METHOD FOR CONTROLLING FUEL INJECTION OF MARINE DIESEL ENGINE AND DEVICE THEREFOR

摘要

A method and a device for controlling fuel injection of a marine diesel engine wherein the control is exercised so as to match the loading condition at the time point of fuel injection are provided. The method comprises: a step of measuring the fuel injection amount and the rotational speed of the marine diesel engine a prescribed number of times at prescribed time intervals and inputting the measurements, a step of evaluating a relational expression satisfying the relation between the fuel injection amount and the rotational speed of the marine diesel engine, a step of calculating the fuel injection amount (u k ) that should be injected at present according to said relational expression when the rotational speed of the marine diesel engine is set to a target rotational speed, and a step of controlling the opening of the fuel injection valve of the marine diesel engine so as to match said calculated fuel injection amount at present.
