ABSTRACT:
An internal combustion engine, especially of the two stroke cycle diesel type, has a turbocharger with a supplemental mechanical drive for maintaining a minimum speed ratio relative to engine speed, when exhaust energy is insufficient to provide a higher speed, so as to maintain adequate charging air for engine operation throughout the engine speed range. In order to provide more efficient operation during engine operation at idle and in a lower portion of the operating range where a reduced amount of charging air is adequate, a secondary lower speed ratio is provided by the mechanical drive system. A speed responsive clutch is included to disconnect the higher speed primary drive during engine operation in the lower speed range and permit operation at the more efficient secondary speed ratio.
