Video: Comparing Variable Valve Lift And Variable Valve Timing
Variable valve lift (VVL) and variable valve timing (VVT) are two of the most common dynamic valvetrain features found in modern commuter cars and even many of today’s performance cars. VVT has its roots in emissions control with some performance benefits and VVL was primarily designed for top end performance, but do you know how each system operates, what sets them apart and how they can further benefit an engine when combined?
Jason Fenske, a Mechanical Engineer and host of the YouTube channel Engineering Explained, and Charles Sanville, a Master Certified Volkswagen Technician and host of the channel Humble Mechanic, teamed up to present the facts about both variable valve lift and variable valve timing and their differences. While manufacturers have developed many different variations of VVL and VVT the end goal is still the same, and the 2.0-liter four-cylinder turbocharged engine used in the video above features the Audi Valvelift System (AVS).
