Provided is a mixed fuel supply system configured by providing a DME tank (a liquefied gas fuel storage tank) 14 which stores DME and a DME supply path (a liquefied gas fuel supply path) 15 which supplies the DME in addition to a configuration of a light oil supply system 8 of a conventional technique, in which the DME supply path 15 is connected to a transfer path 7 between a feed pump 4 and a fuel injection pump 6a, and the DME supply path 15 includes a flow regulating valve 16, in which a supply amount Q DME of the DME is regulated to be approximately 10% of a total supply amount Q fuel of a mixed fuel in weight ratio by the flow regulating valve 16, and the mixed fuel mixed in the transfer path 7 is transferred to the fuel injection pump 6a, and then injected from injectors 5. This makes it possible to supply the mixed fuel obtained by mixing the liquid fuel and the liquefied gas fuel to an internal combustion engine by utilizing the fuel supply circuit and the fuel injection circuit for the liquid fuel as they are without making significant modifications. |
