ある二元燃料エンジン。A gas passage GR that supplies a mixed gas of air and gas fuel from a mixer 4 and an oil passage OR that supplies oil fuel are connected to the cylinder head 2, and
A flow rate regulating valve 3 is provided in the gas flow path GR, an engine exhaust gas driven supercharger 5 is connected to the air supply path r□ to the mixer 4, and a gas fuel supply path to the mixer 4 is connected. r2, a flow path opening/closing valve 6 and a pressure regulating valve 7 located on the downstream side of the flow channel are respectively provided, and a diaphragm 16 for operating the pressure regulating valve 7 is connected to a spring 18 and the air supply channel. It is provided so that it is operated to the pressure increasing side by the pilot air from r1 and to the pressure reducing side by the gas pressure after pressure adjustment, and there is a gas operation mode in which the opening/closing valve 6 is opened and the operation is performed mainly using gas fuel, and the opening/closing mode is operated mainly on gas fuel. Valve 6. The dual-fuel engine is configured to be switched by a command signal to an oil operation mode in which the diaphragm is closed and operated on oil fuel, and the pilot flow path r4 for pilot air flow is adjusted to adjust the air pressure supplied to the diaphragm.
The dual fuel engine is equipped with a pressure regulating valve mechanism 20 connected to the engine so that the pressure regulating valve mechanism 20 is automatically adjusted according to the engine load so as to reduce the pilot air pressure when the engine load is low.
