Daimler AG says it has stopped delivering trucks equipped with certain 6-cylinder diesel engines that can violate emission limits for nitrogen oxides, Reuters reports.
The engine was used in Mercedes-Benz trucks until 2013 and continues to propel some of the brand’s commercial trucks sold outside Europe. Daimler says it has suspended deliveries until unspecified technical issues are clarified.
The problem involves the engine’s AdBlue urea injection system, according to Bild am Sonntag. The technology sprays urea into the exhaust stream to help eliminate NOx emissions.
Daimler acknowledges the system may “slightly” exceed NOx limits under “isolated” conditions. The company says it conducted an internal analysis and turned over the results to Germany’s Motor Transport Authority (KBA) at the end of June.
Last year the European Commission began investigating suspicions that BMW, Daimler and Volkswagen manipulated their urea injection systems at the expense of emission levels to extend the intervals at which owners must refill the system’s urea tank.
