ABSTRACT:
This injector mounting structure has attained the reduction of the length of a fuel pipe, a total height of an engine and a distance between cam shafts. A fuel supply boss extends from the relative injector diagonally at a predetermined angle, and passes a position close to the cam shafts and then a position between cams mounted on these cam shafts, so that it becomes possible to minimize the total height of an injector body, and reduce the length of the fuel pipe to be connected to a fuel supply boss. The fuel supply boss is provided with an escape portion for preventing the fuel supply boss and cam shafts from interfering with each other, whereby the fuel supply boss and cam shafts may be disposed closer to each other. The distance between the cam shafts becomes shorter, and the shafts of the suction and exhaust valves can be disposed closer to each other as they are kept parallel to each other, the performance of even a miniaturized engine being not deteriorated.
