Abstract:
To provide a side part structure of a multi-cylinder engine capable of suppressing breakage of a fuel pump arranged behind an intake manifold even when the intake manifold moves to a rear side of an engine room upon vehicle front collision.SOLUTION: To a side surface of a multi-cylinder engine, an intake manifold having a surge tank 111 is attached. Under a rear portion 111c of the surge tank 111, a high-pressure fuel pump 20 and a cover 21 covering the front side and upper side of the high-pressure fuel pump are arranged. A center portion 111a of the surge tank 111 bulges downward, and is configured by an inclined surface where an outer surface behind a bulging lower end portion raises backward. A part of the high-pressure fuel pump 20, in back view, overlaps with the center portion 111a. On an outer surface of the surge tank 111, a plurality of vertical ribs Rv extending in a fore-and-aft direction in an area from a place near the high-pressure fuel pump 20 in the rear portion 111c to the center portion 111a is formed.SELECTED DRAWING: Figure 4
