Brendan Foster, president of DEF pump distributor, Benecor, agrees. “I believe DEF will be easily available, but more common as a packaged product initially. Due to the economic conditions that the country is facing, the market has taken a definitely more conservative approach to how they roll out larger quantities.”

The 2010 lineup — Engine makers say they are ready

Cummins | www.everytime.cummins.com

The engine maker changed course and announced in August 2008 that it would use selective catalytic reduction (SCR) with heavy-duty engines. It says the U.S. Environmental Protection Agency has no concerns regarding the use of its copper zeolite-based catalyst, which the engine maker says provides a much higher NOx conversion efficiency than iron zeolite catalysts. Cummins also says it is on track to exceed its field test mileage target for both its heavy-duty and midrange engine lines. At production launch in January 2010, Cummins heavy-duty field testing will top 3 million miles, and midrange field testing will approach 2 million miles. The company reports positive feedback on performance and fuel economy from field test customers.

Detroit Diesel | www.detroitdiesel.com/emissions/epa2010

Detroit Diesel says it designed the DD13, DD15 and DD16 engines with 2010 emissions regulations and SCR aftertreatment in mind, so the engines themselves will see virtually no changes from the current design. The company says its 1-Box BlueTec SCR design integrating the diesel particulate filter (DPF) offers compact packaging and enhanced exhaust flow.

Mack Trucks | www.mackscr.com

Mack says its engines do not change for 2010. The company introduced the first member of its Mack MP engine series – the 11-liter MP7 – in late 2005 in an EPA ’04 configuration. Now, for EPA ’07, Mack offers the MP7, MP8 (13-liter) and recently-introduced MP10 (16-liter). All were designed from the beginning with the EPA’10 regulations in mind.

Navistar |Maxxforce.com

Navistar says no changes will be made to its exhaust gas recirculation (EGR) MaxxForce 11 and 13 big bore engines for 2010, and there will not be an SCR aftertreatment system. Navistar says its 2010 engine models have been in commercial service since January 2007 and have logged hundreds of millions of real-world miles. Navistar plans to introduce a 15-liter MaxxForce 15 in early 2011 and will bridge the gap with a combination of 2009 engines carried over into 2010 and a transitional 15-liter engine that it isn’t yet discussing publicly. Navistar also believes that many customers will choose to move from 15-liter to 13-liter engines due to weight and fuel economy.

Paccar | www.paccar.com/engines

The parent company for both Kenworth and Peterbilt trucks has not released the exact number of test trucks in its test program, nor the miles that program has accumulated to date. A company spokesman says Paccar is actively testing the 2010 engines – through field tests with customers, with trucks running on its test tracks and road tests conducted by company personnel, and in test labs to identify issues and validate components and installations – and notes the company is planning for engine availability in January 2010.

Volvo | www.volvoscr.com

There will be no changes to Volvo’s family of diesel engines in 2010 beyond the addition of SCR aftertreatment systems to meet EPA ’10 emissions requirements. Volvo has more than 150,000 SCR trucks on the road in Europe and has logged more than 2 million test miles on its 2010 engines in the United States alone. The manufacturer also emphasizes that its 2010 solution will eliminate active regeneration of DPFs during normal highway operations.
