摘要： A system and method for managing the characteristics of engine oil in a lubrication system for an internal combustion engine is disclosed. Generally speaking, the method includes the steps of determining a target viscosity for the engine oil based on engine speed and engine load, determining a working viscosity which may be directly measured or determined based on engine oil temperature and engine oil type, comparing the target viscosity to the working viscosity, deriving a target engine oil temperature, and directing engine oil to one of an oil cooler, an oil heater, or neither when and until the target engine oil temperature is achieved. The oil viscosity management system includes an engine lubrication system having a volume of engine oil, a cooler coupled to the lubrication system, a heating mechanism also coupled to the lubrication system, a valving system for directing flow of the oil and coupled to each of the lubrication system, the cooler and the heating mechanism, a signal generator for generating a signal based on operational parameters of the engine, and an estimator for controlling the valving system in response to the signal.

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 method for dislodging exhaust gas deposits from an exhaust gas recirculation (EGR) cooler (26) associated with an engine includes the steps of providing at least one on-board gas source (S) for providing a gas (G) at a superatmospheric pressure, and placing the EGR cooler in fluid communication with the gas source through a supply conduit (44, 144). The supply conduit (44, 144) includes at least one valve (V) that is selectively operable to a closed condition closing the supply conduit and to an open position opening the supply conduit. The method also includes the step of operating the at least one valve (V) from the closed condition to the open condition to allow the superatmospheric gas (G) to flow through the supply conduit (44, 144) to the EGR cooler (26).

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.

摘要： While an engine is miming with all engine cylinders being fueled, a historical record of engine output torque and engine speed is compiled. When the historical record discloses a change in engine operation from a relatively greater output torque and engine speed to a relatively lesser output torque and speed, fueling of at least one engine cylinder ceases while engine output torque and engine speed remain substantially unchanged at the relatively lesser output torque and speed by continuing fueling of other engine cylinders and by causing at least one mechanism to control the timing of operation of cylinder intake and exhaust valves of the at least one engine cylinder to substantially minimize pumping loss attributable to the at least one engine cylinder.
