Variable valve timing (VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems.
Variable valve timing (VVT) is a system for varying the valve opening of an internal combustion engine. This allows the engine to deliver high power, but also to work tractably and efficiently at low power. [1]
To give you an idea of just how quickly today’s engines move, here’s a glimpse into the N55’s operating strategy: Intake-valve timing: The BMW inline-six’s intake-camshaft phaser can shift the cam...
Few innovations under the hood have become as ubiquitous as variable valve timing. Automakers brag about it all the time, but seldom explain it. So Brian Coo...
Nowadays, the ‘VVL’ system is being increasingly used in combination with ‘Variable Valve Timing’ (VVT) systems to improve the performance. Additionally, this design also alters the lift (or travel) of the inlet valves along with valve timing depending upon the engine’s speed.
In this tech article HOT ROD provides a guide to variable valve timing (VVT) technology which can be found in most late-model performance engines and we explain how hot rodders can get the...
Variable valve timing (VVT) is a technology used in modern internal combustion engines to vary the timing of the engine’s valves. This technology allows for improved engine performance, fuel efficiency, and emissions control.
By using variable valve timing (VVT) technology it is possible to control the valve lift, phase, and valve timing at any point on the engine map, with the result of enhancing the overall engine performance. To get full benefits from VVT, various types of mechanisms have been proposed and designed.
Variable Valve Timing is a crucial technology in modern automotive engines, balancing the demands for power, efficiency, and emissions control. Understanding how VVT works can provide valuable insights into how your vehicle performs under different conditions.
Variable valve timing (VVT) allows for precise control of the opening and closing of internal engine valves while you drive. It’s used in modern engines to improve performance and fuel economy , while also reducing emissions.
