The Blow-By Test Rig BBT 143 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 GMS 141 with the speed of an optical concentration measurement of the Process Aerosol Photometer PAP 610.
Due to the design of the blow-by test rig and of the stand-alone devices, these measurements can be performed very efficiently at engine test stands. Combining the Gravimetric Measuring System GMS 141 with the Process Aerosol Photometer PAP 610, oil consumption measurements for engine characteristic maps can be performed with minimum efforts and time.
Additionally, the Process Aerosol Photometer PAP 612 provides the opportunity to measure oil films and oil gushes in pipes e.g. at tilt test stands.
