Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

Most modern gasoline and diesel-powered engines found in the cars and trucks seen on today's roadways rely on the four-cycle-engine principles developed in the late 1800s by Nikolaus Otto, Gottlieb ...

There have been many engine valve designs since the dawn of the internal combustion engine. What made poppet valves stick? (See what we did?) There were many other designs and some, like the sleeve ...

Automobiles were still in their relative infancy in 1905, but they had been growing more popular for years. There was a problem, though: they were extremely noisy. One cause of the noise were the ...

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 ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.
