By Julius de Waal

Julius’ drawings for the Poppin flame licker, or flame gulper or,  vacuum engine  from an original design by  Dr J R Senft.

Photos are of the engine built by Donald Hamilton of Bristol MES.

The engine operates by the flame and associated hot air being drawn into the cylinder on the outward stroke through the hole in the end. The flap valve then closes and the power stroke is generated by the vacuum of the cooling gases.

Only change made to the drawing by Donald was that the flame needed to be positioned closer to the end of the cylinder.
