ABSTRACT:
An intake system of a V-engine provided with a surge tank arranged at a position higher than a cylinder head and divided in internal space into a top part and a bottom part. The surge tank has a plurality of intake tubes communicating the surge tank and intake ports, wherein intake tubes communicated with one cylinder bank of the V-engine are connected to the top part of the surge tank and intake tubes communicated with the other cylinder bank are connected to the bottom part of the surge tank. The surge tank is formed so that a front end of the top part is positioned further toward a rear side of the vehicle compared with the front end of the bottom part when the intake system is mounted to a V-engine mounted in the vehicle, whereby the height of the engine hood can be effectively lowered.
