The Dept. of Energy (DOE) recently recognized Power Service Products (PSP) for its fuel additive that significantly decreases NOx emissions while improving fuel economy.

In a DOE-backed pilot program, PSP’s Diesel Kleen additive was found to reduce fuel consumption 4% while cutting NOx emissions 9% to 28% for transit buses running biodiesel, said PSP.

In conventional diesel blends, Diesel Kleen would provide similar improvements in NOx emissions and fuel economy, David Doremus, PSP spokesman told Fleet Owner.

PSP was involved in a project with Nashville’s Metropolitan Transit Authority to reduce emissions and fuel consumption. PSP is a stakeholder in the Clean Cities of Middle Tennessee Coalition, a participant in DOE’s Clean Cities program.

“Power Service makes a wide range of additives that can dramatically reduce diesel fuel emissions and improve fuel economy,” said Ed Kramer, president of PSP. “For this to be formally recognized by a federal program charged with reducing fuel consumption is a great honor for our company.”
