BW153/3
Bolinder started building oil engines in about 1894. It initially manufactured four-stroke engines but a change was made to two-stroke operation early on, and thereafter was to be almost exclusively used by the company. By 1918, over 600,000 bhp had been sold in various engine types and configurations, making Bolinder one of the leading engine makers in Europe, although its location in Sweden restricted its export potential. In 1902 FA Rundlof invented a 2-stroke hot bulb engine, the design of which he passed to Bolinder. This engine was used as a 15hp model in the motors of pairs of narrowboats and a 9hp model in single motors also as 20hp and 30 hp models in tugs. The company is still in existence in Sweden.
