Abstract: An automobile vehicle overhead camshaft system includes multiple camshafts individually having multiple sliding camshaft barrels. Opposed ends of the camshaft barrels individually have a zero-lift lobe. Multiple intake valves are operated by a first one of the camshafts and multiple exhaust valves are operated by a second one of the camshafts. Multiple actuators operate during a deceleration cylinder cut-off (DCCO) mode to slidably displace the camshaft barrels to position the zero-lift lobe of predetermined ones of the multiple sliding camshaft barrels into contact with at least one of: all of the intake valves; or all of the exhaust valves.

Abstract: An automobile vehicle engine exhaust system with integrated exhaust gas recirculation portion includes a cylinder head having a first exhaust passage internal to the cylinder head. The first exhaust passage is split within the cylinder head into a dedicated exhaust passage opening out of the cylinder head via a dedicated exhaust port, and an exhaust gas recirculation (EGR) exhaust passage opening out of the cylinder head via an EGR exhaust port. A valve assembly is operated to open one of the dedicated exhaust port or the EGR exhaust port while closing the other one of the dedicated exhaust port or the EGR exhaust port.

Abstract: A method for operating an exhaust gas recirculation system using rationality diagnostics for an automobile vehicle includes: estimating an oxygen storage content (OSC) of a catalytic converter of a vehicle; comparing an amount of oxygen stored in the catalytic converter to an OSC threshold; initiating a closed oxygen storage control (COSC) event for a predetermined one of multiple cylinders of an engine of a vehicle if the OSC threshold is met or exceeded, the COSC event targeting a rich air-fuel equivalence ratio (EQR) for the predetermined one of the multiple cylinders; and directing a fuel injector communicating with the predetermined one of the multiple cylinders to operate the predetermined one of the multiple cylinders at the rich EQR.

Abstract: Flexible fluid connection systems are provided with misalignment management, vibration attenuation and compact packaging for a variety of applications. A fluid connection system includes a component that operates using a fluid. The component defines a surface and a passageway containing the fluid and opening through the surface. A fluid line is configured to convey the fluid relative to the component. A connector is made of a flexible material and is connected with the component and with the fluid line. The connector is positioned against the surface and has an end spaced away from the surface through which the fluid line is received.

Abstract: A vehicle engine exhaust system with integrated exhaust gas recirculation (EGR) includes an exhaust manifold having multiple exhaust ports including a first exhaust port and a second exhaust port. The first exhaust port and the second exhaust port receive exhaust flow from a common exhaust split upstream of the first exhaust port and the second exhaust port. A valve assembly has a first butterfly valve positioned in the first exhaust port and a second butterfly valve positioned in the second exhaust port. A shaft is positioned within the exhaust manifold commonly connecting the first butterfly valve to the second butterfly valve to simultaneously rotate the first butterfly valve and the second butterfly valve.

Abstract: An intake manifold of an automobile vehicle includes a manifold body connected to a cylinder head. A runner is in communication with the cylinder head. A plenum is in communication with the runner. An inner dividing wall is positioned between and partially separates the runner and the plenum while allowing communication between the plenum and the runner over a dividing wall end of the inner dividing wall. An orifice opening extends through the inner dividing wall providing a drain path from the plenum to the runner. The orifice drains a fluid collecting in the plenum to the runner.

Abstract: A method of operating an engine having an intake manifold, an exhaust manifold, a crankshaft, a plurality of working cylinders each having at least one intake valve and at least one exhaust valve, and an exhaust gas recirculation conduit providing fluid communication between the intake manifold and the exhaust manifold. The method includes: while the engine is operating, in response to a no engine torque request, deactivating a number of the working cylinders such that none of the deactivated working cylinders are fired and no air is pumped through the deactivated working cylinders as the crankshaft rotates, operating at least one of the plurality of working cylinders that is not deactivated to pump air through the non-deactivated working cylinder, and controlling gas flow through the exhaust gas recirculation conduit to circulate air pumped through the non-deactivated working cylinder to the intake manifold.

Abstract: A multi-port exhaust gas diverter valve disposed within a linkage of an exhaust manifold for selectively diverting an exhaust gas generated by an internal combustion engine to one or more of a turbocharger system, an exhaust gas recirculation system, and an emissions control system. The diverter valve includes an inlet port for receiving an exhaust gas from the exhaust manifold and a plurality of outlet ports. A rotatable valve sleeve having an open end and a slot opening is co-axially disposed within a cylindrical chamber defined by the valve body. The open end of the valve sleeve is in continuous fluid communication with the inlet port. The valve sleeve is selectively rotatable to align the slot opening with at least one of the plurality of outlet ports such that the valve sleeve provides fluid communication between the inlet port and the at least one of the outlet ports.

Abstract: A refrigeration power system for cooling a storage compartment in a vehicle includes a power source independent of a vehicle battery. The power source provides power to a refrigeration unit that includes a variable speed compressor. The refrigeration power system determines available power and varies the speed of the compressor accordingly to provide a lesser amount of cooling at start-up or when the available power value is less than a required power value. The power system operates the variable speed compressor at the required power value when the available power value is large enough to provide a cooling capacity so that the storage compartment obtains a pre-selected temperature. Power sources, and alternate power sources, include a vehicle generator, a shore power supply, a battery bank and a vehicle battery provided on the vehicle.
