Abstract:
1. An injector mounting structure for a V-type internal combustion engine in which an intake manifold is arranged in a V-bank formed between cylinders arranged on the respective sides so as to be inclined to form a V-shape for sucking air to the respective cylinders, comprising: a fuel supply pipe disposed in the V-bank and being oriented in parallel to a crankshaft and extending linearly; and a pair of injectors branched from two branch portions spaced apart from each other in the direction of an axial line of the fuel supply pipe into an inverted V-shape in a side view from a direction of the axial line of the fuel supply pipe and extending in parallel to each other and obliquely at an acute angle with respect to a segment connecting the two branch portions in top view; wherein the injectors are mounted by fitting respective distal end portions of the pair of injectors respectively to mounting holes formed on front and rear air-intake pipes on the respective sides of the intake manifold, wherein an intake channel of the front air-intake pipe has a length different from the length of an intake channel of the rear air-intake pipe.
