In an engine-starting and stopping system in a vehicle, a crank pulley for driving auxiliary parts by an endless belt is mounted at an end of a crankshaft protruding from a cylinder block of an engine, and a starter motor for cranking the crankshaft is accommodated in an internal space in the crank pulley. The starter motor includes a rotor having a permanent magnet fixed to an inner peripheral surface of a peripheral wall of the crank pulley, and a stator having a coil fixed to an outer surface of a chain cover. Thus, the starter motor for automatically carrying out the restarting of the engine after stopping of the engine can be laid out compactly.

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.

An exhaust reaction chamber for an internal combustion engine has an outer downstream chamber section surrounding and enclosing an inner upstream chamber section which receives exhaust gases from the engine. Intake mixture for the engine is heated by exhaust gases in the outer chamber section. A leak hole is provided in the inner chamber section for accelerating heat transfer to the intake mixture during warmup operation of the engine.
