"GREEN" NEWS * USA - New diesel trucks and buses cut soot and smog more than 90%
Data show new diesel technologies are working even better than expected
Washington,DC,USA -Environmental Health News, by Marla Cone -June 18, 2009: -- For decades, diesel trucks and buses have spewed large amounts of soot, smog-causing gases and carcinogens into the air. But new diesel engines are more than 90 percent cleaner than a few years ago, far exceeding the emission reductions required by the U.S. Environmental Protection Agency, according to a new independent study released Thursday... 
Tests--conducted by independent researchers funded by a coalition of government and industry--now show the diesel technologies are working even better than expected. Truck and bus engines are much cleaner than they are required to be under new federal standards, and for many pollutants, the latest models are emitting the same levels as gasoline-powered automobiles, the researchers said...
However, one company, Navistar, has said it cannot meet the nitrogen oxides standard next year so it will use credits to offset the difference. In March, Navistar filed suit against the EPA, although the other three companies have filed a brief in court supporting the EPA rule... Other diesels, such as construction and farm equipment, must meet the same emission standards, but have until 2013, or in some cases, 2015, to do so. The new tests only checked truck and bus engines... To meet health standards at many U.S. cities with heavy particulate pollution, manufacturers of both gasoline and diesel engines may have to face even tougher emission standards in the future, Daniel Greenbaum, president of the Health Effects Institute, said...* Maxwell, ISE To Cooperate on Hybrid Systems for Buses and Trucks
San Diego,CAL,USA -Sustainable Business/Reuters -Jun 18, 2009: -- Maxwell Technologies, a manufacturer of energy storage products, and ISE Corporation (ISE), a designer and manufacturer of hybrid propulsion systems and components for heavy-duty vehicles, have signed a Memorandum of Understanding (MOU) outlining the formation of a strategic alliance to develop and market high-voltage energy storage systems for fuel-efficient, low-emission, hybrid-electric buses and trucks... Under the agreement, ISE will source ultracapacitor cells exclusively from Maxwell; and Maxwell will source and market through certain high-voltage and high performance ultracapacitor modules designed and produced by ISE... The agreement builds on a relationship that began in 2002, when Maxwell began supplying its BOOSTCAP ultracapacitors to ISE for braking energy recapture and torque assist in ISE's hybrid drive systems for heavy-duty vehicles..
