For the overheating problems such as cylinder gasket sinter ,oil carbonization and liner slight scuffing during the development of a turbocharged engine ,five optimized shcemes of engine water jacket were proposed and evaluated according to manufacturing process ,manufacturing economy ,engine reliability ,and CAE results and finally two schemes were selected . According to the selected shemes , the water jacket test specimen was produced and tested . The final engineering applied scheme was determined by analyzing the test results of test specimen .According to the bench endurance test and the disassemb‐ling of engine ,the solution of overheating problem was confirmed .
