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 ...

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 ...

Every aspect of an engine is a compromise: torque for horsepower, efficiency for emissions, performance for fuel economy, compression for octane tolerance. During the evolution of the internal ...

Do you have warning lights, misfires, and/or starting trouble? If so, you car's timing belt could be faulty -- it's time to ...

This collection of cam-related phenomena is intended to take you beyond the degree-it-in and set-the-valve-lash plateau. In concert with what you may already know about camshaft types, selection, and ...

The hunt for efficient engine valve technology can be a never-ending journey into cam timing, various combustion cycles, and lift and duration adjustments. For that reason, some companies believe ...

The truly cool thing about internal combustion engines is there's always another creative way to skin the power/efficiency/emissions cat. Fiat's Multiair technology is a prime example. Even though ...

While the 5.3L LS4 V8 was the first car engine to feature Active Fuel Management (cylinder deactivation) technology, it was not Flex Fuel capable and did not have variable valve timing. As mentioned, ...
