TMC adds new recommended practice on leak detection in engine systems

The American Trucking Association’s Technology and Maintenance Council (TMC) added a new Recommended Practice (RP) titled RP 375 Leak Detection in Engine Systems Utilizing Visible Vapor Technology. After much research, testing, and consultation in the industry, the new RP was developed to help resolve the costly concern of engine air leaks.

The announcement was made by Alex Parker, CMO and executive vice president of Redline Detection, during a press conference. Redline Detection has been working in conjunction with TMC for the past three years as an industry expert in leak detection.

“[Aftertreatment systems] have been very problematic and turned into one of the top costs for heavy duty and fleet operators,” Parker said. “Everyone is really looking for ways to streamline these aftertreatment problems and excessive aftertreatment maintenance.”

During their research, TMC found that upstream component leaks, faults, and unmetered air leaks in the engine system will cause a vehicle to take in more fuel, alter the air fuel ratio, cause DPF filters and aftertreatment systems to clog prematurely, and cause a vehicle to derate. These air leaks resulted in increased maintenance and vehicle downtime.

Fleets who have implemented the process of using high pressure leak detection technology not just for repair of known problems, but also as preventive maintenance have seen a demonstrable ROI, as well as an increase in uptime, lower maintenance costs, and increased mpg, Parker stated.

“We're really excited about this announcement,” Parker said. “It's been a lot of work in the process, and it's really going to be a game changer for the heavy duty industry.”
