New Diesel Technology Runs Cheaper, Cleaner
A Chinese research team has developed an affordable solution to diesel engine emissions, opening the door for expanded use of the cheaper-than-gasoline fuel.
The new engine features a catalytic filter designed to collect soot and remove oxidized nitrogen -- the two major products of diesel exhaust.
The team, comprised of researchers from the Chinese Academy of Sciences and Beijing Normal University, said the new diesel engine design is likely to meet the European III emission standards if the solution is used.
Team co-ordinator Zhuang Yahui said that a package of suggestions has been submitted advising Beijing to use the new engine, which could substantially reduce air pollution in the capital.
"Tests have shown the solution is cheap and policy makers should consider it," said Zhuang, a professor with the Research Centre for Eco-Environmental Sciences under the academy.
At present, many of the city's vehicles run on gasoline and natural gas, but some trucks still consume diesel fuel. Exhaust from diesel engines is a major contributor to air-borne particles, the main pollutants in Beijing. Cheng Ying, an official with the Beijing Municipal Environmental Protection Bureau said the new engine design could be economically and environmentally useful in achieving the Chinese capital's loft.
