Simple, Cost-effective, Ready
It's Simple
Because of the many benefits SCR technology offers purchasers, drivers and technicians, SCR is the clear choice for meeting EPA 2010 emission standards.
- Engine changes are minimized and efficiency is maximized because SCR is an aftertreatment technology.
- Maintains all the options you expect, from A/C condensers and roomy luggage compartments to wheelchair lifts
- Maintains daily ease of use. Requires only a glance at the dash-mounted diesel exhaust fluid (DEF) gauge.
- Eliminates driver fill ups. DEF tank fill intervals allow for fill at regular technician servicing.
It's Cost-effective
With a reliable and proven engine architecture, SCR is the only clean-air technology that actually pays you back over the life of your bus.
Cummins Inc. conducted testing of both SCR and In-cylinder EGR systems and determined that SCR technology is better for customers because of the following:
- In-cylinder EGR reduces engine life by 20-25%
- SCR has greater component reliability
- SCR technology can achieve a 7-27% fuel economy advantage over In-cylinder EGR
A 7% fuel economy advantage saves more than $600 per bus per year, even after factoring in the cost of DEF.
It's Ready
Thomas Built's SCR emission technology is ready.
SCR is the mainstream technology that manufacturers of 90 percent of North American on-highway engines will use to meet 2010 emission standards: Daimler Trucks, Cummins and Detroit Diesel. And in the consumer car industry, BlueTec is becoming the SCR technology of choice. Currently, SCR systems can be found in Mercedes-Benz, Audi, BMW, Jeep, Kia, Mini, Volkswagen and Hyundai.
The technology backed by millions of miles. Daimler Trucks alone logged more than 30 million SCR testing miles in North America and 2,500,000 customer test miles. More than 600,000 SCR vehicles operate in Europe, from Scandinavia to the Mediterranean, and more than 245,000 of them are Daimler and/or Cummins SCR vehicles.
