Intake Stroke Of Gasoline Generator

During this process, the intake valve of the engine opens and the exhaust valve closes. As the piston moves from the top dead center to the bottom dead center, the volume of the cylinder above the piston increases, so that the pressure in the cylinder will be below atmospheric pressure, that is, vacuum suction is created in the cylinder, so that the air flows through the intake pipe and enters. The valve is sucked into the cylinder, and at the same time, the atomized gasoline and air are fully mixed from the fuel injector. At the end of the intake, the gas pressure in the cylinder is about 0.075-0.09MPa. At this time, the temperature of the combustible mixture in the cylinder has risen to 370-400K.
