WebApr 14, 2024 · For the Chinese application, after the four-mode aging, it was found that the CC1 TWC catalyst volume should be greater than 1.0 L. High levels of OSC were needed in the GPF to meet CO and NOx emission targets. For the European application, after fuel cut aging, Euro 6d emissions were met with any combination of TWC and GPF catalysts. Web“Add On” GPF Systems Pressure Drop – Impact of GPF Design A range of materials, microstructures and designs have been screened to optimize the GPF for “add on” systems • Due to low expected soot loads lower cell densities are favored for “add on” systems • Reduction in pressure drop can be achieved by thinner wall designs

WebGPF costs. Based on an assessment of production costs for two GPF designs, we estimate for a 2.0L gasoline engine a cost of $106 for a stand-alone GPF and between $114 and $154 for a four-way catalyst, presented here as a three-way catalyst (TWC) with PM trapping capabilities.
