摘要： An engine assembly includes a cylinder head having an intake side and an exhaust side opposite the intake side. The cylinder head has an intake port, an exhaust port, and a combustion chamber in fluid communication with the intake port and the exhaust port. The engine assembly further includes a port fuel injector coupled to the cylinder head. The port fuel injector is disposed closer to the exhaust side than to the intake side of the cylinder head. Further, the port fuel injector is fluid communication with the intake port to allow fuel to be injected directly into the intake port. The engine assembly further includes a direct fuel injector coupled to the cylinder head. The direct injector is in fluid communication with the combustion chamber to allow fuel to be injected directly into the combustion chamber.

摘要： 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.

摘要： An internal combustion engine comprises a first engine bank and a second engine bank. A first intake valve is disposed in an intake port of a cylinder of the first engine bank, and is configured for metering the first flow of combustion air by periodically opening and closing according to a first intake valve lift and duration characteristic. A variable valve train control mechanism is configured for affecting the first intake valve lift and duration characteristic. Either a lift or duration of the first intake valve is modulated so as to satisfy an EGR control criterion.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A pushrod valvetrain combustion system assembly for an internal combustion engine includes a two-valve pushrod assembly and a cylinder top that forms a portion of a cylinder head. The cylinder top has a single intake port, a single exhaust port, a spark plug bore, and a fuel injector bore. The pushrod assembly includes an intake valve positioned in the intake port and an exhaust valve positioned in the exhaust port. The intake port and exhaust port are positioned adjacent each other and are positioned along an axis that intersects a center point of each of the ports. The intersecting axis is rotated relative to a centerline of the crankshaft of the engine, providing space for the spark plug bore and fuel injector bore to both be located in the cylinder top on a same side of the intersecting axis.
