<p>PURPOSE: To enable accurate ignition by feeding back air in a fuel filter to a fuel tank utilizing a solenoid valve for the removal of air in the fuel filter to prevent failure in ignition during the initial igniting operation. CONSTITUTION: Receiving a control signal from a control means 40, a valve drive means 80 drives or controls solenoid valves 7 and 9 to control a circulation path of a combustion fuel to be supplied from an electronic pump 5. The valve drive means 80 is provided with first and second valve drive parts 81 and 82. The first valve drive part 81 drives or controls the first solenoid valve 7 to spray the combustion fuel being pumped by the electronic valve 5 under the control of the control means 40 into a vaporization chamber. The second valve drive part 83 drives or controls the second solenoid valve 9 which feeds the combustion fuel being pumped by the electronic pump 5 back to a fuel tank under the control of the control means 40 to remove air in a fuel filter.</p> |
