Abstract:
To secure a capacity of a surge tank part while constituting a suction/exhaust device compact in a size.SOLUTION: An intake manifold 24 has a surge tank part 25, and a communication pipe 26 for making the surge tank part 25 and an intake port communicate with each other. A relay exhaust pipe 42 for relaying the exhaust port and an exhaust emission control device 43 is arranged in a region between the surge tank 25 and the exhaust emission control device 43 in a vehicle width direction, and in a vehicle vertical direction, the relay exhaust pipe extends upward from a position lower than the intake manifold 24. The relay exhaust pipe 42 extends upward in a state that at least a part of the relay exhaust pipe 42 is overlapped on the surge tank part 25 when viewed along the vehicle width direction. After the surge tank 25 extends toward a side opposite to the exhaust emission control device 43 in the vehicle width direction with an introduction port being a connection part connected with the communication pipe 26 as a starting point, the surge tank is bulged toward a front side in the vehicle fore-and-aft direction.SELECTED DRAWING: Figure 4
