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 …

There is an increasing interest in running gasoline fueled passenger cars lean of
stoichiometric air to fuel (A/F) ratio to improve fuel economy. These types of engines will …

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 removal of nitrogen oxides (NOx), which are major atmospheric pollutants, in exhaust
gas after-treatment systems, has been studied extensively. The catalytic reduction of NOx in …

Comparing the stoichiometric engines, lean burn gasoline and diesel engines are normally
more fuel efficient, resulting in longer travel distances per unit of fuel and thereby reducing …
