WIPO Patent Application WO/2015/129547
Kind Code:
A1
Abstract:
A dual-fuel engine capable of minimizing the supply of excessive amounts of heat when fuel is switched, and a method for controlling a dual-fuel engine. A dual-fuel engine (1) provided with a diesel mode in which the dual-fuel engine (1) is driven by petroleum alone and a gas mode in which the dual-fuel engine (1) is driven by petroleum and gas, and also provided with a control unit for switching between diesel mode and gas mode and controlling the amounts of both petroleum and gas injected into a cylinder, wherein when the control unit switches from diesel mode to gas mode, the control unit increases the amount of gas injected to a first prescribed amount in the case of a switch start command, and simultaneously reduces the amount of petroleum injected to an equivalent of the amount of heat in the first prescribed amount of gas, after which the control unit performs a control so as to gradually increase the amount of gas injected and gradually reduce the amount of petroleum injected.
