ABSTRACT:
A gasoline engine system includes a gasoline engine, a throttle valve for metering a supply of combustion gas fed to the engine, and a source of metered fuel injected into the combustion gas mixture. The throttle valve includes an inlet air supply line, a recirculating exhaust gas supply line, and an output line. Air entering through the inlet air supply line and exhaust gas entering though the recirculating exhaust gas supply line mix to create a combustion gas mixture of air, fuel and exhaust gas before exiting the output line. A body is actuatable to control a proportion of air versus recirculating exhaust gas in the combustion gas mixture.
