As part of an international alliance, the Diesel Systems Division develops, applies and manufactures diesel systems which contribute to making vehicles cleaner and more economical. At the same time, our systems serve as the basis for making the diesel engine a more sporting and enjoyable power plant. As the world's leading manufacturer of diesel injection systems, we have the perfect system for every customer and every application available.

In order to ensure compliance with the stricter emission standards that are being implemented around the world (such as the US07 standard in the U.S.), we are developing exhaust gas treatment systems for cars. In 2004, we began manufacturing the Denoxtronic metering system for commercial vehicles. This system injects the reducing agent Adblue into the exhaust gas flow. We now also offer Departronic, a further metering system for commercial vehicles. This injects diesel fuel into the exhaust gas flow, thus facilitating the regeneration of particulate filters. In 2006, we agreed to set up a fifty-fifty joint-venture company with Denso Corporation of Japan, which is expected to commence manufacturing of ceramic elements in eastern Europe in 2009. These will be used in diesel particulate filters.
