Question 19

Q.		Do the major engine manufacturers publish any idling estimates to help determine the amount of fuel consumed while idling? If so, how do I get a copy of these.

Yes, they do. You can find that information from the specifications of the engines. You should be able to find this info on the web. Some research is involved. General Rule of thumb is 1/2-3/4 gallon of fuel at idle running at 650-750 rpm.
Also; every 10% decrease in idle time equates to approx. a 0.1 increase in mpg.
Cummins has a great paper called "Secrets of Better Fuel Economy" you can find that at
