Variable valve timing is one of the most effective ways to increase an engine’s power output without having to make it bigger or add more components. The valves of an engine are what let air in and exhaust gases out of the combustion chamber, and reconfiguring the intervals during which the valves … See more Engines without variable valve timing open and close valves at the exact same rate all the time, but as the engine builds up revs, more air is necessary in order to produce more power. Engines with fixed valve timing produce less … See more In engines with VVT, you’ll find a VVT actuator fitted to the camshaft that carries out the mechanics when it comes to modifying the valve timing. This actuator has small oil … See more In most VVT systems, while the intake manifold camshaft simply alters valve timing, the exhaust camshaft actually has two different cam profiles for each set of exhaust valves.
