Re: 2 stroke
There was an article a couple of years or so ago in a maritime trade magazine (I saw the article in a lounge at a tugboat company I used to work at) about a catamaran ferry in the San Francisco Bay that they tested biodiesel in. The boat was powered by two 12V-71 Detroit 2 strokes, and there weren't any issues. I seem to recall the fuel consumption being slightly worse, but the boat ran cleaner and I believe that, on the post-test inspection teardown, the insides of the engines were cleaner than they were on the pre-test inspection teardown.
I would imagine that there have been more recent testing, but I haven't seen anything...I'm sure someone else has, though. [img]/ubbthreads/images/graemlins/smile.gif[/img]
