元燃料デイーゼルエンジン。 A dual-fuel diesel engine employing a side-injection combustion method that injects fuel from around the cylinder cover, and is equipped with multiple sets of oil-fuel injection valves and gas-fuel injection valves that eject oil fuel with good compression ignition properties. The upper and lower ends of the plunger lead of the actuator pump that drives the gas injection valve are shaped so that the injection start timing and injection end timing change, respectively, and the leads are shaped so that the effective compression stroke of the plunger is smaller. Formed so that the start of injection is early and the start of injection is delayed as the effective compression stroke increases,
An oil/gas dual fuel diesel engine characterized in that the upper end of the plunger lead of the oil/fuel injection pump has a constant shape at the beginning of injection.
