Catalytic converters are quite common for gasoline engines but diesel catalysts are less known, in part because they face greater challenges. Still, diesel catalysts have not disappeared because they are efficient and, when you start your car, they don't produce heaps of CO2. Their main problem is ...

Could urea be a savior when it comes to reducing atmospheric carbon dioxide? By now we all know about injecting urea into diesel engine exhaust to reduce emissions of nitrogen oxides. An Australian company has now received permission from the government of the Philippines to dump urea into the Sulu ...

Before the low sulfur diesel fuel that has become common here in the United States, it was impossible for automakers to install filters which would allow diesel engines to meet the requirements which were being imposed upon them. Fortunately, everything is coming together here in the States to ...

While DaimlerChrysler announced at the start of this year it would be introducing its E320 BLUETEC with clean diesel technology as a 50-state vehicle, the car will be hitting showrooms as a 45-state compliant car. BLUETEC, DaimlerChrysler's aftertreatment system promises to meet the upcoming EPA ...

Following up on Derrick's post from yesterday, one other option the Environmental Protection Agency (EPA) may use is to require the urea refill interval to be at least as long as the manufacturer's oil change interval, allowing the urea refill to coincide with oil changes.If you missed yesterday's ...

By 2010, all diesels sold in the U.S. will have to meet Tier 2 Bin 5 emissions levels, the same standards as their gas-powered counterparts. Even though we're used to talking about diesels as green machines, they still have the issue of nitrous oxide (NOx) emissions with which they need to ...

Reports from the British International Motor Show, which starts tomorrow, revealed BMW plans to have diesel-powered cars available in the U.S. by 2008. The company plans to use a urea-based additive system to meet the strict U.S emissions standards. The system will make the cars available in all 50 ...

Ford Motor Company's Volvo unit wants to launch a diesel car in the U.S. by the end of the decade. The challenge is meeting the stringent emissions standards, which are focused more on regulating oxides of nitrogen in North America. The European Euro 5 standards, the upcoming standard for European ...
