Abstract:

A system and method are provided to control the power output, fuel efficiency and gas emissions of an internal combustion engine using an exhaust gas recirculation system. A recirculation loop containing a heat exchanger and an accumulator is installed between the exhaust ports and intake ports of the cylinders of the internal combustion engine. Diverter valves are used to control the amount of exhaust gas directed into the recirculation loop and the proportion of exhaust gas entering the intake ports. Controlling the amount of re-circulated exhaust gas and proportion of exhaust gas in the intake ports thereby controls the power output of the internal combustion engine.
