PURPOSE:To largely reduce graphite contained in exhaust gas by providing a gasification chamber communicated to a combustion chamber in response to the action of a valve body, a fuel feed means feeding a liquid fuel to the gasification chamber, and a heating means arranged in the gasification chamber. CONSTITUTION:A main combustion chamber A and a pre-combustion chamber B are communicated via a jet nozzle 8. A heater 18 is formed in a gasification chamber C. An activation chamber D having a ring-like hollow section is formed with the shaft section 15a and valve body 15b of a gasifying valve 15 and a valve receiving member 10. The liquid fuel is gasified in the gasification chamber C by heating it with the heater 18, and an air-fuel mixture is formed. Then, the mixture is guided to the combustion chambers A, B by opening the valve body 15b. Accordingly, graphite contained in the exhaust gas can be largely reduced. |
