The main rotating engine parts, installed after the upper link can carry up and down the connecting rod (reciprocating) movement into a cycle (rotation) movement.
Is an important engine parts, the material is made from carbon steel or ductile iron made, there are two important areas: The main journal, connecting rod neck, (and others). Spindle neck to be installed in the cylinder, the connecting rod journal and connecting rod hole to connect, connecting rod small end hole and the cylinder piston connection, is a classic crank...Crankshaft and the rocker arm lubrication mainly refers to the lubrication between the bearing and two fixed points of lubrication.
This is generally pressure lubrication, there will be a crank bearing oil path and all connected, after running through the engine oil pump to provide pressure oil for lubrication and cooling.
Engine working process is that the piston through the mixing of blasting compressed gas, to promote the piston to do linear motion and force to pass through the connecting rod to crankshaft, crankshaft to the rotary motion into linear motion...Engine crankshaft rotation is the power source...Is also the source for the entire mechanical system.
