Bronvoll engine?

[FatBear]

Hi,
An ad appears in Boats & Harbors for a Norwegian trawler built in 1914. The ad says it is powered by a 2 cylinder Bronvoll engine. I have not heard of this engine and can find no reference to it with a Google search. Does anyone know anything about this engine? Was it misspelled or is it just that obscure?
Thank you,

--Brian

Bronvoll should be spelled Brunvoll. Brunvoll was one of the better known norwegian manufactorers of semidiesel engines, building engines from 1912 to about 1965. You can visit www.semidiesel.com (http://www.semidiesel.com) for more history on norwegian semidiesel engines (the site is written in norwegian, though !).

Sorry, correct adress: www.semidiesel.no (http://www.semidiesel.no)
