STEMCO introduces efficiency test for aerodynamic equipment

STEMCO dataloggerSTEMCO has developed a new fuel efficiency testing technology for its TrailerTail aerodynamic equipment.

The real world DataLogger test provides fleets with an extremely fast, precise and significantly less expensive method of testing the fuel efficiency of TrailerTail technology using a fleet’s own truck, trailer and driver in under four hours, STEMCO says.

The palm-sized DataLogger (developed in partnership with IOSiX, LLC) plugs directly into the tractor’s J1939 diagnostic port and accesses engine data. A STEMCO field technician conducts a controlled test with the fleet’s truck, trailer and driver. STEMCO engineers then analyze the data to precisely break down how much fuel the TrailerTail system will save that specific fleet, the company says.

“TrailerTail technology has proven in numerous standardized aerodynamic tests that it reduces fuel consumption by over five percent at highway speeds,” says Bob Montgomery, vice president of the Innovative Tire & Mileage Solutions group at STEMCO. “But many fleets really want to know that it will work for them in their specific operation, not just on a test track or in someone else’s fleet. The DataLogger provides a means to prove fuel savings in a matter of hours.”

STEMCO says the technology’s testing protocol and filtering algorithm were developed specifically to provide a customized data stream that isolates the aerodynamic variables while minimizing the disruptive effect that inconsistent wind, temperature and traffic can have when comparing different test runs to measure fuel economy improvements.

More than a dozen fleets have tested TrailerTail using the DataLogger with results consistently approximating 4.5 percent, equating to an average mile per gallon improvement of 0.44. These results are also consistent with fuel savings reported from fleet-wide TrailerTail deployments.
