retrofitting of diesel cars. the upgrade of catalysts and the unregulated metal katlysoren constitute a functional unit for the reduction of nitrogen oxides (nox).the oxides of nitrogen (nox) must be reduced.

摘要

problem no 1, stickstoffdioxidepollutant emissions: older diesel vehicles are major contributors to the nitrogen oxide pollution in inner cities. the blue badge, threatening the environmental standards.solution to the probleminstead of driving bans is a technical solution to improve the air quality in cities. my invention is a solution to reduce the nitrogen oxide pollution.the existing catalyst is a catalyst, and the upgrade unregulated metal catalysts).the exchange catalyst must be certified and with blue angel award.
