Here's what Mr Nicolas A Otto designed and got to work that evolved into the engines we have today.
As you look and watch, a couple points.
The power stroke was originally the weight of the piston and rack coming down ( weight and vacuum from fired hydrogen mixture cooling)
No spark plug. Ignition was a sliding block ( slide valve) that literally cut off a piece of the hydrogen flame and transferred it to the combustion chamber.
Engine speed is controlled by restricting the exhaust gases.
This engine is a replica built by Wayne Grenning
