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 ...

In order to set a stage for what follows, let's first revisit some of the fundamentals involved in how valve timing relates to power output. And to further clarify how "power" is defined in the ...

Variable valve timing is one of those things expected of today's engines. Like fuel injection, aluminum cylinder heads or four- cylinder engines with 16 valves, dynamic camshaft manipulation is more ...

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 ...

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 ...
