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 ...
Straight variable valve timing systems have no effect on lift or duration. Meanwhile, variable valve lift setups have a margin of control on lift, duration, and timing. Most, but not all, systems are ...
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 ...
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 ...

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, ...
Valve overlap—that crucial interval when both the intake and exhaust valves are open, expressed in degrees of crankshaft rotation—is typically a fixed parameter and always a compromise. For example, ...
It's springtime! Time to start working on your project car, learn a new wrenching skill, discover what everything is under the hood (and how it works), or just spruce up your daily driver. All month, ...
Everybody kind of knows what it is and has a picture in their mind of what a camshaft looks like, but maybe not a full understanding of what it really does or the technological advances that ...
