A device and a method for starting an internal combustion engine, provided with an exhaust turbine turbocharger, an electric motor generator, a power storage unit, an engine rotation starter device, injectors, and a control device that controls the electric motor generator, the engine rotation starter device, and the injectors, wherein when an engine rotation activation start signal is input and the rotational frequency of the exhaust turbine turbocharger reaches an engine rotation-activation-starting rotational frequency, the control device starts driving the engine rotation starter device, and when the engine rotational frequency reaches a fuel-supply-starting rotational frequency, the control device starts driving the injectors, thus improving the starting performance of the internal combustion engine.

Device and method for starting internal combustion engine

According to a device and a method for controlling an internal combustion engine, a control device () enables controllability of the internal combustion engine to be improved by preventing surging from occurring upon starting or stopping of the internal combustion engine, by opening a relief valve () as a turbine rotational speed reaches a surging rotational speed when the control device () causes a motor generator () to assist in rotation of the turbocharger () upon starting of a diesel engine body ().

Internal combustion engine, and device and method for controlling internal combustion engine

A ship powered by an internal combustion engine () and an electric motor () connected to a propeller () powered by surplus electric power obtained by a thermal discharge recovery system has a controller including a feedback control section for controlling a base amount of fuel injected to the internal combustion engine () based on the difference between the target number of rotation of the propeller given by the operator and the real number of rotation, and a feed-forward control section having a means () for calculating an overall power output and a means () for calculating a correction in the amount of fuel injected to the internal combustion engine based on the overall power output and the number of rotation of the propeller. The base amount of fuel is corrected by subtracting the correction obtained by the feed-forward section from the base amount of fuel calculated by the feedback control section whereby preventing a rapid change in the speed of the ship due to rapid change in ship loads.
