No Cat engine in 2010, but look for a Cat truck Caterpillar Inc. won’t be rolling out a 2010 compliant engine. Instead, look for a Cat-branded truck thanks to a new agreement with Navistar International Corp. Caterpillar and Navistar officials announced Thursday, June 12, that the companies signed an agreement to collaborate in on-highway truck and engine business. In a press release, Caterpillar officials also announced their company would not supply EPA 2010-compliant engines to truck and other on-highway original equipment manufacturers. The pair of companies will focus on global truck opportunities and more specifically on severe service construction trucks...

Looking for a fuel-efficient alternative to your current gas-guzzler? How about a car that gets 30% better fuel economy, doesn't require a giant battery in the trunk or have to be plugged into the wall, and can travel 600 miles between fill-ups? Believe it or not, automakers may have a tough time selling those attributes to consumers later this year, when a new generation of diesel-powered vehicles arrives in dealerships. Images from the 1970s--of rattling engines and tailpipes spewing black soot--are hard to shake. And, thanks to superb marketing by Toyota (nyse: TM), maker of the Prius hybrid, Americans are...

T IS just a wee bus, but it has become the new, environmentally friendly face of dirty diesel because it uses an unusual chemical - urea. Volvo's new-generation green bus is being tested on the northern beaches by Forest Coach Lines, and will one day become part of the cleaner State Transit Authority fleet. Although many argue it is not as clean as buses fuelled by compressed natural gas, it meets the emissions standard that will be required of heavy vehicles by the European Union from 2008. The bus stores the liquid AdBlue, a solution of urea - found in...

PARIS - Europe has angered the United States with talk of canceling its arms embargo against China - but governments and companies on the continent have for years delivered weapons and other equipment to Beijing and its rapidly modernizing People's Liberation Army. In Germany, a subsidiary of DaimlerChrysler AG says it is supplying diesel engines for Chinese submarines. And there's been a surge in European export licenses to China for goods - about $550 million in 2003 alone - that are designed for war or could have military and civilian applications, a gauge of Europe's growing willingness to profit from...

Smoky diesel exhaust billowing from the tailpipes of buses, trucks and construction equipment leads to more premature deaths, heart attacks and bouts of asthma in New York than in any other state, according to a report released yesterday by the Clean Air Task Force, an environmental group. The harmful effects of diesel exhaust were most severe in New York City, despite recent efforts to reduce noxious emissions. The study estimated that there were more heart attacks per capita connected to diesel exhaust in the city than in any other metropolitan area in the country. Diesel manufacturers contend that the study...
