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 ...

Once upon a time, picking a cam for a given engine combo was all about compromise: improve top-end power at the expense of low-end torque, run well at wide-open throttle but sacrifice idle stability ...

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 ...

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 ...

Valve overlap—that crucial interval when both the intake and exhaust valves are open, expressed in degrees of crankshaft rotation—is typically a fixed parameter and always a compromise. For example, ...

VTEC stands for Variable Valve Timing and Lift Electronic Control and represents a variable valve control system developed by Japanese car manufacturer Honda for its gasoline engines. The system was ...

Engines are complex bits of machinery. At their core level, yes, it's easy to understand what is happening. Air and fuel enter the engine where they are ignited and combustion occurs resulting in ...

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 ...
