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 timing belt is one of those components most drivers never think about—until the engine suddenly stops running. Mechanics ...

The hunt for efficient engine valve technology can be a never-ending journey into cam timing, various combustion cycles, and lift and duration adjustments. For that reason, some companies believe ...

This collection of cam-related phenomena is intended to take you beyond the degree-it-in and set-the-valve-lash plateau. In concert with what you may already know about camshaft types, selection, and ...

Do you know what a timing belt or a timing chain is and what they do? Could you find them on your vehicle's engine if you had to? If you answered no, don't sweat it. Both are buried behind a lot of ...

Despite current efforts to revisit light-vehicle fuel economy standards enacted during the Obama administration, there have been no changes to the law, and there might not be for years, as the wheels ...

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 (VVT) and variable valve lift (VVL) have very similar names, both referring to variable valve performance. Does that mean that they are basically the same thing? The are most ...

Three and a half years of engineering have brought this beast to life with direct injection, variable valve timing, and way ...
