More Information
Summary:An internal combustion engine system having reduced high speed emissions comprising an exhaust driven supercharger having turbine pressure dependent control means for regulating turbine pressure and turbine speed to a substantially constant value to produce a decreasing compressor pressure profile with increasing engine speed and to reduce mass air flow through the engine during high speed operation, thereby reducing engine emissions and improving durability.
