Hybrid Engine Vehicle
According to the expert, the change of climate change becomes increasingly serious. In regard to this problem, more and more people realize that the change of climate, which can be seen from global warming, is mainly due to those greenhouse gases. In order to mitigate the problem of climate change, generally there is a need to control and cut down the emission of Carbon dioxide.
In regard to the emission of CO2, the widely used vehicles over the world contributes quite a lot. A report shows that more than 10 percent of CO2 emission comes from fossil fuel processing and distribution(IPCC 2007). Therefore it is a possible way to mitigate Carbon dioxide emission by changes on vehicle engine to decrease the consumption of fossil fuel. Consequently, hybrid engine comes to be a good choice.
A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles, which combine an internal combustion engine and one or more electric motors. It includes a propulsion system additional to the electric motors, to be not hampered by range from a charging unit like a battery electric vehicle. Hence, hybrid engine vehicle does have yields of advantages on mitigating the climate change.
Firstly, using hybrid engine vehicles could cut down the consumption of fossil fuel, which is one of the good ways to cut down the emission of CO2. Although some still say that hybrid engine also cost carbon dependent fuel, mitigate the emission is the first step to decrease the total amount of Carbon dioxide. Furthermore, aim at the increase of cost for the new vehicle which is considered by lots of people, hybrid engine shows its economic benefit on a large scale improvement of whole environment. Moreover, hybrid engine increases the utilization ratio of the energy. It takes advantage of the mechanical energy or heat from the engine itself so that less fuel is costed.
Therefore, in order to control and then mitigate the gradual change of climate, hybrid engine is the good choice.
