Gasoline label knowledge popularization: compression ratio/evaporation efficiency/combustion salesv

The internal combustion engine equipped with a gasoline engine has four strokes, namely: intake injection, compression and evaporation, expansion and work, and exhaust gas. The function of the compression stroke is to increase the internal temperature of the combustion chamber before combustion, and evaporate the liquid gasoline injected into the cylinder at high temperature. You must know that gasoline will burn slower in the liquid state, while in the gaseous state it will reach the efficiency of "deflagration". Therefore, compression evaporation is the most important step, and the air entering the cylinder is compressed to generate high temperatures, because the compression process accelerates the intensity of molecular movement
