PROBLEM TO BE SOLVED: To obtain a fuel supply equipment capable of generating swirl within a combustion chamber easily by decreasing the number of parts and simplifying the structure. SOLUTION: In a fuel supply equipment for an engine 6, a main body of an air assist injector 3 is disposed to be offset at 5 deg. clockwise with respect to the axial line X of an intake pipe 4 such that the respective jets from two fuel injection ports provided with the air assist injector 3 are offset with respect to the first intake valve 2 and the second intake valve 2A. As a result, one of two fuel injection ports is oriented to face the inner peripheral wall of the first intake port 1 and the peripheral edge of the first intake valve 2. The other one of the fuel injection ports is oriented to face the inner peripheral wall of the second intake port 1A and the peripheral portion of the first intake valve 2A. As a result, at intake process, the first and the second intake valves 2, 2A open. When the mixture is injected through two fuel injection ports upon each opening of the first and second intake valves 2, 2A, the resultant jet is formed into swirl flow, which further flows into a combustion chamber 8, where swirl is generated. |
