| Abstract: | Diesel engines have attracted increasing attentions due to their high power,high durability and low maintenance cost.Therefore,they have been successfully installed on light-duty passenger cars as well as heavy-duty trucks and engineering plants.Compared with gasoline engines,the diesel engines possess better fuel efficiency with lower emission of carbon oxides and hydrocarbon due to the high compression ratio and relatively high O2 concentrations in the diesel combustion chamber.However,a large amount of s... |
