Emissions testing for Mazda's new diesel engine faces difficulty

Mazda began talking up its plans to launch a new diesel engine to the United States a while back. Mazda wanted to put the diesel engine under the hood of its new Mazda6 in the U.S. during the second half of 2013.
 
However, it appears Mazda is having a hard time getting the engine certified for use in the United States. Due to delays in certification, the engine has been pushed until late spring of 2014. The company says that it's currently still working on emissions testing for the U.S. market.

Mazda said, "The on-sale date for Mazda6 Skyactiv-D clean-diesel has been moved to late-spring 2014, to accommodate final emissions testing and certification....More information on the Skyactiv-D clean diesel Mazda6 will be available closer to the on-sale date."

Robert Davis, senior vice president of U.S. operations for Mazda said, "I know we had discussed it being in showrooms before the end of the year, and everyone involved in the program is disappointed it will not be, but final certification testing -- the results of which are looking encouraging -- is taking longer than we had initially expected."

Mazda had also hoped the new diesel engine would help further increase its sales in the U.S.  Mazda6 sales were up 167% in August compared to August of 2012, but are starting to slow.

If diesels are so clean why is Mazda having trouble meeting emissions standards?

Diesel cars pollute more, its just a fact. Lets just chill with the rhetoric and move on.

Not that I personally care about vehicle pollution mind you.

Dunno dude...

quote:
Photo of a meadow, trees and mountain range Major benefits from Ultra Low Sulfur Diesel fuel with diesel engine and vehicle advances. ULSD fuel enables the use of cleaner technology diesel engines and vehicles, resulting in significantly improved air quality. Annual emission reductions will be equivalent to removing the pollution from more than 90 percent of today’s trucks and buses, when the current heavy-duty vehicle fleet has been completely replaced in 2030. Tests completed by EPA, the California Air Resources Board, engine manufacturers and others show that using the advanced emissions control devices enabled by the use of ULSD fuel reduces emissions of hydrocarbons and oxides of nitrogen (precursors of ozone), as well as particulate matter to near-zero levels. EPA studies conclude that ozone and particulate matter cause a range of health problems, including those related to breathing, with children and the elderly among those most at risk. EPA estimates that there are significant health benefits associated with this program. As an additional environmental benefit, ULSD fuel enables diesel-powered passenger cars and light trucks to meet the same stringent emissions standards as gasoline vehicles. Diesel-powered vehicles tend to be more fuel efficient than gasoline-powered vehicles. For more information on health and environmental benefits, visit www.epa.gov/cleandiesel.

Particulate is one of the issues. Another is nitrous oxide, the thing that causes companies to often use urea systems in addition to DPFs (particulate filters).
