Motorenbau Alfred Berning was located in Schwelm, Westfalen, Germany. There is very little company history available. The company's name is on the list of German companies that used slave labour during World War II, so they must have been in existance then.

I know of the 4 stroke petrol and diesel engines that Berning made from 1951 till 1965. The single and twin cylinder petrol engines were made under license of Universal of Switzerland (Universal AG Oberrieden/Zurich ?).

In 1957, W.E. Meyer of The Pennsylvania State University writes in a report on European engine production:
Among 4 cycle gasoline engines, that by Berning is noteworthy in that it combines a one-piece crankcase with a crankshaft that forms a permanent assembly with the connecting rod. Main and connecting rod bearings are of the antifriction type. The rod has a solid big end and the crankshaft is built up, so that two parts must be assembled in the factory. In order to insert the crankshaft-rod assembly into the case, the latter is open on one side toward the top. The cylinder base rests not only on the case, but also on the endplate which carries one of the three cylinder mounting studs. The rated BMEP of the Berning engine is about 100 psi. It has side-valves and a compression ratio of 5.6:1.


The Berning 4-cycle diesel claims a specific weight of 16.3 lb/hp. This figure is comparable to that of 2-cycle engines of the same size and remains remarkable even if some allowance is made for differences in flywheel weight and auxiliary components, etc. The engine has 21 cu. in. displacement and delivers 7 hp at 3000 rpm. This corresponds to a BMEP of 88 psi, a quite respectable figure in view of the small cylinder size and the high speed. A turbulence chamber cast into the aluminium head is used. Note the cooling fins around the injection nozzle.


See my Berning models page for the engines they produced.

See the Berning engine register for a list of all known remaining Berning engines worldwide.
