摘要： The working fluid circuit of the present invention includes an exhaust gas passage through which exhaust gas under pressure flows from the internal combustion engine, a charge air passage, and a turbocharger. An exhaust gas recirculation passage extends between the exhaust gas passage and the charge air passage, but bypasses the turbocharger and provides a path for recirculating a predetermined amount of exhaust gas into the charge air passage in such a way that the exhaust gas and the charge air are mixed together. An intake passage provides intake air to the internal combustion engine. A single charge air cooler is operatively interconnected to and provides fluid communication between the charge air passage and the intake passage and acts to cool the mixed charge air and the recirculated exhaust gas prior to induction into the internal combustion engine through the intake passage.

摘要： An internal combustion engine block having a circumferential channel formed between the cylinder block and a cylinder liner, surrounding and adjacent to the high temperature combustion chamber region of the engine, to which coolant flow is diverted from the main coolant stream to uniformly and effectively cool this critical area of the liner. The high velocity flow of the main coolant stream, as it passes the end of the cylinder liner adjacent the combustion chamber, provides a reduced pressure head at the port interconnecting the outlet end of the circumferential channel with the main coolant stream. Channel entrance holes, located upstream at relatively stagnant regions in the main coolant flow, are at a higher pressure head than the channel exit port, thus inducing flow through the channel at a high velocity flow.

摘要： A viscous fluid fan clutch assembly for a vehicle includes an internally-mounted pump plate for separating a working chamber from a reservoir. A plurality of discharge orifices are provided in the pump plate to permit the return of fluid from a pumping chamber to the reservoir. A fluid discharge channel is provided for each discharge orifice to receive fluid exiting the pumping chamber and to direct the fluid to an inner portion of the reservoir. A check valve is provided at the discharge channel to prevent the flowback of fluid from the reservoir to the discharge channel, particularly when the clutch assembly is not in operation.

摘要： A fan clutch assembly for a vehicle includes a flexible, ferromagnetic valve plate for controlling fluid flow through a pump plate into a shear zone. When an electromagnetic coil is energized, the resulting flux deflects the valve plate away from the pump plate to open fluid gates in the pump plate. When the coil is de-energized, the valve plate returns to its original engagement position against the pump plate to close the fluid gates.

摘要： A fan clutch assembly for a vehicle includes a pump plate assembly for separating a receiving chamber from a reservoir, wherein the receiving chamber receives fluid from a shear zone. The pump plate assembly includes an orifice for permitting the passage of fluid from the receiving chamber to the reservoir. A check valve is provided at the orifice to control the flow of fluid and permit only one-way flow from the receiving chamber into the reservoir. The check valve eliminates the migration of fluid through the orifice from the reservoir into the receiving chamber.

摘要： An engine working fluid circuit for a turbocharged internal combustion engine that employs exhaust gas recirculation. The working fluid circuit includes an exhaust gas passage, a charge air passage, and a turbocharger operatively driven by the exhaust gas flowing from the internal combustion engine and acting to provide pressurized air to the charged air passage. An exhaust gas recirculation passage extends between the exhaust gas passage and the charge air passage bypassing the turbo charger and providing a path for recirculating a predetermined amount of exhaust gas into the charge air. A single charge air cooler is also included that has a first manifold assembly, a second manifold assembly, and a plurality of cooling passages disposed therebetween. The cooling passages act to cool the mixed charge air and recirculated exhaust gas prior to induction into the internal combustion engine. A flow valve is operatively disposed between the first manifold assembly and the second manifold assembly, and is movable between open, bypass, and reverse positions to control the flow of the mixed charge air and recirculated exhaust gas through the cooler. The open position provides forward flow through the cooling passages; the bypass position provides flow that bypasses the cooling passages; and the reverse position provides a reverse cleaning flow through the cooling passages.

摘要： A viscous fluid clutch having a bimetallic coil includes an insulating retainer. A body of the retainer is mounted between the coil and an outer surface of the clutch housing. A flexible tab on the retainer is placed between a first end of the coil and a slot on the clutch housing to provide an interference fit and eliminate the need for adhesives. The body inhibits the transfer of radiant heat emanating from fluid inside the clutch to the coil. Preferably, the body and tab are integrally formed.
