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 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 ...

Honda did not invent variable valve timing or variable valve lift. In fact, Cadillac had a driver-operated variable valve timing system in production in 1903, three years before Soichiro Honda was ...

Despite current efforts to revisit light-vehicle fuel economy standards enacted during the Obama administration, there have been no changes to the law, and there might not be for years, as the wheels ...

We’ve just heard that Piaggio Group, parent company to Aprilia, is working on a mechanical variable valve timing (VVT) system – and the first to reap the benefits of the tech will be none other than ...

The tough guy in you says to stab that cam in retarded a few degrees for maximum top-end horsepower, while your more practical alter ego suggests advancing it a hair for improved low-end torque and ...

Variable valve timing is one of those things expected of today's engines. Like fuel injection, aluminum cylinder heads or four- cylinder engines with 16 valves, dynamic camshaft manipulation is more ...

VTEC is an acronym for a variable valve-timing system used on Honda and Acura models since 1989. The full name is variable valve timing and lift electronic control, and the first U.S. model with VTEC ...

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 bike that won the title of “world’s fastest production motorcycle” at the turn of the century could soon sport a bit of tech that will support hi-rev performance at lower emissions… but at what ...
