CHARACTERISTICS OF EXHAUST GAS PULSATION OF CONSTANT PRESSURE TURBO-CHARGED DIESEL ENGINES

The constant pressure turbo-charge system has now been increasingly adopted for marine diesel engines because of its higher thermal efficiency in the range of higher mean effective pressure. In this study, a gas flow model of the constant pressure turbo-charged diesel engines was assumed as a basic and fundamental one, and an investigation was made of it. As a result,some characteristics of the exhaust gas pulsation of this system have been clarified and a mathematical simulation system has been established. It is emphasized that the filling and emptying method which neglects wave propagation cannot simulate the pulsation, although it can simulate the average exhaust gas pressure and temperature of this system.
