催化柴油微粒过滤器

Since about 2005, particulate filters have been generally used with modern diesel engines to remove diesel particulate mater. The ceramic wall flow filters almost completely remove the carbon particulates over a wide range of engine operating conditions.

Since the continuous flow of soot into the filter would eventually block it, it is necessary to 'regenerate' the filtration properties of the filter by burning off the collected particulate on a regular basis. Therefore, the exhaust temperature in Diesel passenger car applications is frequently increased until collected soot is burned off. In order to reduce the burn-off temperature, the filter is usually coated with an oxidation function.

Deferry®'s CDPF(Catalysed diesel particulate filters) are the solution for diesel particulate matter control >95% PM filtration efficiency and low regeneration temperature are achieved through the combination of wall flow type ceramic honeycomb with patented catalyst formulation. In additional of PM reduction, catalyzed diesel particulate filter is also reducing carbon monoxide and hydrocarbon from engine exhaust stream.
Current product offer covers from1.66 liters (4.66x6") to 43.42 liters (15”x15") as a single CDPF which would be perfect solution for diesel engine displacement from 1.5 to 40 liters.

Key characteristics of Deferry®'s CDPF include:
1).Low pressure drop
2).Excellent performance
3).Self-regeneration
4).Can be applied to on-road and off-road diesel engines
5).Can be provided in a standard or custom configurations

6). The materials of substrate include cordierite and silicon carbide.
