PART 11.1 Two types of vehicle regarding fuel efficiency and emissionThere are two kinds of vehicle, one which is driven by battery packed power and theother ones are the conventional one which are driven by gasoline products like petrol and diesel.Both are having significant role in the process of internal combustion engines (Jin and et.al.,2016). The battery packed vehicle which are also known as electric vehicles, are used to reducethe carbon emission and to protect the environment.As far as the look is concerned, electric vehicle looks exactly the same like the petrolvehicle but there will be no tail pipe or exhaust pipe in electric car as they are not giving exhaustbut the petrol car will be having exhaust pipe as these vehicles are burning fuel and producingexhaust. Apart from these, conventional cars are having a tank specially for the storage of petrol,but in electric car there will be a battery storage system that will supply the required electricity tomove the engine. The conventional vehicles are having engine which consist of piston cylinderarrangement, and by generating the power from this arrangement, the vehicle is moved, but inelectric vehicle the power to move the vehicle is generated by the electric motor.Electric vehicle are having two batteries which are either lead-acid battery or lithium-ionbattery of 24 v each, and these batteries are connected in parallel, so that they can get themaximum power output (Poullikkas, 2015). These batteries are charged by electricity and can beused after that. Nowadays the batteries are made in such a way that they can get charged fasterand can run for longer duration of time. The main advantage of having electric vehicle is thatthey are carbon emission free, as in those vehicles no combustion process of fuel is taking place,so no carbon emission, but the disadvantage is that they can not take the heavy load, because ofthe size of the battery. The size of battery is smaller so that it can be fitted in place, that's whythese vehicles are not made to carry heavy load but they can use in protecting the environment.Conventional vehicles are the one which are driven by either petrol or diesel. Theseengines are the internal combustion engines as the combustion process is carrying out inside acylinder. These vehicles are made in such a way that they can carry heavy load and with greaterspeed. The combustion process is very fast, because only a small spark is needed to ignite thefuel and to run the vehicle (Dunn and et.al., 2015). These vehicles are emitting carbon, as thefuel which is burnt might be having some un-burnt particles left inside and which contains
carbon, and after the combustion process, these particles are thrown out to the environment andthat is very dangerous. Nowadays the fuel companies are purifying the fuel which is having verylow Sulphur percentage so that it will release fewer gases which may contain un-burnt particles,and the emission of the carbon will be low, but at the same time some percentage of carbon canstill cause the damage to the environment (Onat, Kucukvar and Tatari, 2015). Traditionalvehicles are having a primary advantage is that they can carry more load as compare to theelectric vehicle, and to the long distance with the speed which is higher than the electric vehicle.Traditional vehicle can either be a petrol vehicle or a diesel vehicle. Diesel vehicle are morestrong and robust than petrol vehicle and these vehicles can carry more load than petrol vehicle.But the carbon emission in diesel vehicle is more due to the knocking effect. When thecombustion in the engine does not start correctly than it produces sound and that is known asknocking. Due to knocking effect the carbon emission is more in diesel engines. Electric vehiclesare very good and they do not harm the environment but to carry more load and to travel more,people always prefer the traditional vehicles (Xie, Lin and Nealer, 2017).Though, people now prefer conventional vehicle more, but they realized that electricvehicle are more easy to use and to run. Conventional vehicle need a lot of maintenance, and itwill start from the first month after buying the vehicle. The maintenance like changing the oilfrequently, and the exhaust system repairs, all these things should be taken care of and that toowith precision and accuracy. Electric vehicles are having less moving parts as compare to theconventional vehicle, so they will require less maintenance. Electric vehicle are very cheaper tomaintain and these vehicles are more energy efficient also, so the owner of that vehicle can savea lot of money over the period.There are some advantages and disadvantages of having an electric car and conventionalcar, some of them are as follows;The range of the electric car is lower and it can only goes up to 100-200 miles and if thecar is conventional then it can go up to 500-600 miles without refuelling.In conventional cars, the refuelling can be easily done by going to the pump, but not thecase with electric car, because you have to wait for the car to be charged but this can takelong time (Kihm and Trommer, 2014.).No carbon emission or any type of noxious substances are released in electric car, but inconventional car, the emission occurs due to the combustion process.
