Old hit-n-miss engine?

I do believe what you said is indeed what he called it. Since I didn't know what that meant, I just latched onto the description of what it's for --- a grist mill for grinding corn into meal.

It's actually quite clever.

The engine has a (usually centrifugal) limiter, that keeps the exhaust valve open and inlet valve closed if the engine is running fast enough.

In that case the engine basically just pumps air, but delivers no power and also uses no fuel.

When the engine speed drops enough, the mechanism disengages and the engine makes a full power cycle again.

This kind of mechanism is kind of making a comeback in (rediculously overpowered) modern cars where say 4 out of 8 cilinders can be disabled to save fuel.
