W-System with Exchangeable Cartridges

Functional Principle of the W-System

The W-system consists of an exhaust inlet chamber that is installed at the vehilce. Furthermore the filter cartridges and the external regeneration oven are part of the system. The W-system is ideal for engines up to 100 kW performance. In case a twin-system can be installed the engine performance is raised.

The cartridges contain a Silicon Carbide (SiC) ceramic for soot filtration. The soot load increases the backpressure which is measured and monitored by a manometer. When the maximum backpressure level is reached, the cartridge is dismounted from the exhaust inlet by opening the quick fastener clamp. The cleaning is done on the external oven.

In the meanwhile the vehicle can be operated by using another cartridge. Especially when multiple vehicles are equipped with the W-system and share the oven for regeneration the system pays off.
