Standards:

(1) ISO 8178: Reciprocating internal combustion engines – Exhaust emission measurement (2) SAE J1667: Crankcase blow-by measurement methods (3) ISO 6145 series: Gravimetric measurement of aerosols (4) EN 1822/ISO 29463 principles: for aerosol particle measurement

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

Product Information:

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

Features

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

Technical Data

Accessories

differential pressure compensation

flat sheet filters

Maintenance Information

Regularly inspect and replace flat sheet filters to avoid clogging and maintain measurement accuracy.

Check compressed air supply and pressure compensation unit for proper operation before each test.

Clean optical components of the photometer to prevent signal interference from deposits.

Calibrate gravimetric and optical measurement systems periodically to ensure accuracy.

FAQ
