Solution of High Back Pressure on Truck Exhaust Treatment Substrates
Solutions: Regularly clean or replace DPF/SCR substrates. Inspect the exhaust system for blockages or damage. Avoid prolonged low-speed driving to ensure proper DPF regeneration. Summary: Excessive back pressure damages substrates,…
Impact of High Back Pressure on Truck Exhaust Treatment Substrates
1. Substrate DamageCracking or Breakage: High temperature and pressure can cause ceramic substrates (e.g., DPF, SCR) to crack or break. Increased Clogging: High back pressure leads to particulate matter (PM)…
Thedifference between single-core and multi-core.
The single-core and multi-core designs of metal substrates are primarily based on exhaust flow requirements and spatial constraints. The single-core structure is simple and cost-effective, making it suitable for small-displacement…
Daily Science – Metal Carriers
The metal substrate features a honeycomb structure made of heat-resistant alloys (e.g., FeCrAl) with ultra-thin walls (~0.05mm). As exhaust flows through, platinum/palladium catalysts convert CO and NOx into harmless gases…
Why Do the Patterns on Both Ends of a DPF Substrate Differ?
The patterns on the two ends of a Diesel Particulate Filter (DPF) substrate are designed differently to optimize filtration performance, airflow distribution, and mechanical strength. Here are the key reasons:…
