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 ...
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 ...

What Was The First Engine To Feature Variable Valve Timing & Why Was It Such A Game Changer?
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 ...
The inlet and exhaust valve timing of a piston engine plays a large role in engine performance. Many modern automotive engines have some sort of variable valve timing, but the valves are still ...
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 ...
Without variable valve timing, these intake and exhaust valves would operate in the same manner regardless of the engine’s RPM (revolutions per minute) speed or the driving environment. This isn’t ...
Mitsubishi Innovative Valve timing Electronic Control (MIVEC) engine to power the production “i” car
August 5, 2005 Mitsubishi Motors Corporation (MMC) has developed two Mitsubishi Innovative Valve timing Electronic Control (MIVEC) aluminium cylinder block engines to power two new models slated for ...
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 ...
Mihai has even branched beyond the usual confines of an automotive writer from time to time, however, his heart is still close to anything car-related. He's most at home retelling the story of some ...
