Document Type and Number:
Japanese Patent JP6175190
Kind Code:
B2
Abstract:
A water supplying step of supplying water to a liquid-fuel channel of a nozzle is executed during a liquid fuel supply state in which only liquid fuel is supplied to the nozzle; a post-switch water purging step of supplying water to the liquid-fuel channel of the nozzle is executed during a gas fuel supply state in which only gas fuel is supplied to the nozzle; and a mid-switch water purging step of supplying water to the liquid-fuel channel of the nozzle is executed during a fuel switching state which is a state of transition from the liquid fuel supply state to the liquid fuel supply state. A second flow rate of water supplied in the mid-switch water purging step is lower than a first flow rate of water supplied in the water supplying step. In the post-switch water purging step, water is temporarily supplied at a third flow rate which is higher than the second flow rate.
