A system and method for dissipating vehicle under hood heat accumulated during stationary engine operation at high load or RPM and/or under high temperature ambient conditions is installed in a vehicle having an engine positioned within an engine compartment, and a cooling fan selectively driven by way of a fan clutch. The system includes a controller connected to the engine and to the fan clutch. The controller determines whether the period of stationary engine operation occurs at or above a threshold engine load or RPM, at or above a threshold engine operating temperature, at or above a threshold ambient temperature, and/or for or longer than a threshold stationary engine operation duration. If so, the at least one controller increases a low idle set point of the engine and commands the fan clutch to engage or remain engaged for a cool-down period following the period of stationary engine operation.

An exhaust gas recirculation system for a gasoline engine, including an exhaust gas line, which can be connected to an exhaust manifold of the gasoline engine and which includes a turbine, and an inlet line, which can be connected to an intake manifold of the gasoline engine and which includes a compressor. A main exhaust gas catalytic converter is provided in the exhaust gas line, and at least one exhaust gas recirculation line_I is provided which branches off from the exhaust gas line upstream of the turbine and opens into the inlet line downstream of the compressor. At least one particle filter_I is provided which is placed in the exhaust gas recirculation line_I or in the exhaust gas line upstream of the exhaust gas recirculation line_I. The particle filter_I has a 3/Ox coating, and at least one cooler_I is provided within the exhaust gas recirculation line_I downstream of the at least one particle filter.

An exhaust gas control valve of an engine, which includes a plurality of engine exhausts ports, a catalytic converter, a plurality of combustion chambers, and an Exhaust Gas Recirculation (EGR) line, includes: a valve body having an inflow port communicating with only some of the plurality of engine exhaust ports, an exhaust port communicating with the catalytic converter and a recirculation port communicating with the EGR line; and a valve flap assembly rotatably installed at the valve body to block one of the exhaust port and the recirculation port while opening the other of the exhaust port and the recirculation port.

An engine system includes an internal combustion engine with two sets of cylinders, a turbocharger, two exhaust conduits providing fluid communication between the turbocharger and an exhaust of the cylinders, and an exhaust gas recirculation system including a recirculation valve. Two proportional exhaust valves are adapted to control a flow of exhaust gas in the two exhaust conduits. An actuator includes an output component operating the recirculation valve and the two exhaust valves. In a neutral position, the two exhaust valves are open and the recirculation valve is closed. A first movement of the output component, from its neutral position towards a first position, open the recirculation valve and close a first of the two exhaust valve. A second movement, from the first position and in the same direction as the first movement, close the second exhaust valve and hold open the recirculation valve and closed the first exhaust valve.

A system includes an internal combustion engine having a number of cylinders, with at least one of the cylinders plumbed to have a complete recycle of the exhaust gases from the cylinder. The system further includes the completely recycled cylinder having an EGR stroke cycle, and the non-recycled cylinders of the engine having an exhaust stroke cycle. The system includes the EGR stroke cycle being distinct from the exhaust stroke cycle. An amount and composition of the exhaust gases from the recycled cylinder are distinct from the amount and composition of the exhaust gases from the non-recycled cylinders, at least at certain operating conditions of the engine.

An exhaust manifold for use with an internal combustion engine having a first cylinder and a second cylinder. The exhaust manifold includes a first fluid path having a first inlet in fluid communication with the first cylinder of the internal combustion engine and a first outlet, a second fluid path having a second inlet in fluid communication with the second cylinder of the internal combustion engine and a second outlet, and a valve adjustable between a first configuration, in which the first fluid pathway is in fluid communication with the second fluid path, and a second configuration, in which the first fluid pathway is not in fluid communication with the second fluid pathway.
