Size Determination of the Ceramic Diesel Particulate Trap

A method for the determination of the size of the ceramic trap according to the engine and its use, has been developed. The calculation algorithm is presented, based on fundamental considerations concerning trap operation during regeneration and accumulation, and taking into account the parameters imposed by the engine.

The application of the method is then presented, with the example of engines from within the range of 30-300 kW rated power. A module configuration of the trap oxidiser consisting of a number of Corning EX 47, 5.66″ × 6″ filter elements is used.
