Diesel engine has no throttle, diesel speed control is to adjust the size of fuel supply to achieve the speed control, gasoline engine throttle is actually to control the mixture, so as to achieve the control of the engine.
1. The advantages of a diesel engine are high torque and good economy. The working process of diesel engine is similar to that of gasoline engine in many aspects. Each working cycle also experiences four strokes of intake, compression, work and exhaust.
2. But because the fuel used in diesel engine is diesel, its viscosity is higher than gasoline, it is not easy to evaporate, and its spontaneous combustion temperature is lower than gasoline. The main difference is that the mixture in the cylinder of a diesel engine is compression-ignition rather than ignition.
