Thomas Built Buses announces new DPF temperature stabilization
This new feature optimizes the regenerative parameters of engines, improving engine performance and enhancing the frequency of active regeneration.


Thomas Built Buses announce a revolutionary new feature for diesel engines — Diesel Particulate Filter Temperature Stabilization, also known as the “Stay Warm” feature. This new feature optimizes the regenerative parameters of engines, improving engine performance and enhancing the frequency of active regeneration.
It will be standard and factory-installed on all Cummins engines with a standard exhaust configuration starting in April 2017. More important, any customer with a Cummins engine, model year 2010 or later, can visit their local Thomas Built dealer to have their engines programmed with this new Diesel Particulate Filter Temperature Stabilization Parameter.
“Diesel is now one of the cleanest fuels available today. Yet, one of the results of diesel running so cleanly is that in some instances, engines may not regenerate frequently enough in order to properly clean out the diesel particulate filter. This lack of regeneration frequency leads to the need for more frequent service cycles,” said Caley Edgerly, president/CEO of Thomas Built Buses. “Through significant testing, we have determined that we can optimize the DPF parameters, which helps to improve the frequency of the regeneration without affecting the cleanliness of clean diesel. Through this exciting development in clean diesel, fleets will see significant improvement in their engine and DPF performance along with reduced engine maintenance, maintenance costs, and fleet downtime.”
