Split engine control system with exhaust gas recirculation |
摘要 |
Disclosed is a split engine control system wherein the intake manifold is segmented by a shut-off valve into a first chamber portion leading to a first group of cylinders and a second chamber portion leading to a second group of cylinders. During periods of relatively low load, the cylinders of the second group are deactivated and the shut-off valve is closed to isolate the second chamber from the first chamber to cut off air supply to the deactivated cylinders. Exhaust gases are recirculated through the deactivated cylinders so that their pumping loss is minimized. A pressure detector is provided to detect a pressure difference which might develop between the first and second chambers during the partial cylinder operation to control the flow rate of the recirculated gases until the pressure difference reduces substantially to zero.
