What are the advantages of diesel engines?


 

1, the working principle of diesel engine: diesel engine is compressed air produces high heat, spray into the atomized diesel explosion expansion, the pressure directly acts on the piston, pushing the piston along the cylinder for unequal speed linear reciprocating motion, through the piston pin, connecting rod and crankshaft composed of crank connecting rod mechanism, the linear motion of the piston into the rotary motion of the crank, so as to output machinery work


 

2. The advantages of diesel engine are large power and good economic performance. The working process of diesel engine and gasoline engine has many of the same places, each working cycle also goes through intake, compression, work, exhaust four strokes. However, as the fuel used by diesel engine is diesel, its viscosity is larger than gasoline, it is not easy to evaporate, and its spontaneous combustion temperature is lower than gasoline, so the formation and ignition mode of combustible mixture are different from gasoline engine. The main difference is that the mixture in the cylinder of a diesel engine is compressed-fired, rather than ignited.
