Abstract: A system and method of integrating an engine having dynamic skip fire control with an exhaust gas recirculation system in a turbocharged internal combustion engine is described. An engine control system determines an appropriate firing pattern based at least in part on a desired exhaust gas recirculation flow rate. Signals from sensors in the intake manifold and exhaust system may also be used as part of a feedback loop to determine a desired exhaust gas recirculation flow rate.

Abstract: An internal combustion engine system includes an engine with a plurality of pistons housed in respective ones of a plurality of cylinders. A valve train is provided for opening and closing intake and exhaust valves of the cylinders during nominal engine operations. The valve train is also configured for cylinder deactivation and to provide one or more selected lift profiles for opening and closing of the intake and/or exhaust valves.

Abstract: Intake manifold-cylinder head connectors and methods of assembling the same are disclosed. A distal jumper tube includes a distal jumper tube conduit with an upstream end having a first exterior engagement feature and a downstream end. A proximal jumper tube includes a proximal jumper tube conduit with an upstream end and a downstream end having a second exterior engagement feature. A middle jumper tube includes a middle jumper tube conduit with an upstream end having a third exterior engagement feature, and a downstream end having a fourth engagement feature. The first exterior engagement feature is removably coupled to the fourth exterior engagement feature, and the second exterior engagement feature is removably engaged to the third exterior engagement feature. The proximal jumper tube is in fluid receiving communication with an intake manifold conduit, and the distal jumper tube is in fluid providing communication with a cylinder head aperture.
