Daimler announced that it will be spending €3 billion ($3.35 billion) for a clean diesel technology. The company aims to reduce the diesel exhaust pollutants of its vehicles through a software update. The upgrade will affect the engines and exhaust systems of its units.

According to Reuters, the overall investment already includes the €2.6 billion disclosed by the company in February this year.

Daimler will install its diesel autos in Europe with selective catalytic reduction (SCR) technology. Then it will offer particulate filters for gasoline-fed units.

The parent of Mercedes-Benz said the enhancements in the engine technology covers the optimization of turbocharging plus fuel injection and intercooling. Furthermore, the application of new materials which target to extend the exhaust-gas recirculation treatments at lower operating temperatures will be included.

Based on a related report of Inautonews, the company will utilize the SCR on the compact front-wheel drive cars of Mercedes. It will be used to replace the existing exhaust systems of the brand that takes in nitrogen oxide, which is later converted to smog. The source noted that Mercedes currently use SCR systems that require Adblue injection units in its larger models.

Aside from the clean diesel technology investment, Daimler also revealed that it will spend $561 million this year in relation to the recall of faulty Takata airbags in order to ensure the safety of its customers. The article claimed that Daimler would need to recall approximately 200,000 vehicles in December 2019 too as a precautionary measure in US and Canada despite saying that it was not aware of any defective cars in the said areas.
