DEVICE AND METHOD FOR STARTING INTERNAL COMBUSTION ENGINE

摘要

A device and method for starting an internal combustion engine, provided with an exhaust turbine supercharger (12), an electric motor (32), a power storage unit (35), an engine rotation starter device (24), injectors (18), and a control device (38) that controls the electric motor (32), the engine rotation starter device (24), and the injectors (18), wherein, when an engine rotation activation start signal (102) is input and the rotational frequency of the exhaust turbine supercharger (12) reaches an engine rotation-activation-starting rotational frequency, the control device (38) begins driving the engine rotation starter device (24), and when the engine rotational frequency reaches a fuel-supply-starting rotational frequency, the control device begins driving the injectors (18), thus improving the starting performance of the internal combustion engine.
