In 1918 the Nobel family established the Nobel-Diesel company in Nynäshamn, Sweden. By 1921 it had built a 1,600 hp four cylinder two-stroke direct reversible Diesel engine. It had a fuel efficiency of over 80%, better than any other two-stroke engine. Many factories bought a license for this engine. E.g. Mirrlees, Bickerton and Day in the United Kingdom, Nydqvist and Holm in Trollhättan, Niigata Diesel, and Burgerhout. Nobel-Diesel itself closed down in 1925.
