This was vaguely discussed some time back but I don't remember any conclusive information and did not find anything while searching.

Does anybody know for sure whether or not the FZJ 80 shuts down its fuel injection system while coasting to conserve fuel?
In principle that would be a good idea, of course, assuming the engine would not run rough and there would be no issue reigniting things up when needed.
IIRC, I worked on a euro Diesel a long long time ago that did that. I imagine it's probably not unheard of if not downright common in at least Diesel engines and probably some gas engines (no idea).

Anybody knows for sure?
