Patent ID: 7121245

Claim:
An injection control device for a fuel injection pump comprising: (a) a water temperature sensor; (b) a cold start device for advancing a fuel injection timing to an engine when started up in a low temperature; and (c) a controller, wherein the controller recognizes a value of water temperature by a signal from the water temperature sensor, and activates the cold start device when the engine is started up and when the value of water temperature recognized by the controller is lower than a threshold value of water temperature, and wherein, if a value of voltage of a power source of the controller becomes lower than a threshold value of the voltage of the power source during activation of the cold start device, a value of water temperature recognized by the controller immediately before the value of voltage of the power source becomes lower than the threshold value of voltage of the power source is maintained as the value of water temperature recognized by the controller for activating the cold start device.
