Researchers from Purdue University and Cummins Inc. have developed an advanced "closed-loop control" approach for preventing diesel engines from emitting greater amounts of smog-causing nitrogen oxides when running on biodiesel fuels. Operating truck engines on a blend of biodiesel and ordinary diesel fuel dramatically reduces the emission of particulate matter, or soot. However, the most modern and efficient diesel engines burning biodiesel emit up to 40 percent more nitrogen oxides at some...

BETHESDA, Md., Jan. 21 /PRNewswire-USNewswire/ -- Your car's exhaust system has come a long way from the old days of exhaust pipes and mufflers. Today, the exhaust system is safety and emissions control rolled into one. Your vehicle's exhaust system consists of one or more mufflers, one or more oxygen (O2) sensors, one or more catalytic converters, a tail pipe and an exhaust pipe. The exhaust system routes dangerous exhaust gas from the engine out and away from the car to keep from...

A McMaster University researcher has found the first evidence that prolonged exposure to higher levels of the pollutants found in car exhaust fumes and industrial air pollution can lead to hospitalization for pneumonia in adults aged 65 and older. Infectious disease specialist Mark Loeb led a research team to assess the effect of long-term exposure to nitrogen dioxide and sulfur dioxide, both found in motor vehicle emissions, and fine particulate matter, found in industrial air pollution, on...

Diesel's alma mater drives engine technology toward green extreme Just three months after the Euro 5 Norm for exhaust emissions went into force for all new car models, researchers at the Technische Universitaet Muenchen (TUM) have demonstrated an engine that is already close to meeting the more stringent Euro 6 emissions standard. A research team headed by Prof. Georg Wachtmeister from the Chair of Internal Combustion Engines has succeeded in reducing the pollutants in exhaust emissions to...

Tree leaves may be powerful tools for monitoring air quality and planning biking routes and walking paths, suggests a new study by scientists at Western Washington University in Bellingham. The research will be presented at this month's Annual Meeting of the Geological Society of America in Portland, Oregon. Leaves along bus routes were up to 10 times more magnetic than leaves on quieter streets, the study found. That magnetism comes from tiny particles of pollution"”such as iron oxides...

The air people breathe while walking in the park, working in the garden or shopping downtown may be unhealthy enough to seriously spike their blood pressure, a new study suggests. Cardiovascular researchers at the Ohio State University Medical Center are the first to report a direct link between air pollution and its impact on high blood pressure, or hypertension. If the results from these animal studies hold up, this could be important for human health. "We now have even more compelling...
