PURPOSE:To secure the sufficient quantity of gasificated fuel as well as to make an arrangement compact by supplying fuel in a liquefied gas container in a state of liquid to a mixing chamber via a primary pressure regulator, and thereby permitting a pipe connecting the liquefied gas container to the primary pressure regulator to go around the heating section of an engine. CONSTITUTION:When an engine 7 is started with a cock 17 opened, liquid fuel at the bottom section of a liquefied gas container 27 is sucked in through a fuel suction pipe 25, a check valve 20, a valve opening mechanism 23, the cock 17, a pipe 18, a heater 19 and a pipe 20 so as to be gasificated by outside temperature. Gasificated fuel in the primary pressure regulator 32 is sucked in a venture 7 through a passage 4a, it is subsequently sucked in a cylinder 9 together with air from an air purifier 2 via an intake air port 6, it is then burned within the cylinder 9, so that a piston 10 is thereby reciprocated while exhaust gas is exhausted out of an exhaust port 13 to a muffler 15. When the engine 7 is started, the heater 19 is heated by exhaust temperature, liquefied fuel flowing from the liquefied gas container 27 to the primary pressure regulator 32 is thereby gasificated by the heater 19 so as to be stored in the primary pressure regulator 32, so that it is sucked in the cylinder 9 as required by the engine. |
