Odd title, right?
Anyway, I got to thinking about the way diesels are governed and how that might be an issue at idle, IF there is a driveline (or grounding) problem.
I have heard stories, that I cannot authenticate, of trawler diesels spinning off their mounts due to a line fouling the shaft.
So, perhaps my question is this. How much fuel flow is fed when a diesel is jammed up at idle (not allowed to reach idle rpm)? And, is this different with electronic vs mechanical injection?
One of the benefits of diesels are the wide range of fuel to air mixes that still allow combustion, and the constant rpm nature of the governers when in seas, towing, etc.
