  • Engine intake system with modulated tuning
    Patent number: 4549506
    Abstract: Modulated tuning intake systems for multi-cylinder internal combustion engines are described wherein dual plenums are each connected to essentially half the engine cylinders and tuned to provide enhanced charging efficiency in a predetermined, normally lower, range of engine speeds. A controlled valved connector or tube is provided between the plenums to effectively modify or eliminate their separate character by joining them at other selected engine speeds, such as the middle and higher speed ranges, thus providing enhanced charging efficiency at these speeds and obtaining improved volumetric cylinder charging efficiency over all, or a major portion, of the engine operating speed range.

  • Selective asymmetric swirl intake port
    Patent number: 4539954
    Abstract: Cylinder intake charge swirl is accentuated by selectively directing flow past swirl generating vanes in the intake port which are closest to the cylinder wall and reducing the flow past swirl generating vanes furthest from the cylinder wall. This may be accomplished by utilizing asymmetrically variable swirl vanes arranged to reduce flow at lower engine loads through passages furthest from the cylinder wall and encourage flow through swirl directed passages closer to the cylinder wall.
