摘要： In response to activation of a compression release brake when a motor vehicle having a turbocharged internal combustion engine is operating at some elevation above sea level and a turbocharger compressor is operating in a region of an operating map which is creating boost air in an engine intake manifold which would cause the compression release brake to decelerate the vehicle more slowly at that elevation than it would at sea level for the same operating conditions of the vehicle and engine other than altitude, the compression release brake decelerates the vehicle less slowly by causing an exhaust gas recirculation system to reduce at least one of a) mass of exhaust diverted to an intake system of the engine and b) cooling of the diverted exhaust.

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： An apparatus and method for varying a counter force to valve spring preload of a brake exhaust valve to undertake engine braking, includes a solenoid controlled hydraulic actuator. A control cylinder is arranged to move with a rocker arm and a control piston is arranged to slide within the control cylinder. During engine braking the control piston slides to press the valve stem to open the brake exhaust valve. An oil chamber is arranged above the control piston and is open into the control cylinder. A source of pressurized oil is selectably introduced into the oil chamber by the solenoid controlled hydraulic actuator to slide the control piston within the control cylinder to open and hold open the brake exhaust valve.

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： 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.

摘要： An engine controller causes a propulsion engine of a motor vehicle to be fueled in a fueling mode of operation and not to be fueled in a non-fueling mode of operation. A controlled device, such as a clutch or regulator, controls operation of a pneumatic compressor which forces compressed air into a storage tank. The controlled device is controlled according to a strategy which distinguishes between the fueling mode and the non-fueling mode for improving overall vehicle fuel economy.

摘要： When the difference by which pressure in an engine exhaust manifold exceeds pressure in an engine intake manifold becomes less than a selected difference while an intake valve operating mechanism is closing cylinder intake valves at a selected time in the engine cycle, while an EGR system is conveying the engine exhaust component of an air/exhaust mixture from an exhaust system to an intake system, and a certain quantity of NOx is present in engine exhaust entering the exhaust manifold, the quantity of NOx present in engine exhaust entering the exhaust manifold is reduced below that certain quantity by causing the intake valve operating mechanism to close the cylinder intake valves earlier in the engine cycle than the selected time.
