| Abstract: | In order to solve the failure of cylinder head on a 4-cylinder turbocharged and intercooled diesel engine in trial,failure analysis is taken on changes of design, work conditions, appearance, chemical composition, metallography, stress.On the basis of principle of improvement, through FEM calculation and comparison of different measures, final methodsare decided. Stress test proved that new design can settle down the failure problem, as well as enhancing reliability ofengine. |
