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 ...

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 ...

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 ...

The heart of most vehicles today, the internal combustion engine has advanced significantly over its century long history. This series outlines some of the key innovations in engine technology before ...

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, ...

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 constant ...

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 ...
