The Application of Casting Technology on Engine Key Components——The Engine Localization of Mercedes-Benz and Volvo as Examples

With 4C ( crankshaft,camshaft,cylinder block and cylinder head) of Mercedes-Benz M274 /M270 and Volvo VEP4 ( both new developed 4-cylinder petrol engines) as study objects,the application of casting technology on these 4 parts was analyzed. The performance of nodular cast iron shell mold crankshaft reaches the performance of forged type crankshaft in small displacement engine,it is encouraged to replace forging type crankshaft by casting crankshaft. Low alloy cold hardened iron shell mold hollow camshaft have the production conditions for mass production and will still account for a larger share of market. Al alloy high pressure die casting cylinder block and gravity casting cylinder head are the main development trend and sufficient for mass production.
