Abstract

An internal combustion engine (20) has a supercharger (50) for providing boost pressure tailored to engine speed. The supercharger (50) is controlled or specifically designed such that boost presure for engine speeds above a predetermined level is equal to or less than the maximum permissible boost and boost pressure for engine speeds thereabove is less than maximum permissible boost. The supercharged engine has high, low engine speed torque while maintaining nearly naturally aspirated power at higher speeds. The design requires few modifications to the naturally aspirated base engine.
