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 ...

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 ...

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 ...

Brian Cooley is CNET's Editor at large and has been with the brand since 1995. He currently focuses on electrification of vehicles but also follows the big trends in smart home, digital healthcare, 5G ...

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 ...

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 ...

While the engineering community continues to explore the benefits of electric and hybrid vehicles—i.e., the environmental and renewable energy factors—the automotive market is still dependent on ...
