Marine natural gas engine simulation method and device and electronic equipment

The invention relates to a marine natural gas engine simulation method and device and electronic equipment, and belongs to the technical field of marine engines, and the method comprises the steps that a low-temperature premixing marine natural gas engine combustion model is built, and the combustion model divides a combustion area in a cylinder of the engine into an ignition fuel combustion area and a natural gas diffusion combustion area; combustion parameters of the combustion model are obtained, and the mass of first mixed gas entrainment in the ignition fuel combustion area and the mass of second mixed gas entrainment in the natural gas diffusion combustion area are calculated based on the combustion parameters; combustion parameters are adjusted, so that the first mixed gas mass is not smaller than the second mixed gas mass, and engine misfire simulation is completed. According to the invention, simulation is carried out on engine misfire by constructing the ship combustion model, and the requirement of
