GREEN BAY, Wis. — Schneider National has received the first two Detroit Diesel customer demonstration units (CDUs) with selective catalytic reduction (SCR) and has been putting them through the paces since January, the companies have announced.

The engines feature Detroit Diesel’s SCR technology which is dubbed BlueTec. Schneider has integrated the two engines into its fleet to collect real-world data and has been sharing that information with Detroit Diesel on a daily basis.

So far, the engines have racked up more than 45,000 miles.

“By actually field testing the technology, we are putting the units into real-life situations, which ultimately helps Detroit Diesel engineers to identify every possible issue in advance,” said Steve Duley, vice-president of purchasing for Schneider National. “We are confident the experience we gain from CDUs will give us additional time to prepare for the transition.” 

More than 90% of Schneider’s fleet is powered by Detroit Diesel engines, according to the company.

“Wise use of our natural resources is important to our customers and to Schneider National,” said Duley. “New technologies and spec’ing our equipment with energy-efficiency in mind is critical to delivering on that promise.”
