Abstract
An intake manifold system for a V-type multiple cylinder engine comprising an upstream intake passage, a plenum intake chamber, an intake manifold and downstream intake passages. The upstream intake passage which is directly connected to a throttle body curves downwards towards the intake chamber while the downstream intake passages are connected to the upper end of the intake chamber by way of the intake manifold and after being curved in the shape of inverted letter U are connected to the intake ports of the engine. The intake manifold system as a whole can be accommodated within a gap defined between the two cylinder banks of the engine in a highly compact manner. The advantageous arrangement of the overall intake passage produces favorable ram effect and assures high volume efficiency particularly in low speed range of the engine.
