About Variable valve timing VVT :

In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems.

VVT Operation :

VVT systems are simple to diagnose. Most parts are non-serviceable and have integrated sensors. On a conventional engine, exhaust and intake valves are open or closed depending on the crankshaft and the pattern cannot be altered. With VVT, it is possible to have the timing altered to match the engine speed, torque requirements, and valve overlap. This increases both performance and fuel economy. Another great advantage of VVT is its ability to take some of the load off the crankshaft by opening the valve before the end of the combustion stroke. VVT systems have made Exhaust Gas Recirculation (EGR) valves obsolete. EGR valves put smog causing nitrous oxides back into the intake manifold. The VVT system controls the timing to leave inert gas in the chamber for the next combustion cycle, thus controlling the combustion temperature and the production of nitrous oxides.
