The difference between diesel and gasoline engines

Nov 12, 2021

Diesel and gasoline engines are the two most common types of power units in cars. Because of different fuels, diesel and gasoline engines work differently. Automobile teaching instruments are mainly manifested in the following aspects. First, the injection method is different. Generally, gasoline engines (except direct injection engines) mix gasoline with fuel and enter the cylinder, while diesel engines directly inject diesel into cylinders filled with compressed air. 

Secondly, the ignition method is different. Gasoline engines require spark plugs to ignite the mixture, while diesel engines ignite by compression ignition. Automobile training equipment manufacturers Finally, the compression ratio is different. The compression ratio of a diesel engine is generally larger than that of a gasoline engine. Therefore, its expansion ratio and thermal efficiency are higher, and its fuel consumption is lower than that of a gasoline engine.
