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： An engine control system coordinates control of a pressure regulating mechanism associated with a turbocharger turbine and control of a variable valve actuating (VVA) mechanism for expanding the range of possible exhaust gas recirculation rates over a large portion of an engine operating map to provide EGR rates which are greater than typical present-day levels while mitigating engine pumping losses by causing the turbocharger to operate with better efficiency in some regions of the map where it otherwise would not. Turbocharger efficiency is improved by controlling the VVA mechanism to set the timing of operation of its respective cylinder valves in accordance with a predetermined correlation of operating efficiencies of a compressor to timing of operation of respective engine cylinder valves, causing the compressor to operate at points of better efficiency than it otherwise would without use of VVA.

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.

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.

The braking control is configured to command the exhaust valve actuator to substantially open and substantially close the exhaust valve at least twice during each engine cycle, a first event and a second event, when the pressure within the exhaust manifold is greater than the pressure in the cylinder. The braking control can also command the exhaust valve actuator to substantially open and substantially close during a third event between the first and second events.
