Bosch's popular diesel engine software was not preprogrammed to cheat

A favorite diesel engine management system used by several top automakers, including Volkswagen AG, had not been preprogrammed to detect whenever a vehicle was undergoing lab emissions testing, according to the Oughout. S. Environmental Protection Agency and a previous EPA official.

Instead, NOVA had the engine software program modified to turn on the vehicle's emission control system with regards to was being tested in the laboratory, on a rolling test mattress called a dynamometer, then transform it off when the vehicle had been on the road, the EPA stated.

Daimler AG's Mercedes-Benz, that uses the same engine management made by German supplier Robert Bosch GmbH, said later Tuesday that its diesel powered cars "are not when you have software that can tell that this vehicle is on a examination rig. "

BMW AKTIENGESELLSCHAFT, also a customer of Bosch's engine software, said upon Wednesday that its emissions control systems are energetic both on the test bench and the road.

Volkswagen has recognized that it modified the motor software to circumvent Ough. S. emissions standards. Upon Wednesday, the company did not react immediately to a request for opinion.

Because Bosch provides the powerplant control module, called EDC17, and basic software for almost all the four-cylinder diesel vehicles sold in North America, lawmakers prying the Volkswagen scandal possess raised concerns that it will be easy for other manufacturers in order to also circumvent state as well as federal emissions rules.

Proof that basic software for example that supplied by Bosch might be easily modified by a good automaker to detect labrador testing conditions could also increase questions about whether the You. S. needs to change the lab-based emissions testing routine, according to a congressional assist close to the House Energy and also Commerce Subcommittee on Oversight and Investigations.

A someone for the U. S. Epa said: "It is not correct that standard automotive application detects when a vehicle is actually on a dynamometer. "

Bosch said in a statement in Tuesday that it supplies elements such as engine management techniques to automakers' specifications, which "how these components tend to be calibrated and integrated into total vehicle systems is the obligation of each automaker. "

It is far from clear exactly what role Bosch played, how closely this worked with Volkswagen to modify the actual engine management software, and just how much it knew regarding Volkswagen's intentions to use computer software in order to cheat on emissions standards.

Bosch declined to be able to comment on the questions, stating its business relationships along with customers were confidential also it could not divulge details.

Bosch also warned VW within 2007 that it would be unlawful to use its basic serp management software for besides testing purposes, the German born newspaper Bild am Sonntag reported last week.

The ENVIRONMENTAL PROTECTION AGENCY on Sept. 18 revealed VW's scheme to intend to circumvent federal emission requirements with the special software. VOLKSWAGEN eventually admitted that the program was installed on 11 mil vehicles from 2008-2015, such as nearly 500, 000 within the U. S. and more compared to 8 million in European countries.
