Abstract
A method of controlling engine internal exhaust gas recirculation may include estimating a flow restriction through a diesel particulate filter in an exhaust system of an engine assembly and adjusting a backpressure control valve in the exhaust system downstream of the diesel particulate filter based on the flow restriction. A controlled amount of internal exhaust gas recirculation may be provided to the engine assembly based on adjusting the backpressure control valve.
