It's springtime! Time to start working on your project car, learn a new wrenching skill, discover what everything is under the hood (and how it works), or just spruce up your daily driver. All month, ...
Somewhere there's a perfect balance between peak horsepower, low-speed response, reduced emissions, and something you can afford. Variable valve timing and lift have done their part in getting us all ...
Every aspect of an engine is a compromise: torque for horsepower, efficiency for emissions, performance for fuel economy, compression for octane tolerance. During the evolution of the internal ...
Without variable valve timing, these intake and exhaust valves would operate in the same manner regardless of the engine’s RPM (revolutions per minute) speed or the driving environment. This isn’t ...
Most modern variable valve-timing (VVT) systems use a cam phaser that rotates the position of each camshaft relative to the timing chain. Think of making a record turntable go faster or slower by ...
Manufacturers like to use a lot of acronyms on their cars. Variable valve lift (VVL) and variable valve timing (VVT) are two of the most popular ones. These systems sound pretty similar, but what do ...

What Is Variable Valve Timing, And How Does It Work?
There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...
