PURPOSE:To reduce noise of combustion by providing an airflow regulating lattice in a ventilating tube near the connecting part of a vaporizing cylinder and the ventilating tube. CONSTITUTION:The airflow regulating lattice 11 is provided in the ventilating tube 4 near the connecting part 10 of the vaporizing cylinder 1 and the ventilating tube 4. The airflow regulating lattice 11 is constituted so as to have the configuration of a convex lense substantially and a holding hole 12 penetrating through the center of a fuel nozzle 6. According to this method, pressure loss at the center of the ventilating tube 4 is increased, therefore, a difference of flow speed distribution between the central section of the ventilating tube 4 of combustion air and the section near the side wall of the same is decreased and whereby the sound of injection may be reduced.
