A Bosch spokesperson said:<\/strong> \u201cIt means diesel is therefore still an affordable alternative for urban traffic and in the future will be an ecologically sound one too.\u201d<\/em><\/p>\u201cThanks to new test procedures and engineering ingenuity from Bosch, a decisive technological breakthrough has now been achieved with regard to improving air quality.\u201d<\/em><\/p><\/blockquote>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\nBosch engineers have succeeded in achieving average NOx emissions of 13 mg\/km during drives on roads with urban, rural, and freeway elements.<\/p>\n\n\n\n
With the current state-of-the-art exhaust technologies from Bosch, vehicles are capable of emitting only very little NOx while still preserving the diesel engine\u2019s renowned efficiency.<\/p>\n\n\n\n
How it works<\/strong><\/h4>\n\n\n\nThe new technology includes a rapid-response air management system and sophisticated thermal management of the exhaust-gas treatment system.<\/p>\n\n\n\n
A combination of high and low-pressure exhaust gas recirculation makes the air management system even more flexible.<\/p>\n\n\n\n
Bosch has also found a solution in which the starting temperature barely has an effect on emissions anymore.<\/p>\n\n\n\n
By establishing a smart link between the engine and exhaust-gas treatment system, the exhaust system stays warm enough and can do its job reliably, even in city driving.<\/p>\n\n\n\n
An external engineering company analysed the emissions data collected at the Neckartor in Stuttgart.<\/p>\n\n\n\n
After applying a variety of computational models, it concluded that if diesel vehicles equipped with the latest technologies replaced the current diesel fleet, diesel engines would only be responsible for a negligible portion of the relevant ambient air contaminants<\/p>\n\n\n\n
