Big Bridge -Bohm created a really big engine by putting 4 engines all inline. That is a total of 8 pistons (4 displacer, 4 power pistons). Each engine has its own burner. An truly impressive sight to see.

This very well made German Stirling runs using the supplied burner. Just add methylated spirits (denatured alcohol), light and place under the Stirling engine. Wait a short while for engine to heat up and give the flywheel a flick. It will burst into life and get up to an impressive speed. You can then throttle the speed by sliding back the burner or removing. Product is supplied assembled.
