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 ...

The Mitchell mechanical Variable Valve Timing (VVT) system is described. The way in which it exploits variable angular velocity to change valve timing is explained. The system was used in a programme ...

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 ...

VTEC is an acronym for a variable valve-timing system used on Honda and Acura models since 1989. The full name is variable valve timing and lift electronic control, and the first U.S. model with VTEC ...

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 ...
