Introduction
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
