摘要： An engine assembly includes an engine block having a first bank of cylinders and a second bank of cylinders. A crankshaft is supported by the engine block and is configured to be driven by torque due to combustion energy in the first and second banks of cylinders. A first set of valves is operable to control air flow into and out of the first bank of cylinders. Camshafts driven by the crankshaft are operatively connected to the first set of valves to control opening and closing of the first set of valves. A second set of valves is operable to control air flow into and out of the second bank of cylinders. A controller is operatively connected to the second set of valves and is configured to vary at least one of lift, duration, and timing of the second set of valves based on commanded torque at the crankshaft.

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 integrated exhaust manifold for use with an internal combustion engine and dual scroll turbocharger. The integrated exhaust manifold includes a first exhaust passageway fluidly connected between a first pair of piston cylinders and the dual scroll turbocharger for transporting exhaust gas from the first pair of piston cylinders to a first input of dual scroll turbocharger. The integrated exhaust manifold includes a second exhaust passageway fluidly connected between a second pair of piston cylinders and the dual scroll turbocharger for transporting exhaust gas from the second pair of piston cylinders to a second input of the dual scroll turbocharger. The second exhaust passageway is fluidly independent from the first exhaust passageway and the first and second exhaust passageways are positioned to define a septum area therebetween. A cooling system having a septum cooling jacket is use to cool the septum area between the first and second exhaust passageways.

摘要： A secondary air injection or SAIR system is illustrated and described which includes a first air injection path defined by in part by a lower ditch formed in the head mounting surface of the cylinder block, and a second air injection path defined in part by a second ditch formed in the block mounting surface. The cylinder head gasket is used to separate and seal the first ditch from the second ditch. The first and second air injection paths are separate and isolated from one another such that secondary air may be selectively introduced through the first air injection path into the first exhaust leg and selective introduced through the second injection path into the second exhaust leg independent of the first air injection path.

摘要： A fuel control module controls fuel injection of an engine based on a predetermined lean air/fuel ratio. The predetermined lean air/fuel ratio is fuel lean relative to a stoichiometric air/fuel ratio for the fuel. A cylinder control module selectively deactivates opening of intake and exhaust valves of M cylinders of the engine to increase removal of nitrogen oxide (NOx) from exhaust. M is an integer greater than 0 and less than a total number of cylinders of the engine. The fuel control module further: disables fueling of the M cylinders while opening of the intake and exhaust valves of the M cylinders is deactivated; and, while fueling of the M cylinders is disabled and opening of the intake and exhaust valves of the M cylinders is deactivated, controls fuel injection of other cylinders based on a predetermined rich air/fuel ratio that is fuel rich relative to the stoichiometric air/fuel ratio.
