Hoemo was the first diesel engine that Hans Hoernlein designed after he moved to West Germany from Suhl East Germany.

After a run of about 30 engines Hans Hoernlein altered his design. For production reason he fastened the Cylinder muff and sleeve with three long M3 x 20 mm screws. Later the engine was called Taifun Standard 2.5 cc
