The Cambustion Diesel Particulate Generator (DPG) offers a diesel-fueled alternative to an engine for conducting diesel particulate filter (DPF) testing. The DPG includes features that ensure repeatable loading conditions. To avoid a pressure increase upstream in the burner as the DPF fills, the system uses a vacuum blower downstream of the DPF, which allows the DPF inlet and burner to remain at atmospheric pressure during loading. It has low NOx output, avoiding passive regeneration by NOx. The system includes data recording of up to 16 thermocouples, filter delta P, and all controlled system parameters. It can regenerate filters with inlet temperatures as high as 800ºC, and maximum soot load tests can be performed to study filter durability. In addition to development work, the DPG is suited to quality control work: By defining pass/fail efficiency and backpressure criteria, it can be used to simplify batch testing of production DPFs.For more information, visit booth 1608 at the SAE 2009 World Congress.
