The specification of automotive engine cylinder block cast:
The cylinder block is the main engine that will each cylinder and crankcase fused, is to install the support skeleton pistons, crankshafts and other parts and accessories. On modern vehicles have adopted the basic water-cooled multi-cylinder engine, for a multi-cylinder engine, the cylinders are arranged in the form of the engine determines the dimensions and structural characteristics of the engine block rigidity and impact strength, and the relationship to the general arrangement of a car, auto engine cylinder block should have sufficient strength and rigidity.
We has produced automotive injection cylinder block or die casting engine cylinder cover for FAW-VOLKSWAGEN.
