| Abstract:A 6-cylinder diesel engine was set as an example to describe the deformation of engine body during its manufacturing, assembly and application. The cause and influence factors are analyzed from the aspects of design, casting and machining. The improvement method and its results are introduced. It is suggested that the specific stress value of engine body should be given in design. |
