Why do some aftermarket trucks pass emissions tests seamlessly, while others keep failing and throwing fault codes?
The answer lies in whether the core design matches the specific regulation and duty cycle. A “one-size-fits-all” substrate simply won’t work:
For North American Long-Haul (EPA 10/17): Higher and steadier exhaust temperatures demand superior thermal durability, optimized coating formulation, and lower backpressure to maintain fuel efficiency over millions of miles.
For European Urban Delivery (Euro VI Step E): Frequent stop-and-go driving keeps exhaust temperatures low. This requires faster low-temperature catalyst activity and precise cell density design to prevent DPF clogging and premature failure.
At Xichuang, we don’t just replicate dimensions; we replicate and optimize performance. By aligning our DPF, DOC, and SCR systems with exact OEM coating strategies and vehicle duty cycles, we ensure:
Zero fault codes & no black smoke
Perfect fitment & instant installation
Excellent conversion efficiency matching Euro 5/6 & EPA10 standards
