Abstract

Engine systems and methods improve emission control through the use of concurrent HCI and EGR. An engine system includes at least two cylinders. A fuel system intermittently supplies a first fuel stream to the first cylinder and a second fuel stream to the second cylinder. An intake system supplies combustion air to the cylinders. An exhaust manifold has one or more interior chambers through which the exhaust gas from the cylinders passes. An EGR circuit is connected between the exhaust manifold and the intake system and includes an EGR valve. A controller operates the fuel system to supply the first fuel stream to deliver fuel to the exhaust system while operating the fuel system to stop the second fuel stream from delivering fuel to the exhaust system, and to open, concurrently with operating the fuel system to supply the first fuel stream, the EGR valve to supply the exhaust gas to the intake system.
