Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

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 ...

Have you ever heard of the Silent Knight? It was a unique engine that ditched noisy valves for a weirder, quieter, and more ...

Desmodromic valvetrains allow for higher revs without needing to worry about valve float. So why do automakers not often use ...

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 ...

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 ...

A radical Maserati engine aimed to outperform rivals with sheer innovation. Instead, it hit a critical barrier that explains ...
