二元燃料エンジン。A gas passage R for supplying a mixed gas of air and gas fuel from a mixer 3 and an oil passage R for supplying oil fuel are connected to the cylinder head 2 so that the gas fuel to the mixer 3 is connected to the cylinder head 2 . An on-off valve 6 is provided in the supply path R0, a flow rate adjustment valve 7 is provided in the oil flow path r, and a fixing mechanism 8 is provided to fix the flow rate adjustment valve 7 in a state in which a set amount of oil is supplied for ignition. The on-off valve 6 is provided so as to be freely operable to release the fixing.
It is configured to be switched by inputting a command signal between a gas operation mode in which the opening and closing valve 6 is opened and the fixing mechanism 8 is maintained in a fixed state, and an oil operation mode in which the on-off valve 6 is closed and the fixation mechanism 8 is released. In the dual-fuel engine, when switching from the gas operation mode to the oil operation mode, a timer delays a fixing release command signal of the fixing mechanism 8 by a set time from when a signal for closing the opening/closing valve 6 is input. A dual fuel engine characterized by having 20 parts.
