Diesel engine is a heat engine that uses diesel as fuel to convert chemical energy into mechanical energy. The ignition mode of diesel engine is different from that of gasoline engine. The mixture in the cylinder of diesel engine is compression ignition rather than ignition. The diesel engine has good economic performance and can produce greater torque under the same displacement. What is the working principle of diesel engine? Now let the diesel engine manufacturer give you a detailed introduction.

The diesel engine uses compressed air to generate high heat, which expands explosively after injecting atomized diesel. The pressure directly acts on the piston, pushing the piston to reciprocate along the cylinder in a straight line with unequal speed. Through the crank connecting rod mechanism composed of piston pin, connecting rod and crankshaft, the linear motion of the piston is transformed into the rotary motion of the crank, thus outputting mechanical work.

The working process of diesel engine has many similarities with that of gasoline engine. Each working cycle also experiences four strokes: intake, compression, power and exhaust. However, because the fuel used by diesel engine is diesel, its viscosity is higher than that of gasoline, it is not easy to evaporate, and the autoignition temperature is lower than that of gasoline, so the formation and ignition mode of combustible mixture is different from that of gasoline engine. The main difference is that the mixture in the cylinder of the diesel engine is compression ignition, not ignition.

Compared with gasoline engines, diesel engines have the characteristics of good fuel economy, low nitrogen oxide content in exhaust gas, low speed and large torque., It is highly praised by European cars for its excellent environmental characteristics. However, in Europe's advanced automobile industry, riding comfort and noise are no longer a problem. At present, the performance and working conditions of diesel engines are almost the same as those of gasoline engines.
