Cummins white paper on secrets to better fuel economy

[ohnoitsyu]

I apologize if this is old info (it is old, based on the cost of diesel quoted in the paper), but I haven't seen this before, and others may not have either. It's obviously directed at big rigs, but there is a lot of useful information for us.

Interesting information.

Thanks ,

Something about that I found interesting. While it's commonly known that as a diesel engine breaks in it will get better mileage, it's mentioned in the white paper that worn tires will also improve the mileage (no surprise). This means that the gains experienced at 10k, 20k, 30k, and so on aren't only contributed to the engine breaking in, but the tires wearing out.

Thanks for that! Very interesting.



"At approximately 0. 3 lb. /BhpHr fuel consumption, a reduction of 35 Bhp required to cruise at 65 mph results in a savings of about 10. 5 lbs. of fuel every hour (0. 3 x 35 = 10. 5). Since diesel fuel weighs about 7. 1 lb. /gal. , this amounts to a savings of 1. 5 gallons of fuel saved every hour (10. 5/7. 1 = 1. 5). For a truck running 10 hours per day, that’s 15 gallons of fuel saved per day. At $1. 50 per gallon of fuel, the dollar savings is $22. 50 per truck per day. "



So I guess $3. 00 per gallon of fuel it's going to be $45. 00 per truck per day saved now.
