A pilot injection device for a fuel injection pump has an accumulate piston movable in response to a fuel pressure from a pressurizing chamber of the fuel injection pump to cause a pilot injection prior to a main injection by the pump. The device is provided with a back-pressure chamber filled with fuel and having a volume variable by the movement of the accumulate piston. Air trapped in the back-pressure chamber can be removed therefrom through a hole to improve the operation characteristic of the pilot injection device.

The present invention discloses an improved control apparatus for a Diesel engine. The control apparatus includes an auxiliary intake air throttle device as well as a conventional main throttle device, which is actuable and throttles intake air only during engine idling and light-load operation in order to reduce the engine noise. The apparatus is further provided with a fuel metering device for ensuring the precise control on fuel metering when the auxiliary intake air throttle device is actuated so that the engine stall may be prevented.
