Our main pages on this subject:

1.	NOx Trap
	Renault has filed 36 patents for its NOx Trap.The new NOx Trap with catalytic converter has a dual function : - the traditional function of oxidising hydrocarbons (produced by partial combustion) and carbon monoxide (produced by partial combustion due to a lack of oxygen) ; - the treatment of nitrogen oxide (produced by the combustion of diesel fuel at high temperatures)..

2.	Preserve air quality
	Catalytic converter... By fitting its gasoline cars with catalytic converters, Renault achieves close to a 99 % reduction in the concentration of carbon monoxide (CO) and nitrogen oxides (NOx) in exhaust fumes.... The oxygen probe measures the oxygen concentration in the exhaust fumes to optimize operation of the catalytic converter....

3.	Build for the future
	Renault keeps one step ahead of increasingly tough regulations on pollutant gas emissions, with developments like the NOx trap, which further improves on the catalytic converter's function of cutting down NOx emissions....
