As one of the biggest names in semi trucking engines in America, Detroit Diesel has led the charge in efficient engine technology for decades.

One of the ways Detroit Diesel does this is through their BlueTec emissions technology. It’s not even a major overhaul to the way the engine itself does business under the hood. The best aspects of all that power and reliability remain. So how is BlueTec so efficient?

BlueTec engine technology involves sending gases downstream, mixing small amounts of exhaust fluid into the system to combine NOx in the SCR catalyst. Fancy words aside, that means that CO2 and other emissions largely get converted into nitrogen and oxygen as they leave the truck. Both of these elements are safe for the environment in this form, which reduces the carbon footprint of every Detroit Diesel powered semi truck on the highway.

Given that most modern models of Freightliner trucks come standard equipped with Detroit Diesel, that’s a big win for the industry.

BlueTec emissions technologies are comprised of:

  • Exhaust gas recirculation (EGR)
  • Selective catalytic reduction (SCR)
  • Diesel oxidation catalyst (DOC)
  • Diesel particulate filter (DPF)

These initiatives, alongside Freightliner’s emerging hybrid semi truck technology, form an ongoing commitment to balancing unparalleled efficiency with the power it takes to get the job done. Freightliner engineers some of the biggest semi trucks on the road with the power to match, and this is in large part due to the partnership with Detroit Diesel.
