Gasoline Engine

Gasoline Engine is composed of two major mechanisms and five major systems, namely the crank connecting rod mechanism, the valve mechanism, the fuel supply system, the lubrication system, the cooling system, the ignition system and the starting system. The working principle of the gasoline engine can be simply understood as a four-part system. Gas-compression-work-exhaust. The biggest difference from diesel engines is that the ignition method of gasoline engines is ignited, that is, the mixture of air and gasoline injected by the gasoline injector enters the cylinder. After the cylinder exhaust valve is closed, the piston compresses the mixture from bottom to top. After the gas is compressed, the cylinder The pressure and temperature of the mixed gas inside increase accordingly. Then the spark plug ignites and the mixture burns violently. The temperature and pressure in the cylinder rise sharply. The high-temperature and high-pressure gas pushes the piston down, drives the crankshaft to rotate through the connecting rod, and then completes the exhaust process. The entire gasoline engine completes a process of doing work. . By analogy, the connecting rod drives our wheels to start running
