Description:
This engine was modelled after a design by Armin
de Vries. The ultimate size was determined by the 205 mm diameter flywheels
and the 50 mm hydraulic cylinder I had stashed away. Therefore, my version
turned out to be two thirds larger than the original.
The increased displacement is responsible for the peculiar sound of the running
engine, especially at low rpm. The rpm can be controlled by adjusting the length
of the wick of the alcohol burner.
