How Variable Valve Timing Works

Here's how the Variable Valve Timing System Works on a car's engine. The four-stroke internal combustion engine consists of gasoline-rich air entering the cylinder in the intake stroke, compressed, then ignited to push the piston down to rotate the crankshaft in the power stroke. The piston then returns to the top pushing the exhaust gases out the valves, only for the cycle to be repeated over again. Variable valve timing optimizes fuel economy, thermal efficiency and emissions. An oil activated cam-phaser actuator is controlled by the ECU through an oil control valve. Oil pressure is sent through the VVT gear to fill up cavities to advance or retard timing. A closed loop control system utilizing the cam and crank position sensors is formed to ensure optimal timing by the ECU for either more power, or less emissions. In this video, the engine from an Infiniti G35 (VQ35DE) is taken apart to explain the components of the variable valve timing system, including the oil control valve, camshaft bearing caps, timing tensioner, engine head, valves, camshaft and pistons. Make sure you change your engine oil frequently!
