Variable valve timing (vvt) is a clever piece of automotive technology that optimizes engine performance and allows for better fuel efficiency in vehicles This is done by altering the camshaft profile, either mechanically, hydraulically, or electronically. It works by continuously (variably) adjusting the timing of the valves for better fuel economy, emissions, and power output.

Vvt is a system designed to adjust the timing of an engines valves to optimize performance and lower emissions throughout the engines entire operating range
When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains.
Here's an example of how variable valve timing works — if the vvt increases the valve duration of the exhaust valve, then more exhaust is expended from the cylinder. Discover how variable valve timing (vvt) technology improves your car engine performance, fuel efficiency, and power output Learn the basics and benefits explained simply. So, variable valve timing (vvt) adjusts the opening times and lift of the valves, to suit all operating conditions
This ensures ideal charge cycles, within a wide range of engine speeds and loads Fuel consumption and emissions are reduced, while torque and smoothness are increased. Variable valve timing is a system used in internal combustion engines to adjust the operation of the valves
