Zusammenfassung:	PURPOSE: To prevent the contraflow of fuel to an assist air supply passage. CONSTITUTION: Intake pressure on an upstream side adjacent to an injection port of a fuel injection valve 7 is introduce to an assist air injection port from an air outlet 96a for assist air through a flexible tube 16 on which a one-body valve 15 is arranged, from an intake pressure inlet 14. The intake pressure applied to the assist air injection port from the portion immediately below is cancelled. The contraflow of the fuel to the assist air supply passage due to the intake pressure is thus prevented for avoiding bad influence on an air-fuel ratio.
