Test system for the characterisation of the oil content in blow-by gases at engine test systems

Test system for the characterisation of the oil content in blow-by gases at engine test systemsThe Blow-By Test System is a compact measuring system for the determination of the oil droplet content of crankcase gases (blow-by) at engine test rigs.

It combines the precision of a gravimetric measurement of the Gravimetric Measuring System with the time resolution of an optical concentration measurement of the Process Aerosol Photometer.

Additionally, the Process Aerosol Photometer provides the opportunity to measure oil films and oil gushes in pipes e.g. at tilt test stands.

Applications

determination of oil content in blow-by on the engine test stand

evaluation of oil mist separators on the engine test stand

on-line concentration monitoring of oil mist aerosols

Benefits

time-saving and reproducible determination of oil content in blow-by gases

measurement in the full flow of the blow-by up to 300 l/min

compensation of the differential pressure from gravimetric sampling

high resolution and rapid measurement from optical inline measurements

integration into engine test stands
