AirFlow BulletTruck achieves 13.4 Average Miles Per Gallon
during a coast-to-coast, real-world,
revenue producing freight run!
We just finished up a coast-to-coast, revenue-producing, real-world, freight hauling run.
Nevermind that test-track stuff. Welcome to the real world.
We loaded in Connecticut and our first stop was in Tracy, California. We ran into 35 mph 3/4 headwinds all the way through Wyoming and 40 mph crosswinds traveling through Utah.
But we still achieved an amazing 13.4 mpg average for the entire coast-to-coast trip.
Here are a couple of pics of the BulletTruck high-definition engine display. The first one is just like it says, a leg from Gary, Indiana to Cheyenne, Wyoming. As you can see in the center top box, we are traveling 55 mph.
Upper left corner is the time at 3:04 in the afternoon.
We are doing 14.2 instant mpg at 17% engine load which means we are climbing uphill. Level and straight with no grade we would be 10% engine load and 17.5-18 mpg. But that Instant MPG does not really mean a thing as far as documenting mpg. It is just feedback for my driving. We can make it display anywhere from 3 mpg to 256 mpg depending if I am going up or downhill.
The three numbers in the lower right corners are the key. This is what shows the average mpg for that leg of the trip. They show 950.5 miles traveled since we reset the readout in Gary, Indiana after buying 100 gallons of fuel. We burned 67.4 gallons which shows as an 14.1 mpg average fuel burn. We also averaged 14.1 from Connecticut to Gary, Indiana. I know how to spell Cheyenne when I'm not so sleepy.
The second pic is right after we got unloaded in Tracy, California. As you can see, we traveled 3043.0 miles coast-to-coast. The lower right 2117.9 is the distance from Gary to Tracy. Have you ever noticed how many towns are named after humans??? So for that 2117.9 miles we consumed 157.8 gallons of fuel for 13.4 mpg average.
We apologize for the poor quality of this pic. The white spots on the bottom are dust reflections either on the camera lens or dust on the face of the display.
We stopped by to see the nice folks at the Cummins Technical Center in Columbus, Indiana after unloading a shipment of freight nearby. In this photo, some of the Cummins engineers are getting their first in-person look at the AirFlow rig. We have been working long-distance with the engineers at Cummins for years on the BulletTruck via e-mail and telephone calls. They helped us redesign the belt drive system and the cooling system of the ISX. And Cummins has been one of our original Partners since way back in 1983, when we built the first AirFlow rig.
One of the engineers from the Vehicle Integration - Electronics group is shown downloading data from the AirFlow rigs ECM into his laptop. ECM stands for Electronic Control Module, which is the engine computer and the brains of the Cummins ISX engine. The ECM receives data from a multitude of sensors throughout the vehicle, and operates the engine according to this data within design parameters.
We felt honored and privileged to be working inside the Tech Center with all of the Cummins engineers. The access door on this bay had a sign that read:
With so many students enrolled, they came outside in waves to check out the AirFlow rig so they would not overwhelm us and the facility. The groups were based upon their primary area of study, Automotive, Diesel, Body Work, etc.
They asked great questions and we answered them and explained the technology and the fabrication involved in a project such as this.
We also explained how "saving fuel is the new going fast."
Here is the new AirFlow BulletTruck parked at AirFlow Truck Company World Headquarters in Connecticut.
After the show at MATS, we just completed a 3500 mile shake-down test. A real-world freight hauling run, ranging from freezing temps in the north, to high 90'sF in lower Texas a mile from the Mexican border.
Coolant temps averaged 185F and underhood temps averaged 110F.
We hauled paper products, Sony electronics, and plastic paint can covers (304,200 of them, to be exact) on real revenue-producing freight runs.
Even though we were showcased at the world's biggest truck show at MATS, this is a not a show truck.
