The Second World War: 1940-1945

During the war, considering the reduced possibilities for sales and trading, the company continued its activities. The company supported the fishing fleet, which was a matter of survival for the hungry crowd. The transport over rivers also had to continue as it was the best way for transportation of wheat and potatoes. As the production level was low anyhow, a lot of time was available for research and design for the post-war future. Two prototype medium-speed engines, a 2-cylinder and a 3-cylinder engine were available at the end of the war. They were built in trawlers, the ideal test for an engine, as nowhere else such severe working conditions were encountered. The new engines, 4-stroke single acting, developed during the war under the code name DU (Diesel Universal) are the base for many designs and concepts of ABC engines later on.
