| Abstract:The installation of crankcases for large power diesel engines has always been inconvenien, as the engine block wall is too thin which may lead to drilling through of bolt hole for the installation of seal cover cap.To solve this problem,a new type of crankcase cover for large power diesel engines was optimally designed. The type selection and design of key components are introduced in detail. It is verified by tests that the crankcase cover could meet the diesel engine performance requirements, realize easy installation and save labor cost. |
