VARIABLE CAM PHASING TWO-STEP VALVE LIFT WITH CAM PHASING Variable cam phasing changes valve traintiming as engine operating conditions change. It shifts the intake cam, exhaust cam orboth, on dual overhead cam engines, for improvements in engine efficiency,idle stability, torque and horsepower, fuel economy and hydrocarbon emissions. This process can be fine-tuned to suit the personalities of individual vehicles.And the vane configuration offers pack- aging advantages for a variety of engineconfigurations.All in all, this is a high-performing systemat an attractive cost already the...

CylinderDeactivation Innovations in electronicshave allowed Delphi to develop an advanced cylinderdeactivation system. It is digitally controlled to selectivelydeactivate half of the engineגs cylinders under certaindriving conditions. The technology is designed to boostfuel economy by 89%. All the while, functioning so smoothly that the driver is unaware of its operation. >
