Fuel Consumption Testing at DPC 2016
A revamped fuel-consumption test was introduced at Diesel Power Challenge 2016. The new method of evaluating diesel usage, far removed from the 100-mile drives and locking gas caps (ugh) of the past, is the brainchild of Editor KJ Jones and ATS Diesel Performance’s race shop technicians Devin Dahlin and Mark Sanders, who learned during the development of this segment that a driver’s ability (or inability) to concentrate has a big effect on how well or poorly he or she finishes.
The new test takes place on the dyno at ATS Diesel Performance, and it basically pits competitors against one another and the computer as they operate their rigs at varying speeds (as low as idle to a top speed of approximately 60 mph) through a driving simulation that’s based on the emissions tests conducted by the California Air Resources Board.
The test involves topping off fuel before a run (using a metered pump for accurately measuring the amount of fuel delivered into the tank) and then adding fuel again until the tank is full, recording the amount that was consumed during the “road trip” (with a one-tenth of a gallon penalty assessed for each instance that a driver does not maintain compliance with the simulation). The important thing to note about this new test is that it is 100 percent self-contained in the ATS dyno cell (no smoking DPC trucks driving on public roads), and it also provides an impression of how “driveable” a high-powered diesel pickup really is.
