What is Variable Valve Timing and how does it work?

Understanding Variable Valve Timing Systems In traditional engine designs, engineers faced a constant trade-off between performance, fuel economy, and emissions. One of the biggest challenges was the camshaft—a fixed component that controlled valve lift, duration, and timing. A camshaft optimized for high power output often led to rough idling and increased emissions at low RPMs. Conversely, a camshaft designed for smooth operation and fuel efficiency would limit high-end performance. This meant every engine was a compromise, performing adequately across all power bands but excelling in none. Enter Variable Valve Timing … Read More
