    Abstract: A cylinder head defines an inlet port having an exit. A valve seat insert defines a seat cut surface that is disposed adjacent to the exit of the inlet port. A cross section of the inlet port parallel to a centerline of the inlet port defines a long turn edge of the inlet port cross section. The long turn edge of the inlet port cross section defines a flow path trajectory of the inlet port. The seat cut surface and the flow path trajectory are substantially aligned to extend the flow path trajectory of the long turn edge of the inlet port cross section across the seat cut surface.

    Abstract: An engine assembly includes an intake assembly, a spark-ignited internal combustion engine, and an exhaust assembly. The intake assembly includes a charge air cooler disposed between an exhaust gas recirculation (EGR) mixer and a backpressure valve. The charge air cooler has both an inlet and an outlet, and the back pressure valve is configured to maintain a minimum pressure difference between the inlet of the charge air cooler and an outlet of the backpressure valve. A dedicated exhaust gas recirculation system is provided in fluid communication with at least one cylinder and with the EGR mixer. The dedicated exhaust gas recirculation system is configured to route all of the exhaust gas from the at least one cylinder to the EGR mixer for recirculation back to the engine.

    Abstract: A method of reducing warm-up time of an aftertreatment device and a vehicle system for the same are disclosed. Fuel is injected into a plurality of cylinders of an internal combustion engine which is controlled, via a controller. The fuel in a first subset of the plurality of cylinders is combusted to produce a first exhaust product having excess fuel. The fuel in a second subset of the plurality of cylinders is combusted to produce a second exhaust product having excess air. The first exhaust product is expelled through a turbocharger and a valve is actuated to route the second exhaust product away from a dedicated EGR system and downstream from the turbocharger. The excess fuel of the first exhaust product and the excess air of the second exhaust product are mixed downstream from the turbocharger to create an exothermic reaction that produces heat to warm up the aftertreatment device.

    Abstract: An exhaust gas recirculation system includes an engine defining first and second combustion chambers, wherein a fuel is combustible to produce a combustion gas. The system includes an intake manifold disposed in fluid communication with the first and second chambers, an exhaust manifold disposed in fluid communication with the second chamber, and an exhaust gas recirculation conduit disposed in fluid communication with the first chamber and configured for directing the gas from only the first chamber to the intake manifold. The system includes a bypass valve transitionable between a first position wherein the conduit is disposed in fluid communication with the exhaust manifold such that the gas flows from the first chamber to the exhaust manifold, and a second position wherein the conduit is not disposed in fluid communication with the exhaust manifold such that the gas does not flow from the first chamber to the exhaust manifold.
