variable cam timing
- Variable camshaft timing allows the valves to be operated at different points in the combustion cycle, to provide performance that is precisely tailored to the engine’s specific speed and load at that instant
- The power train control module (PCM) directs solenoids to alter the oil flow in the hydraulic cam timing mechanism, which rotates the camshafts in relation to their drive sprockets
- The unit can shift between fully advanced and fully retarded in milliseconds
- The result is enhanced efficiency under low-load conditions, such as at idle or highway cruising, and increased power for brisk acceleration or times of high demand
- Variable valve timing reduces pumping losses, the work required to pull air in and push exhaust out of the cylinder.
