PORTLAND, OR - Daimler Trucks North America announced pricing for meeting EPA2010 standards with its Detroit Diesel BlueTec or Cummins mid-range engine emissions technologies.

  • A surchange of $9,000 per vehicle will be added for vehicles equipped with Detroit Diesel DD15 and DD16 big bore engines, as well as the medium bore DD13.
  • A surcharge of $7,300 will be added to vehicles equipped with the Cummins ISC8.3 engine.
  • A $6,700 surcharge will be added to the price of vehicles equipped with Cummins ISB6.7 engines.

The surcharges reflect costs associated with adding selective catalytic reduction (SCR) which has been proven to significantly improve fuel economy compared to EPA 2007 engines while reducing long-term operating costs and meeting the stringent, near-zero emission standards set by the U.S. Environmental Protection Agency (EPA) that take effect January 1, 2010.

SCR is an emissions technology that treats NOx emissions downstream in the exhaust so that the engine can be tuned to run more efficiently and economically. SCR technology consists of an after-treatment catalyst system that allows engine exhaust to be treated with a non-hazardous fluid known as diesel exhaust fluid (DEF) that reduces harmful NOx into simple nitrogen and water.

Advanced electronic engine controls link the elements of the system to make SCR a convenient and economical solution for vehicle owners and drivers. And since virtually no base engine changes are needed for SCR to work, service technicians will also find no engine maintenance changes for EPA2010.

Detroit Diesel BlueTec fuel efficiencies are the result of three optimization factors which are: base engine-out NOx levels, diesel particulate filter (DPF) regeneration intervals, and exhaust back pressure. In addition, reduced reliance on exhaust gas recirculation (EGR) lowers heat rejection which means no expansion of cooling capacity and no resulting impact on aerodynamics or under-hood packaging.
