent maintenance but this is not the case in electric cars. These cars do not suffer same level of stress as traditional engines acquire and do not require frequent oil changes and other regular maintenance. On the other hand, electric cars have a lot of disadvantages too. First of all the limited range of the electric cars is probably the biggest disadvantage. Most affordable electric cars only have about 80 to 100 miles of range. Which is not enough if you are for instance going on a long road trip. People who have electric cars need to properly plan, assuring that they will not go over the limited range. Not to mention, they also have a long refueling time. It is not like going to a gas station and adding a couple of hundred miles of range in five or ten minutes. To recharge a completely empty electric car would take about 10 hours depending on the voltage. With 120 volts (which is the current voltage in every house) it will take ten hours. With 240 volts it takes about four to five hours to fully charge the electric vehicle. Also, you would have to have the right place to charge your electric vehicle. You cannot go more than the car’s limit but you the right place to charge it. For instance people who are living in apartments cannot own electric cars because they do not have a garage to charge their vehicle. Big electric car companies have charging stations where you can get your vehicle fully charged in 1-2 hours but there are not a lot like gas stations. Furthermore the higher cost is probably what keeps people away from electric vehicles. The current electric cars are priced between 30. 000 and 40. 000 dollars. While you can buy, for instance the Honda Fit, Ford Focus etc. for less than 20,000 dollars. Last but not least, electric cars are costly to maintain and repair if there is a big problem with the car. Since electric cars are in a class of their own, owners may wind up paying more on repairs and maintenance because not every mechanic is trained to repair and maintain electric cars. In conclusion, when considering the pros and cons of electric cars, it is clear that there are some major advantages and disadvantages of owning an electric car. At the end, if these cars help people save a tremendous amount of money and help the environment, the pros of owning an electric car will outweigh all of the cons.
