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 ...

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 ...

The first production car engine with variable valve timing (VVT) came from Alfa Romeo in 1980. It was installed in the fuel-injected Alfa Romeo Spider. Before this, a few experimental systems existed, ...

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 ...

Though it's been called many things, the VTEC acronym stands for Variable Valve Timing and Lift Electronic Control. VVTLEC doesn't quite roll off the lips, but the adjectives one tends to spew out ...

Variable valve timing isn’t necessarily a new idea, but it is new to BMW motorcycles. With a freshly designed 1,254 cc two-cylinder flat engine, VVT is arriving in BMW bikes for the first time with an ...

At its most basic level, an engine is an air pump. Internal combustion engines breathe fresh air and expel wasted exhaust gases to make power. Something has to tell those intake and exhaust valves ...

An engine depends on perfect timing the same way a symphony depends on a conductor. Every valve opens at the exact moment it should, every piston moves in perfect rhythm, and everything stays ...

I was visiting Ford's Vehicle Operations (Pilot Plant) in 2002 with a Ford engineering buddy of mine when he decided to show me Ford's all-new F-150, which was scheduled to debut for 2004. There were ...
