The intake stroke
In this process, an engine intake valve opening, exhaust valve closing. As the piston moves from top dead center bottom dead
Point moves, the cylinder volume above the piston is increased, so that the pressure inside the cylinder to atmospheric pressure or less,
That is caused by vacuum suction in the cylinder, so that the air will be drawn into the cylinder through the intake duct and the intake valve, with
When the discharge nozzle atomized fuel mixed with air. At the end of the intake gas pressure within the cylinder
About 0.075-0.09MPa. At a time when the temperature of the combustible mixture in the cylinder has been increased to 370-400KExhaust stroke
When the expansion stroke (power stroke) near the end, the exhaust valve opens, by the pressure of the exhaust gas discharge freely
Gas, the piston reaches bottom dead center and then moving at top dead center, the exhaust gas is forced into the atmosphere, this is the row
Suction stroke. In this stroke, the cylinder pressure slightly above atmospheric pressure, about 0.105-0.115MPa.
When the piston reaches the vicinity of top dead center, the exhaust end of the trip, when the exhaust gas temperature is about 900-1200K.
Thus, we have introduced over a working cycle of the engine room, the bottom dead center of the piston in this period
Reciprocating four stroke, with a corresponding crankshaft rotation for two weeks.
