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 ...

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, ...

Once upon a time, picking a cam for a given engine combo was all about compromise: improve top-end power at the expense of low-end torque, run well at wide-open throttle but sacrifice idle stability ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

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 ...

The problem is as old as the internal combustion engine itself: Static valve timing is always a compromise. Figures that produce good power at lower engine speeds aren't ideal for higher-rpm operation ...
