It looks to be a 4-cylinder inline, and if it's a two-stroke engine, I wonder what its intended application was. Certainly not aviation, at that point. (I was going to say that there were no 4-cylinder inline two-stroke motorcycles, but I looked around and found that in 1911 there was at least one company, Pierce, manufacturing them.) EDIT: now I see that the Pierce was not a two-stroke, despite what I had initially read.
