Enthusiasts who work on these engines still face the same challenges described decades ago: sourcing apex seals, managing oil-gas mixtures, and finding that elusive perfect ignition timing.
The story of the is a tale of postwar innovation, the pursuit of mechanical simplicity, and the harsh realities of high-RPM engineering. It is a saga covering small, powerful rotary engines—most notably the KM37 and KM48 —which Fichtel & Sachs brought to market in the 1960s and 70s as a compact alternative to conventional piston engines.
