FRANKFURT — Daimler has temporarily halted deliveries of a lorry engine after anticipating that, in certain pushing conditions, a emissions of nitrogen oxide (NOx) could surpass authorised limits, a association pronounced on Sunday.
Daimler, responding to a news in a Bild am Sonntag newspaper, pronounced it had sensitive Germany’s Federal Motor Transport Authority (KBA) of a emanate final month and was in a “constructive” dialogue.
German automakers have been underneath heated inspection given a Volkswagen Group in 2015 certified to regulating bootleg program to lie emissions tests.
VW Group reached a multi-billion-dollar allotment in a United States, though a liaison continues to resonate in Germany, where a conduct of a Audi unit, Rupert Stadler, has been arrested in a apart investigation.
Daimler is also underneath inspection over how a diesel automobile engines use a urea nitrate additive, called AdBlue, to vacate emissions of nitrogen oxide, that can minister to a arrangement of damaging fog and ozone.
Germany’s Transport Ministry pronounced final month that 774,000 Mercedes-Benz vehicles in Europe had been found to enclose unapproved supposed “defeat devices” and systematic Daimler to remember 238,000 cars in Germany.
In a latest case, Bild am Sonntag reported that Daimler had found during inner checks that program using a OM 501 lorry engine would, in certain circumstances, stop a injection of AdBlue.
In a statement, Daimler pronounced a news was dubious and that a engine’s on-board diagnosis complement was designed to switch off a upsurge of AdBlue in surprising resources such as when a engine was using on biodiesel.
This would forestall extreme injections of AdBlue heading to a recover of ammonia, that in high concentrations can act as a respiratory irritant.
“In a march of regulator tests, Daimler found removed situations when a six-cylinder heavy-truck engine of a Euro 5 customary somewhat exceeded a applicable NOx limits,” a association said.
Daimler pronounced it had undertaken a minute research of a commentary and sensitive a KBA during a finish of June.
The engine was sole in Mercedes-Benz trucks in Europe until 2013. It is now on sale usually outward Europe. “Until a technical issues are clarified, a association has taken a precautionary preference no longer to broach this engine,” Daimler said.
