ABSTRACT:
An intake system for use in a V-shaped engine includes an intake manifold which is disposed in a valley defined between a pair of cylinders, disposed in a substantially V-shaped arrangement, and which includes a pair of intake pipe assemblies having a plurality of intake pipes coupled at their one end to the cylinders, respectively, and a surge tank which is flange-coupled commonly to the other end of the intake pipe assemblies. In the intake system, each of the intake pipe assemblies and the surge tank is formed from a synthetic resin, and a spacer made of a metal, and having clamping bolts integrally provided thereon, is interposed between each of the flanges of the intake pipe assemblies and a flange of the surge tank. Each of the flanges of the intake pipe assemblies and the flange of the surge tank are coupled to each other by the clamping bolts inserted through the flanges of the intake pipe assemblies. Thus, it is possible to provide a reduction in weight of each of the intake pipe assemblies and the surge tank and moreover to moderate the concentration of stress and assure sealability.
