In order to remove insoluble particulate matter from the exhaust gas, particulate filters are necessary. Particle filters operate by retaining particles, and then burning them in order to clean the filtering elements. Problems that occur during the construction and operation of filters are:
the size of the particles (mostly less than 1 μm),
soot ignition temperature without a catalytic converter (in the filter and/or fuel) is about 550-600°C, the burn-out temperature of can exceed 1000°C,
very high hydrocarbon emissions during burn-out (regeneration of the filter),
increased flow resistance due to the deposition of particulate matter on the filter during engine operation.
