Reminds me of an engine I saw at an old equipment show. Two cylinder
diesel engine mounted on a dedicated lowboy trailer. It was about ten
feet tall with built in blow torches for each head. Had an auxiliary two
cylinder on the side. One was an engine the other a
compressor[compressed air is used to start large diesels]. Made the most
perfect smoke rings when it started.
