However, because the fuel used by diesel engine is diesel, its viscosity is higher than that of gasoline and it is not easy to evaporate, but its auto-ignition temperature is lower than that of gasoline. Therefore, the formation and ignition mode of combustible mixture is different from gasoline. The main difference is that the mixture in the cylinder of diesel engine is compression ignition, not ignition.
The traditional diesel engine has high thermal efficiency and good economy. Diesel engines use compressed air to raise the air temperature, so that the air temperature exceeds the auto-ignition point of diesel. At this time, diesel, diesel spray and air are simultaneously injected and ignited.
