ABSTRACT:
To balance ignition retard for reduction in exhaust and increase in exhaust gas temperature at a start of cooling, and increased output under a full open condition. There are provided an upward spray that forms airflow toward an electrode portion of an ignition plug at a start of cooling, a central spray oriented toward the electrode portion of the ignition plug by the airflow by the upward spray, and lateral sprays that prevent fuel from adhering to a wall surface under a full open condition and form uniform air/fuel mixture.
