Multiparty study finds effort exceeded expectations

---

A study shows that clean diesel technologies in engines manufactured beginning in 2007 not only reduced certain emissions by 90 percent over 2004 models, but also far exceeded expectations in their performance in cleaning up the nation’s air quality. The study – sponsored by a multiparty group of government and industry organizations, including the U.S. Environmental Protection Agency, the U.S. Department of Energy, the California Air Resources Board and the Engine Manufacturers Association – is the first phase of the Advanced Collaborative Emissions Study (ACES). This five-year comprehensive emissions testing program will test the emissions and health effects of new-technology diesel engines to document the improvements that have been made and to ensure that there are no unintended emissions from these new technologies.

Emissions reductions by 2007 model engines “exceeded substantially even those levels required by law,” said the study, conducted by the Coordinating Research Council and the Health Effects Institute. Current engine models produced 98 percent less carbon monoxide, 10 percent less nitrogen oxide, 95 percent less nonmethane hydrocarbons and 89 percent less particulate matter than required by EPA’s diesel engine emissions standards, the study found.

“Diesel engines are the workhorses of the nation’s transportation infrastructure because they are fuel-efficient, durable and reliable,” says Jed Mandel, president of the Engine Manufacturers Association. “We can now add near-zero emissions to the list of diesel’s positive attributes.”

Double Coin rolls out new tires
Chinese tire manufacturer Double Coin and its North American marketing branch CMA recently discussed several aspects of its current business plan and debuted a wide range of new truck tires at its distribution center in Memphis, Tenn.

The Shanghai-based tire manufacturer has been doing business in North American since 1992, primarily as a Tier 3 product supplier. But according to CMA President Mike Yang and Vice President Aaron Murphy, the company gradually will expand its product lines into Tier 2 and Tier 1 market segments in the future. The key, according to Murphy, is to offer quality tires at Tier 3 prices, gradually gaining the reputation and product awareness that eventually will allow Double Coin to compete with established Tier 1 tire suppliers.
