PURPOSE:To aim at reducing the manufacturing cost of an engine in which solenoid injection valves are disposed in a plurality of intake-air passages opened to combustion chambers, by incorporating the plurality of fuel injection valves integrally with each other, and by disposing magnetic shield layers between the fuel injection valves. CONSTITUTION:In an engine provided with an intake-air passage 11 in which first branch passes 13a, 13b shunt out from an introduction passage 12, a two fuel injection valves 17a, 17b which are disposed in a housing 16 are disposed upstream of a shunt section from which the two fuel injection passages 13a, 13b shunt. The housing 16 is formed therein with a fuel supply hole 18 and two storage holes 19a, 19b orthogonal to the hole 18, a rectangular cross-sectional shape air-hole (magnetic shield layer) being formed between the storage holes 19a, 19b. The magnetic shield layer 25 shields magnetism generated from solenoids 21a, 21b of the fuel injection valves 17a, 17b, thereby it is possible to prevent the fuel injection valves 17a, 17b from magnetically interfering with each other. |
