Report: Roads laced with titanium dioxide could help us breathe easier

Researchers at the Eindhoven University of Technology (EUT) may be on the brink of discovering a breakthrough that will lead to reduced pollution and cleaner air for all. According to the EUT, a roadway made of concrete blended with titanium dioxide can effectively remove up to 45 percent of the nitrogen oxides that it comes in contact with. The titanium dioxide, a photocatalytic material, captures airborne nitrogen oxides and, with the aid of the sun, converts it to nitrates that are harmlessly

New Accord diesel to hit 52 MPG?

British motoring mag Autocar is reporting that the new Accord diesel we recently told you about will get really good mileage. That might seem like a no-brainer, but w

Removing nitrogen-oxide emissions from diesel exhausts without urea

Whether or not you believe in global warming, nitrogen-oxides, or NOx, definitely does contribute to acid rain and smog, which are not debatable. Because NOx is emitted in large quantities from the exhaust of diesel engines, something needs to stop it from entering our atmosphere. One way to do this is with Jeremy Korzeniewski

New ACE diesel engine claims to cut nitrogen oxide emissions 80%

New ACE Institute in Japan claims to have devised some new technology for diesels that they are claiming reduces nitrogen oxide emissions by up to eighty percent when the engines are fueled on canola-based biodiesel. They are using a mix of exhaust gas recirculation and high turbocharger boost to triple the combustion pressure. New Ace has been testing different combinations of EGR, boost, injection pressures and variable valve timing stra

Clearer skies through NOx legislation, smog levels down in East

In an annual report, the Environmental Protection Agency stated that smog levels have dramatically dropped for 19 Eastern states covering roughly 1/3 of the nation's population. The reduction is primarily due to fewer emissions of nitrogen oxides (NOx) from industrial plants and manufacturing facilities. According to the report, NOx emissions went from 1.2 million tons in 2000 to 530,000 tons in 2005. Other major sources of NOx are vehicle exha

Consumer Reports tests 2007 Tahoe on gasoline and E85

Consumer Reports discovered the overall fuel mileage on a flex-fuel 2007 Tahoe went from 14 mpg on gasoline to 10 mpg on E85.
