The jargon goes well beyond just names. Car specs are full of abbreviations that may or may not have any meaning at first glance. And sometimes we get so used to seeing those abbreviations that we may ...

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 ...

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 ...

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, ...
