Abstract: A dual core exhaust gas recirculation cooler includes a cooler housing having an EGR inlet, first and second EGR outlets, a cooling circuit extending from a coolant inlet through the cooler housing to a coolant outlet, a first EGR circuit core extending from the EGR inlet to the first EGR outlet, and a second EGR circuit core extending to the second EGR outlet from the EGR inlet or the first EGR outlet. A first EGR valve is configured to selectively couple the first EGR circuit core to a return passageway. A second EGR valve is configured to selectively couple the second EGR circuit core to the return passageway. The EGR valves are configured to selectively flow exhaust gas through the cooler housing within either the first EGR circuit core only or within both the first EGR circuit core and the second EGR circuit core.

Abstract: An internal combustion engine includes a block containing a crankshaft and a crankcase surrounding the crankshaft, a plurality of combustion chambers configured to receive an intake fluid and generate exhaust fluid, an exhaust circuit configured to direct the exhaust fluid away from the plurality of combustion chambers, an intake circuit configured to supply the intake fluid to the plurality of combustion chambers, a turbine disposed in the exhaust circuit and having a turbine shaft configured to be driven by the exhaust fluid, a crankcase ventilation circuit configured to direct crankcase fluid away from the crankcase, and a pump disposed in the crankcase ventilation circuit and having a rotor configured to be driven by the turbine shaft to propel the crankcase fluid through the crankcase ventilation circuit.

Abstract: One or more techniques and/or systems are disclosed for a vibration mitigation device. The vibration mitigation device can comprise a shell forming a hollow body that is configured to house a coupled wiring connector and a connector block. The shell can comprise first shell section and second shell section that are operably engaged with each other, and engaged with a vehicle component to which the connector block is engaged. The shape and sizing of the shell and its hollow body allow for a compressive force to be applied to the coupled connectors, to mitigate vibration between the two connectors during use.

Abstract: An internal combustion engine includes a crankcase with a plurality of piston-cylinder arrangements and a valve head positioned above the crankcase at least in part containing a valve train. The internal combustion engine further includes a head cover coupled to the valve head and having a blowby outlet and a baffle positioned between the head cover and the crankcase and defining an oil passage internal to the baffle. Engine oil circulates through the oil passage of the baffle to transfer heat to blowby gas flowing from one or more of the plurality of piston-cylinder arrangements before exiting the valve head through the blowby outlet in the head cover.

Abstract: An exhaust manifold for use with an internal combustion engine, the exhaust manifold including a body, one or more fluid passageways defined by the body, a valve in fluid communication with at least one of the one or more fluid passageways, the valve being adjustable between an open configuration and a closed configuration, a mounting bracket supported by the body, and an actuator in operable communication with the valve and configured to adjust the valve between the open and closed configurations, and wherein the actuator is coupled to the mounting bracket.

Abstract: An engine gas valve with a valve housing manifold with at least one flow passage and an annular clutch body arranged within the valve housing manifold. A drive shaft is arranged such that at least a portion of the drive shaft is positioned concentrically within the clutch body. A first valve element is supported on the drive shaft to rotate with the drive shaft within the at least one flow passage and a second valve element supported on the clutch body within the at least one flow passage. An actuator is coupled to the drive shaft to pivot the drive shaft between a first state in which the first and second valve elements are closed, a second state in which the first valve element is open and the second valve element is closed, and a third state in which the first and second valve elements are open.
