設しである事を特徴とする二元燃料エンジン。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 as to communicate with the cylinder head 2. An on-off valve 6 is provided in the gas fuel supply path R1, and a flow rate adjustment valve 7 is provided in the oil flow path r.
a gas operation mode in which a fixing mechanism 8 that is fixed in a state where a set amount of oil is supplied for ignition is freely operated to release the fixing, and the opening/closing valve 6 is opened and the fixing mechanism 8 is maintained in the fixed state; The dual-fuel engine is configured to be switched by command signal input to an oil operation mode in which the on-off valve 6 is closed and the fixing mechanism 8 is released, and the gas operation mode is switched to the oil operation mode. In addition, a timer 14 is provided to delay the identification release command signal to the fixing mechanism 8 by a set time from when the signal for closing the on-off valve 6 is inputted, and the tie? -14 is characterized by being provided with a mechanism 18 that changes and sets the delay setting time so that the higher the engine load, the shorter the delay setting time based on the engine load at the time when the closing signal is input to the on-off valve 6. Dual fuel engine.
