Method, device and equipment for correcting fuel injection quantity of engine and medium

The invention discloses a fuel injection quantity correction method, device and equipment of an engine and a medium, and belongs to the technical field of automobiles. The fuel injection quantity correction method of the engine comprises the steps that the air temperature and the water temperature of the engine are obtained; based on the air temperature and the engine water temperature, a corresponding fuel injection amount correction coefficient is determined; the fuel injection amount is corrected based on the fuel injection amount correction coefficient, and the corrected fuel injection amount is obtained; and an engine fuel injector is controlled to inject according to the corrected fuel injection amount, the technical problem that in the prior art, due to the fact that the temperature of fuel in an engine is different, the fuel density is different, and the mass of the fuel actually participating in combustion and the mass of the fuel theoretically participating in combustion are further greatly deviated
