Particulate filters
AWG POLONEZ
AWG Polonez has introduced a catalytic metal block made of perforated strip – the IMS block – to the domestic and European market. The difference between the new IMS catalytic block and the structures that are currently in use worldwide is that the gases are mixed within the block and do not flow freely through open channels. The exhaust particles move through the different layers of the spiral. This results in better (more regular) contact with the particle surface. The IMS can be used in petrol and diesel vehicles and is widely used in particulate filters.
Increasing emission requirements, including in diesel engines, have forced car manufacturers to use diesel particulate filters (DPFs), designed to clean soot from the exhaust gases.
