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 ...

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 ...

Camshaft and valve timing events must surely seem like a bunch of monkey motion on the surface. However, there is a motive and madness to how camshafts are engineered and, more specifically, how ...

1. Net valve lift is the amount of lift (imparted to a valve) as measured at the camshaft lobe. 2. Valve duration is the period of time during which a given valve is off its respective seat and ...

If you're a car enthusiast, you've probably heard the term "VTEC" before, but you might not know what it means. If you don't, here's an explainer. But the way VTEC goes about switching cam profiles is ...
