Abstract
PURPOSE: To accurately control the time of fuel injection at starting in the cold state, by providing a heater for a working oil feeder for supplying working oil to the hydraulic actuator of a device for adjusting the time of fuel injection.
CONSTITUTION: A hydraulic actuator 103, which makes a rotational phase difference between an input shaft 2 which is driven by an internal combustion engine and an output shaft for driving a fuel injection pump P, is provided. Working oil is supplied from a pump 9 to the hydraulic actuator 103. A heater 12 is provided downstream to a relief valve 11. The heater 12 is put in operation by a heater controller 13 when the internal combustion engine is started in the cold state. Since the heater 12 is put in operation synchronously with preheating at the time of starting of the engine in the cold state, the hydraulic actuator 103 is smoothly operated even at the time of starting of the engine in the cold state to accurately control the time of fuel injection.
