  • Intake system for an internal combustion engine with a supercharger
    Patent number: 5448982
    Abstract: An intake system includes a supercharger for use with a power train. The power train includes a transverse engine and a transmission disposed transversely behind the engine. The engine has first and second rows of cylinders. Cylinders in each row are intended not to be fired one after another. The first and second rows of cylinders are offset sideways relative to each other. The intake system has an individual downstream intake part, downstream from the supercharger supported by the power train, for each row of cylinders. The individual downstream intake port includes a branch intake passage, branching off downstream from the supercharger and supported by the power train, and an inter-cooler disposed in the branch intake passage. One of the inter-coolers is located on a front side of the engine, and another of the inter-coolers is located above the transmission.
