| Abstract:Exhaust gas recirculation (EGR) is the most conceivable method to fulfill the coming IMO Tier III emission regulation. The investigation was operated on a single cylinder medium-speed marine diesel engine. The effect of donor cylinder on work process, performance and emission were studied by test and simulation, The investigation provides technical support for key measures selection for overcoming intake-exhaust pressure difference. |
