SIDE STRUCTURE OF ENGINE

Removal and breakage of fuel piping during a vehicle front collision is prevented for an engine mounted longitudinally in an engine compartment. Embodiments include a side structure of the engine having an alternator in front of an intake manifold and fuel piping behind the intake manifold so as to extend in the vertical direction. The intake manifold includes a plurality of independent intake pipe portions each having one end portion connected to one side of the engine in a vehicle width direction, and a surge tank portion to which the other end portions of the independent intake pipe portions are connected. As seen from the rear side, a portion of the fuel piping closer to the surge tank portion is located closer to the one side of the engine in the vehicle width direction than the surge tank portion.
