Performance Testing and Field Evaluation of an In-Line Full-Flow Particulate Trap System for the DDC 6V-92TA Two Stroke Engine

Particulate control technology for heavy-duty diesel engines is of increasing interest. This paper describes a fully automatic, in-line full-flow Burner Diesel Particulate Filter System developed by Kloeckner-Humboldt-Deutz AG (KHD). The system was fully optimized in a transient test cell by ORTECH International for the Detroit Diesel 2-stroke 6V-92TA engine.

The important parameters such as the fuel coefficients and exhaust backpressure coefficients were developed in the test cell. Transient emissions tests were conducted showing approximately 85% particulate trapping efficiency. The trap operated fully automatically. Regeneration was triggered when the exhaust backpressure had exceeded a predetermined level for a cumulative period of 3 minutes. The regeneration process on average took approximately 7-½ minutes to complete. The frequency of regeneration was approximately once every 4 hours.
