Simulation of working process of marine diesel engine in a comprehensive method

The working process of marine diesel engine is simulated by combining mean value engine model and volumetric model. It reflects some average parameters such as effective pressure, effective power and engine speed, as well as reflects real-time explosion pressure, maximum temperature in cylinder and indicator diagram. In order to accelerate the simulation, Crank Angle and cylinder pressure is imported into MATLAB workspace, and a diesel model based on BP neural networks is built. The cylinder pressure can be shown in marine simulator by using trained BP neural network.
