PM Catalyst, Efficient Emissions Technology
The PowerStar meets Tier 4B emissions Regulations by using advanced PM (Particulate Matter) Catalyst technology. This is a simple, flow through particulate filter that captures soot, contained in exhaust gas, and passes it through the PM Catalyst and, when it touches the walls, it is burned off. The end results is the filter does not block due to the high flow of exhaust gases and will not require the regular regeneration that occurs with a DPF (Diesel Particulate Filter).
