WEST LAFAYETTE, Ind. – Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution-control systems to further reduce emissions of smog-causing ...

Since 2010, diesel-powered on-highway trucks in North America have been using selective catalytic reduction (SCR) as an exhaust after-treatment technique to control nitrogen-oxide (NOx) emissions. And ...

Diesel engines are something of a mystery to many drivers, especially in North America where gasoline is the king of motoring fuels. Of course compression-ignition has a host of benefits compared to ...

Adding diesel exhaust fluid to trucks has become fairly routine, despite some of the anxiety that came along with the debut of this new fluid a decade ago, needed to cut emissions using selective ...

The EPA is escalating its response to consumer complaints regarding DEF system failures, announcing a new investigation aimed at 14 major manufacturers.

The first Diesel engines were started 130 years ago, but they have moved a long way since then. Like their gasoline counterparts, the compression ignited engines have evolved from the rough units of ...

Increasingly stringent diesel engine exhaust emissions regulations have, over the past 20 years, reduced output of nitrogen oxides (NOx) by 95% and particulate emissions by 90% in heavy trucks. These ...

Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution-control systems to further reduce emissions of smog-causing nitrogen oxides in diesel ...
