This study focuses on optimizing the selective catalytic reduction (SCR) system to reduce urea deposits and enhance overall system performance. Both computational fluid dynamics (CFD) simulations and ...

Pollutants emitted from combustion sources have been regulated by local and federal governments since the early 1960s. Specific rules vary by state and air district, but they generally apply to ...

Selective catalytic reduction (SCR) systems employing a urea-water solution inject a measured dose of aqueous urea into exhaust gases, where thermal decomposition and hydrolysis generate ammonia. This ...

Emission regulations for combustion systems have been in place for more than half a century and in the 1990’s, the Clean Air Act put a spotlight on emissions specifically from industrial boilers.

PACCAR has been granted a patent for a method involving a heavy-duty truck’s diesel engine and exhaust after-treatment system. The system includes selective catalytic reduction systems and NOx sensors ...

The Engine Technology Forum (ETF) today announced the launch of its new Selective Catalytic Reduction (SCR) & Diesel Exhaust Fluid (DEF) Policy ...
