This movie shows the DWK M36 running after the second start after 15 years of standing still. As you can see it's a 3 cilinder four stroke engine with 120HP at 300 RPM from 1936. After the second world war, Deutsche Werke Kiel had to change their name into MAK.
This engine looks a bit like my MAN, the injector pumps are the same.
