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, ...

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 ...

Mazda might have already confirmed a rotary engine as a range extender for the MX-30 electric crossover, but CarBuzz has now uncovered unique details about the specifics of this compact rotary engine ...

The language of import performance can be strange. Sometimes it's a verbal stew of numbers and letters--RX-8, NSX, and MR2, for example--that seem randomly tossed together. At other times it adopts ...

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 ...

Every engine has a means of coordinating the timing between the valve train and the rest of the engine. Some engines use a timing chain and some a timing belt. A timing belt has the relatively ...

An engine's health depends on several key measures and functions. For example, air and fuel need to be present in the correct quantities, coolant is required to keep the engine operating at a safe ...

You just put your new crate engine together and your adrenaline is pumping. Pump the throttle, turn the key, and… the thing runs like a total dog. It idles fine, but as soon as you step on the ...

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 ...
