ABSTRACT:
A system for measuring amounts of particulates exhausted from a vehicle internal combustion engine, such as a diesel engine, has a dilution tunnel into which exhaust gas is introduced and mixed with and diluted by clear air. One part of the diluted gas is introduced into a first sampling arrangement in which a first filter is provided for collecting particulates of dry soot and another part of the diluted gas is introduced into a second sampling arrangement in which a second filter is provided for collecting particulates of soluble organic fraction (SOF). The amounts of dry soot and SOF are calculated in a real time manner in accordance with the pressure drops across the filters on the basis of the time differential of the signals output from pressure transducers provided for each filter.
