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 ...

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, ...

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 ...

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 ...

Valve timing is the most important factor determining an engine's character. A good illustration of this is provided by the following curious historical fact. In 1947 the Standard Motor Company of ...

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, ...
