Coolspring Spotlight: Bisschop-type Sombart gas engine

The circa-1883 5 MP Sombart features a crankshaft that is offset from the cylinder, as well as an ignition flame jet. The engine operated on the non-compression 2-stroke cycle invented by Jean Joseph Étienne Lenoir, who manufactured some of world’s first successful gas engines around 1860.
