Each diesel particulate filter we develop is tested on a

• Flow bench

to determine its flow properties. Additional durability tests are carried out taking the effect of temperature and exhaust gas into account on the

• Hydropulse test rig (including hot gas)

Bench tests are conducted on different

• Engine test benches and on
• Chassis dynamometers for passenger cars

Modern tools such as

• CAD and CAM

are also used to progress rapidly from the development concept to

• Prototyping,
• Design,
• Sample production

followed by bench tests, more in-depth tests and field tests on the vehicle to ultimately achieve a product that is ready for series production.
