Three engines are set to be developed by the company in lieu of this technology: the DD13, the DD15, and the DD16 which are still yet to be introduced into the market. The Blutech technology includes emission filtering technologies already present in today’s engines, including Diesel Paticulate Filter, Diesel Oxidation Catalyst, and Exhaust Gas Recirculation.

All three SCR (selective catalytic reduction) systems are designed to meet the EPA standards of 2010. Because these EPA standards also require the operators to fill their vehicles with DEF, Detroit Diesel is including components like the DEF tank, doser, guage, SCR catalyst and aftertreatment control module into their systems.

DEF (diesel exhaust fuel) is made up of 66.7% water and 33.3% automotive-grade urea. This fuel reacts against smog forming gases, reducing the NOx levels emitted by the vehicle. Although the Blutech technology is designed to be more environmentally conscious, it doesn’t ditch the current base engines of Detroit Diesel altogether.

The company is only working to improve their already existing base engines. Aside from the reduced NOx levels emitted by Bluetec engines, these engines are also designed to save more fuel. A significant 5% improvement in fuel efficiency has been recorded during the dry-runs of these Bluetec engines.
