- the diesel engine starts when the cell motor 63 after the check time ⁇ has elapsed is zero.
- the warning method is generally a warning light or the like, but is not particularly limited in this embodiment.
- the CSD30 is an actuator that operates only at a low temperature start, and it is difficult to detect a failure except at a low temperature. Therefore, as in this embodiment, the reliability of the fuel injection pump 1 can be improved by detecting the failure of the CSD 30 every time the diesel engine is started, regardless of the engine water temperature (cold temperature).
- the CSD30 is a device that changes the fuel injection amount according to O ⁇ ⁇ OFF.
- the CSD30 is turned off at the same time as starting the engine to detect a failure, an excessive amount of fuel injection will be supplied to the diesel engine, resulting in black smoke deterioration. Therefore

It is also possible to check the operation of the advance angle actuator 38 by checking. In this way, the safety of the fuel injection pump 1 is improved by detecting the failure not only by the controller 60 but also by the hearing of the operator.
- the present invention is applicable to an engine having a cold start advance angle mechanism.
