Abstract
A power train has an engine, such as a multi-valve, double overhead camshaft engine, which is equipped with a mechanical supercharger and an intercooler, and a transmission operationally coupled to the engine. The engine, which is adapted to provide the maximum output according to the maximum supercharge volume of the mechanical supercharger, has an intake valve closing time which is retarded more than 65 degrees of a crank angle after bottom dead center on an intake stroke and a maximum speed for the maximum output of less than 6,000 rpm. The transmission provides, in its highest gear, the power train with a total reduction ratio in a relatively small range of 2.1 to 2.8.
