| Abstract: | The changes of temperature and stress distribution in a turbocharged diesel engine piston with toroide combustion chamber with and without squish lip respectively are analyzed by applying 3-di-mensions CAD/CAE technology. The solutions are of great value to the comprehensive optimum design for economy, exhaust emission and reliability of an engine. |
