Abstract
An engine system (20) includes an intake system (26) through which charge air enters combustion chambers, and an exhaust system (28) that includes a CDPF (34), through which products of combustion pass to the surrounding atmosphere. A throttle valve (36) is located in The exhaust system (28) downstream of both the CDPF (34) and the turbocharger turbine (30). An EGR flow path for recirculating exhaust gas from the exhaust system to the intake system includes an EGR valve (48) for controlling EGR flow. The EGR flow path is connected to the exhaust system upstream of the throttle valve and downstream of both the CDPF and the turbine, and to the intake system upstream of the turbocharger compressor Valves (36, 48) are under coordinated control provided by an engine control system (24) for selectively restricting the respective valves to attain desired EGR flow.
