Advantages Of Diesel Engine Aug 24, 2017

The advantages of the diesel engine are that the torque is great, the economic performance is good, and every working cycle of the diesel engine goes through the gas, compression, work, exhaust four strokes, but because diesel engine fuel is diesel, its viscosity than gasoline, not easy to evaporate, and its spontaneous combustion temperature is lower than gasoline, so the formation of combustible mixture and ignition methods are different from gasoline engine.

The main difference is that the mixture of diesel engine cylinders is pressurized, not ignited. Diesel engine work when the air into the cylinder, the air cylinder compressed to the end, the temperature can reach 500-700 ℃, pressure up to 40-50 atmospheres.

When the piston is close to the stop point, the high-pressure pump on the engine sprays diesel oil into the cylinder with high pressure, and the diesel forms fine oil particles, with high pressure and high temperature air mixing, diesel mixture combustion, violent expansion, the production of explosive force, pushing the piston down work, at this time the temperature of up to 1900-2000 ℃, pressure up to 60-100 atmospheres, the resulting torque is very large, so diesel engine widely used in large diesel vehicles.
