This aircraft engine comes directly from the certificated JAR22, sect. H IIIB version. It is a four stroke, air cooled, over-head valve, carbureted, inverted in-line four-cylinder. The engine is designed for powered gliders or for other light aircraft which can employ its small size. Its cross section enables desirable shaping of the cowling which consequently reduces the frontal drag of the aircraft. The engine is equipped with a carburettor, fuel supply is secured by a dual-diaphragma 2M-50 fuel pump plus an electric pump for back up. The ait-fuel mixture is preheated in the distribution-manifold by exhaust heat tranfer. Dual ignition with two magnetos and two separate sets of plugs. Dry-sump oil system with separate oil tank outside the engine. 

The electric starter, supplied by 12V DC has 1,0 kW power output. The engine is also equipped with a generator. The 12 V AC-generator supplies the system with 160 W nominal power. Ram air for engine cooling enters through intake opening on the left hand side of the engine front cowling, is directed around heads and cylinders by sump and baffling and then exhausted through the opening in the right-hand engine cowling.
