ABSTRACT:
EGR induction supercharged or turbocharged internal combustion engine having EGR and EGR cooling in which EGR cooling is obtained through jacket water coolers and/or an air-to-air aftercooler. EGR induction is obtained via either low pressure (ambient) induction to the system intake, or via venturi or passive pump induction into the pressurized intake. Bypassing of the EGR cooler is used to reduce condensation and fouling in the EGR cooler and to provide warmer air to reduce light load and cold ambient hydrocarbon production. A passive or catalyzed particulate trap and crankshaft driven supercharger boosting system are provided to address engine response deterioration and particulate increase problems associated with EGR.
