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.

摘要： A method of controlling a variable valve actuation system for an internal combustion engine having a plurality of cylinders, each of the plurality of cylinders having a variable valve actuator and in-cylinder pressure sensor is provided. Output of an in-cylinder pressure sensor is monitored at a predetermined crank angle Θp with an electronic control module. The output of the in-cylinder pressure sensor of the monitored one of the plurality of cylinders at the predetermined crank angle Θp is compared to a stored threshold value for in-cylinder pressure at the predetermined crank angle. A variable valve actuator is adjusted to adjust a crank angle Θc corresponding to when an intake valve of the monitored one of the plurality of cylinders closes when the output of the in-cylinder pressure sensor of the monitored one of the plurality of cylinders does not correspond to the stored threshold value.

摘要： A mechanism (40) for enabling an engine cylinder valve (18) to close at various times during engine cycles has a hydraulic actuator (58) and a control valve (60) controlling the hydraulic actuator a) to constrain a pivot axis of a valve rocker (52) against relocation while the cylinder valve is being forced increasingly open, and b) to release the constraint after the cylinder valve has been forced open for enabling the pivot axis to relocate so that the intake valve can close early thereby providing early IVC. A hydraulic snubber (64) snubs closing motion of the cylinder valve through a scheduling geometry to a hydraulic accumulator (62). The control valve opens to the accumulator to allow the rocker pivot axis to relocate and provide early IVC and closes to return the pivot axis to a location that doesn't provide early IVC.

摘要： A method of setting actuator position of a variable geometry turbine linked to drive a compressor for a compression ignition engine using exhaust gas recirculation. The method includes detecting an engine transient event; determining current mass air flow through the compressor and exhaust temperature; resetting variable geometry turbine position to maximize mass air flow through the compressor; adding the maximum allowable quantity of fuel; determining exhaust temperature increase; adjusting exhaust pressure to allow an increase in mass air flow and exhaust temperature; and returning to the resetting step until a limit is reached.
