What are the Challenges Associated with Catalytic Particulate Filters?
Despite their advantages, catalytic particulate filters face several challenges:
Cost: The use of precious metals in catalytic coatings can significantly increase the overall cost of the filter. Poisoning: Contaminants such as sulfur and phosphorus in the fuel or lubricants can poison the catalyst, reducing its effectiveness. Thermal Management: Maintaining optimal temperatures for effective regeneration without damaging the filter is a complex task.
