The constant pressure turbo-charge system is widely used in marine diesel engines because of its high thermal efficiency. This study has been made to establish a simulation system for exhaust gas pulsation of the constant pressure turbo-charge system and to clarify its characteristics. The previous paper reported that the pressure fluctuations measured on test units and some engines agreed very well with those simulated by the scheme developed in this study. The study used the characteristic method for solving the differential equations of unsteady flow. This report will firstly discuss the high thermal efficiency of this turbo-charge system in the range of high mean effective pressure. Secondly it will show the advantages of the Two-step Lax-Wendroff's method in solving the unsteady flow equations in comparison with the characteristic method. Furthermore, it will present some characteristics of the pulsation and the unique pulsation resonance in this tubo-charge system.
