Nitrogen oxide

Our main pages on this subject:

1.	NOx Trap
	The NOx Trap fits firmly with Renault's determination to reduce pollutant emissions.This chemical process captures harmful nitrogen oxides, then converts them into neutral gas.. This post-combustion system will be available from September 2008 in France and Germany in private fleets of 2.0 dCi Renault Espaces..

2.	Preserve air quality
	Renault developed its EGR system to cut down the production of nitrogen oxides (NOx) during the fuel combustion process.... 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....

3.	Build for the future
	Homogeneous Charge Compression Ignition (HCCI) diesel engines and Controlled Auto Ignition (CAI) gasoline engines reabsorb a proportion of the burned exhaust gases to perform " cold " combustion and thus achieve near-zero soot and nitrogen oxide emissions.... Nitrogen oxides (NOx) trap...

4.	2.0 dCi (M9R)
	Result : lower nitrogen oxide (NOx) emissions ; a self-regenerating particulate filter with exhaust-post injection on the 175 hp version :...
