Catalytic converters with high cell density substrates (600-1200 CPSI) are game-changers for emission control. By packing more channels per square inch, they maximize surface area, boosting conversion efficiency of NOx, CO, and hydrocarbons—critical for meeting Euro VI/China 6 standards.
But why aren’t they everywhere?
Backpressure Trade-off: Ultra-high density risks increased exhaust backpressure, demanding precise engine calibration.
Manufacturing Complexity: Thin-wall ceramics require advanced coating tech to ensure durability and avoid cracks.
Cost vs. Benefit: Higher material and production costs challenge cost-sensitive markets.
At JIETE, we tackle these hurdles with hybrid designs (graded-density substrates) and AI-driven coating uniformity control. For OEMs aiming to future-proof emissions systems, the right balance is key.
