Schapiro engine
The Schapiro engine is a rotary piston engine concept developed by the mathematician Boris Schapiro. Schapiro came up with the concept at the end of the 1960s on behalf of the "Institute for Rare Earths" in what was then the USSR . Like the rotary piston Wankel engine (KKM 57) from 1957, the Schapiro engine is based on a rotating triangular piston with curved sides.
In 2003 , Schapiro presented the idea of a second shaft that serves as the discontinuous axis of rotation of a gear. As a result, the piston of the Schapiro rotary piston machine (RKM 03) makes one revolution around two shafts. The theoretical result is better contact between the piston flanks and the combustion chamber, which means that seals can be dispensed with. In contrast to the Wankel engine, which only has one shaft, it requires valves to control the gas exchange.
So far, no running engine has been demonstrated, car manufacturers rated the rotary piston machine (RKM 03) as "too expensive for the market".
