| Abstract: | This paper investigated the structures and mechanical properties of different parts of 4DA1 cylinder block.Discussion and analysis are also carried out about the differences of structures and properties between every part of the casting and the causes are also traced.The results show that the major cause for the differences lies in the different conditions of solidifying and thus a better way is found for further improving the qualities of the casting of 4AD1 engine. |
