FUEL SUPPLY SYSTEM FOR LIQUEFIED GAS INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel supply system for liquefied gas internal combustion engine capable of suitably suppressing the deterioration in supplying precision of fuel according to the supply of gas phase fuel. SOLUTION: This fuel supply system for liquefied gas internal combustion engine comprises a liquid phase fuel supplying system for injecting and supplying liquid phase fuel in a fuel tank to an internal combustion engine 1 through a liquid phase fuel injector LIN, and a gas phase fuel supplying system for supplying gas phase fuel in the fuel tank through a gas phase fuel injector GIN. The inclusion of a gas other than fuel LPG in the fuel tank is monitored. When the fuel quantity required for the operation of the internal combustion engine 1 is a prescribed fuel quantity or more in the case where the inclusion of gas other than the fuel is confirmed, a minimum gas phase injection quantity of gas phase fuel by the gas phase fuel injector GIN is supplied to the internal combustion engine 1.
