In gas engines that control the opening of gas fuel injection valves by hydraulic pressure, the gas fuel injection starts at the upper end of the plunger lead of the hydraulic control pump as an actuator used in the gas fuel supply device.The gas fuel injection amount increases. In addition to setting up a reverse lead so that it advances as the
This fuel supply device for a gas-fired diesel engine is provided with a pause groove for interrupting the injection of gas fuel, a plunger land for injecting the gas fuel again after a certain period of time, and configured so that the late injection timing coincides with the ignition timing.
