There are two alternative, main technologies for removal of nitrogen oxides (NOx) from
vehicle exhaust gases, namely, selective catalytic reduction (SCR) and NOx storage and …

To treat the NOx emissions from diesel vehicles, NOx selective catalytic reduction (SCR)
process by NH3 requires the use of a precursor: an urea aqueous solution. Using an …

Over the past few decades, nitrogen oxides (NOx) from mobile and stationary sources have
become a major environmental concern. Environmental regulations about NOx reduction …

The selective catalytic reduction (SCR) of nitrogen oxide (NOx) with ammonia (NH3) or urea
((NH2) 2CO) as a reductant is becoming a promising method for near future diesel exhaust …

Diesel vehicles have significant advantages over their gasoline counterparts including a
more efficient engine, higher fuel economy, and lower emissions of HC, CO, and CO₂ …

Strategies to achieve RDE requirement for diesel passenger car are introduced in this paper
focusing on NO x storage and reduction (NSR) technologies. High NO x conversion …

Automotive catalyst technology is now faced with very difficult problems. As a result of
automakers' efforts to produce more efficient and lower-emission vehicles, lean-burn …

The NOx storage reduction (NSR) process is commonly envisaged for the NOx treatment of
exhaust gas from lean-burn engine vehicles. NOx are firstly stored on the catalyst, which is …

As the most promising strategy so far for NOx abatement of lean engines, Nitrogen oxide
Storage and Reduction (NSR) catalysts can greatly reduce gas consumption as well as the …

There is currently a need for a practical solution for NOx abatement in automotive diesel
engines. Technologies developed thus far suffer from inherent technical limitations. The …
