More fuel efficient-idling vs switching off when stopped?

[ISUZUROVER]

.....
And from what I have seen every governed diesel engine when shut down (Fuel rack will go to the no fuel position) will reset to full fuel in rest position, so when it starts up it is at full fuel, even if for just a very short time.

its been a long time since i looked at it but not from what i can remember.
shut off at idle, control arms almost at minimum, governor will retract when its stopped so it will move the control arm a little bit toward more fuel.
but to go full fuel it would have to fight against the control spring. control spring tries to keep it at idle because thats where the throttle is.

My inline pump has a control cable which locks it into full fuel for startup. This remains until the governor senses enough speed to unlock it and return to governor control.

Any estimates on how long this takes?

I think somewhere between idle and cranking speed it releases.

So on a di engine like a 4BD1 you would be at max fuel for 1-2 revolutions of the engine and maybe another 10 revolutions until cranking speed had been reached???

Any specs on the fuel delivery at max fuel vs idle?

Bush65 has all the specs on delivery volumes. I remember seeing 220 cc/thousand shots but can't recall if this was a 4B or 4H series Isuzu.

Doing a good job to change the stereotype about people from Gympie...

What f@#$%&ing c#%% ar$#@@%le stereotyped us people from Gympie anyway, and what stereotype is that

Come on give us a break, we've only got 2 traffic lights in town so I'm not used to sitting a the lights for more than 20 seconds per day. This new environmental practice will surely blow that time out to easy 30 seconds, let alone when I go to the Big Town once a year for the gun lovers association AGM

What about the oil draining from the engine? Would the wear and tear from starting a "dry" engine be significant?

I notice truckies often leave their trucks idling while they stop at roadhouses etc.
