Can clean diesel power past gasoline?
To those worried about air pollution, America’s enginemakers want to say two words: Clean diesel. Admittedly, it sounds like a contradiction. Nevertheless, urged on by ever-tougher emissions standards, manufacturers and researchers are turning sooty old truck engines into clean-burning power plants. By Laurent Belsie | Staff writer of The Christian Science Monitor If they meet the challenge, the nation’s trucks, buses even many of its sport-utility vehicles and cars will be running on clean diesel for years to come. The technology may raise the costs of driving. It will almost certainly boost the nation’s freight bill. Still, it would push onto America’s highways vehicles that get higher mileage and pollute less than today’s cars and trucks. “Not very many experts in this field have much faith in the future of gasoline engines,” says Stephen Ciatti, a clean-diesel researcher at Argonne National Laboratory in Argonne, Ill. “Either diesel engines or fuel cells will be the likely contende
