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 ...

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 ...

Somewhere there's a perfect balance between peak horsepower, low-speed response, reduced emissions, and something you can afford. Variable valve timing and lift have done their part in getting us all ...

Without variable valve timing, these intake and exhaust valves would operate in the same manner regardless of the engine’s RPM (revolutions per minute) speed or the driving environment. This isn’t ...

Though it's been called many things, the VTEC acronym stands for Variable Valve Timing and Lift Electronic Control. VVTLEC doesn't quite roll off the lips, but the adjectives one tends to spew out ...

Manufacturers like to use a lot of acronyms on their cars. Variable valve lift (VVL) and variable valve timing (VVT) are two of the most popular ones. These systems sound pretty similar, but what do ...

Alanson Partridge Brush. Remember that name. Because it was according to his patents that Cadillac put into production something that Honda and Alfa Romeo took decades to match. Mr. Brush's invention?

Engines are complex bits of machinery. At their core level, yes, it's easy to understand what is happening. Air and fuel enter the engine where they are ignited and combustion occurs resulting in ...
