摘要： A method of cooling exhaust gas (F) from an engine in an EGR cooler (10) for recirculation to the engine includes the steps of transporting the exhaust gas from the engine to a core assembly (22) disposed inside a single housing assembly (20), and dividing the housing assembly into at least a first cooling volume (42) of the EGR cooler (10) and a second cooling volume (44) of the EGR cooler (10). The core assembly (22) extends at least partially into the first cooling volume (42) and the second cooling volume (44). The method also includes the steps of introducing a first cooling fluid (CF1) into the first cooling volume (42), and introducing a second cooling fluid (CF2) into the second cooling volume (44). The exhaust gas (F) is transported from the core assembly (22) to the engine.

摘要： A circuit for cooling exhaust gas being recirculated through an EGR system (36) of an engine (10) from an exhaust system (20) successively through first and second heat exchangers (38, 40) to an intake system (16) for entrainment with intake air. Each heat exchanger has a respective coolant inlet through which liquid coolant enters and a respective coolant outlet through which liquid coolant exits after having absorbed heat from recirculated exhaust gas. The circuit has a third heat exchanger (32) to which coolant coming from the outlet of one of the first and second heat exchangers rejects heat, and parallel branches (84, 86) through which coolant enters the inlet of the other of the first and second heat exchangers. One of the parallel branches has a fourth heat exchanger (34) to which coolant flowing through that branch rejects heat, and one or more devices (50, 50A) for controlling the quantity of coolant flowing through each branch.

摘要： A first loop contains engine coolant passageways (28, 30) and a first radiator (34). A second loop contains a first EGR cooler (48). A third loop contains a second EGR cooler (50), a second radiator (36), a charge air cooler (26LP), a first valve (66), and a second valve (64). Valve (64) apportions coolant flow entering an inlet (64A) to parallel flow paths, one including second radiator (36) and the other being a bypass around radiator (36). The apportioned flows merge into confluent flow to both an inlet of charge air cooler (26LP) and a first inlet (66B) of valve (66). Valve (66) has an outlet (66C) communicated to an inlet of second EGR cooler (50). The first condition of valve (66) closes a second inlet (66A) to coolant flowing toward both the second inlet (66A) and inlet (64A) while opening inlet (66B) to outlet (66C). The second condition of valve (66) opens second inlet (66A) to coolant flowing toward second inlet (66A) and inlet (64A) of the valve (64) while closing first inlet (66B) of valve (66) to outlet (66C) of valve (66).

摘要： A system for driving an EGR stream for an engine includes an exhaust gas turbine, a main compressor and a supplemental EGR compressor. The turbine drives the main compressor to pressurize intake air and drives the supplemental EGR compressor to pressurize an EGR exhaust gas stream to be introduced into the intake air system. A supplemental EGR compressor takes suction of exhaust gas downstream from the turbine. A three-way valve proportions exhaust gas between the engine exhaust gas discharge conduit and the suction of the supplemental EGR compressor. The turbine drives a shaft and the main compressor and the supplemental EGR compressor are driven by having corresponding compressor wheels fixed onto the common shaft.

摘要： An expansion tank (10) for a vehicle cooling system (18) of an engine using a liquid coolant (16) includes a tank body (12) defining a first volume (V1) containing coolant (16), wherein the coolant defines a variable coolant elevation level (CEL) within the tank body. The tank body (12) also defines an upper volume (20) containing air. A bladder (14) is disposed in the tank body (12) and defines a second volume (V2) containing air. The bladder (14) includes a flexible membrane (36) actuated by an actuator (46). When the engine is stopped or is below a predetermined temperature, the flexible membrane (36) is moveable to a first position (FP) which lowers the coolant elevation level (CEL), and when the engine is started or reaches a predetermined temperature, the flexible membrane (36) is moveable to a second position (SP) which raises the coolant elevation level. A communicating line (38) is in fluid communication between the upper volume (20) and the second volume (V2) to fluidly communicate air therebetween.

摘要： A heat exchanger having a modified header design for absorbing high thermal loads, is described. The heat exchanger includes a housing having an interior space, a core within the interior space of the housing, the core comprising a plurality of flow passages, and a header positioned at an end of the housing and in communication with the core, wherein the header includes a thermal absorbing formation. The thermal absorbing formation may take the form of a continuous raised rib around an inner circumference of the header. The raised rib absorbs excess heat and reduces thermal strain on the heat exchanger.

摘要： An engine braking system includes a turbocharger having a turbine and a compressor. An exhaust manifold includes a first pipe for channeling a first portion of the engine exhaust and a second pipe for channeling a second portion of the engine exhaust. The first and second pipes are connected to an inlet of the turbine. A cross pipe, as part of an exhaust gas recirculation (EGR) conduit, is open between the first and second pipes and at one end to the remaining portion of the EGR conduit. A valve can be arranged within the cross pipe and ca be operable in a first mode of operation to block flow between the first and second pipes and allow flow between the first pipe and the remaining portion of the EGR conduit and to allow flow between the first and second pipes and the inlet of the turbine. The valve is operable in a second mode of operation to allow flow between the first and second pipes, and to reduce or block flow between the second pipe and the turbine inlet.
