CT 159.02 Exhaust Gas Analysing Unit
Education / GUNT Hamburg / Thermal Engineering and HVAC / Internal Combustion Engines /

The CT 159.02 is an accessory for the CT 159, CT 110, CT 300 and CT 400 engine test stands and the associated engines. The unit can be used to measure the exhaust gas composition (CO, CO2, HC, O2), the excess air factor λ and the oil temperature in the engine. The menu-based display on the unit is used for calibration, operation and to display the measured data. Interfaces allow it to be connected to a PC or external printer. The measuring accuracy complies with OIML Class 1 (Organisation Internationale de Métrologie Légale) and meets the requirements of the Physikalisch-Technische Bundesanstalt (German national metrology institute; PTB).


Learning Objectives / Experiments

- Measurement of residual oxygen content in exhaust gas
- Measurement of carbon monoxide and carbon dioxide
- Measurement of hydrocarbons
- Determination of lambda (fuel-air ratio)
