correct idling r.p.m.

[heavyhaulerss]

what is the correct r.p.m.'s for a 11.1 detroit motor to idlle, when running truck overnight? is there different r.p.m's for different temps?

We usually set ours to run at 1000-1100 if idling for extended periods. This works well to help A/C in the Summer and also with heat in the winter. This also prevents loading a cylinder with fuel eliminating cold smoke when you gas on it. We set 12.7's and 14's the same way.

idling at base engine idle speed (6-750rpms) will cause cylinder liner glazing... then blow-by, the pistons have to be pulled to correct this condition

diesel engines should not fall below 165 deg f during long idle periods

pay attention to anti-idling laws. there is a free guide on;

I boost my idle up just enough to stop the loud rattles in my old Freightshaker - about 800 RPM does it. Can't sleep at the normal idle of 600 RPM .

That's true-I idled mine around 8-900
