Variable cam phaser Delphi Power Train

Variable cam phasing changes the timing of the lift event in a gasoline engine. It can be used to shift the intake cam, the exhaust cam, or both on dual overhead cam engines. This helps increase engine efficiency and, thus, improves idle stability while delivering more torque and horsepower. It also helps boost fuel economy and reduces hydrocarbon emissions.

The benefits of Delphi's variable cam phasers are application-specific and are derived by increasing volumetric efficiency, reducing pumping losses and in-cylinder internal dilution control associated with varying the cam timing.

Delphi has more that 75 years' experience in valve train systems and its high-quality conventional valve train products have earned industry-wide respect.
