With the introduction of tightened limits of particle numbers beside particle mass emitted new pollution control devices like catalyzed gasoline particulate GPF filter is required.

Katcon has gained an understanding of the challenges faced by GPF technology at calculation method and stuffing techniques evaluated at our own Advanced Engineering Laboratories for evaluations on how to hold a GPF substrate in place in the canning process and during operation, without a risk of substrate failure


Analysis and Comparison pressure exerted on the brick with hard or soft stuffing technique. Potential data generation for canning durability and ash storage relation to backpressure. 


Backpressure measurements of GPF canning at various temperatures levels.  Step stress evaluation to find damaging factors on structure or displacement findings. 


Thermal shock test upon test cycles completion, also including brick location and  structural integrity inspection.
