摘要： Interference between an intake manifold and a fuel pipe during a vehicle front collision is prevented in an engine which is longitudinally mounted in an engine room. A vehicle component is arranged on the front side of an intake manifold, and a fuel pipe is arranged on the rear side of the intake manifold. The intake manifold includes a mounting portion on the intake-air downstream end side of a plurality of independent intake pipe portions and connects each of the plurality of independent intake pipe portions to a portion of the engine on one side of the engine in the vehicle width direction. The mounting portion has a front-side mounting portion relatively positioned on the front side and a rear-side mounting portion relatively positioned on the rear side, and the rear-side mounting portion has a higher rigidity than the front-side mounting portion.

摘要： Interference between an intake manifold and a fuel pipe during a vehicle front collision is prevented in an engine which is longitudinally mounted in an engine room. A vehicle component is arranged on the front side of the intake manifold, and the fuel pipe is arranged on the rear side of the intake manifold. The intake manifold includes a plurality of independent intake pipe portions arranged side by side in the vehicle front-rear direction which branch for each of the cylinders of the engine; and a plurality of coupling portions that each couple adjacent independent intake pipe portions to each other in an integral manner A first coupling portion of the plurality of coupling portions positioned on the frontmost side has a lower rigidity than a third coupling portion of the plurality of coupling portions positioned the rearmost side.
