| Abstract:AVL-Boost simulation software is employed to simulate the premixed combustion performance of a certain marine high-speed diesel engine. The analysis shows that the diesel engine with the two-stage turbocharging system could effectively improve the power, low-speed torque performance, acceleration performance, and decrease the fuel consumption, and improve the emissions. It is also pointed out that the two-stage turbocharging system is complex, has relatively big size and quality, thus is hard for installation and connection. The solutions to deal with these problems are also discussed. |
