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 ...

Engines are complex bits of machinery. At their core level, yes, it's easy to understand what is happening. Air and fuel enter the engine where they are ignited and combustion occurs resulting in ...

The Mitchell mechanical Variable Valve Timing (VVT) system is described. The way in which it exploits variable angular velocity to change valve timing is explained. The system was used in a programme ...

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 ...

A flexible concept for fully continuous variable cam timing (VCT) is presented. The system has been introduced in volume production for both intake and exhaust phasing applications. This paper ...

BorgWarner, a global product leader in delivering innovative and sustainable mobility solutions, has solidified an agreement with Stellantis to supply its 50 mm variable turbine geometry (VTG) ...

It seems like every major automaker these days is using tricks like variable-valve timing – often in conjunction with forced induction – to eke better efficiency out of their engines while still ...

July 22, 2008 The concepts of drive-by-wire, steer-by-wire and brake-by-wire were initially eyed with much suspicion by automotive aficionados – how could a computer possibly hope to do a better job ...
