Four-stroke diesel engine works the intake stroke of the first stroke - Shandong diesel engine air intake, its task is to make the cylinder filled with fresh air. When the intake stroke starts, the piston is at top dead center point of the diesel engine, the combustion chamber within the cylinder also left some exhaust gas. When the crankshaft rotates the elbow, so that the piston rod dead point moves down from the top dead center, at the same time, the use of the transmission mechanism associated with the crankshaft so that the intake valve opens. With the downward movement of the piston, the volume is gradually increased above the piston in the cylinder: causing the air pressure within the cylinder is lower than the pressure within the intake pipe of the diesel engine manufacturers, so the outside air is continuously charged into the cylinder.
