To reduce engine emissions caused by evaporation of oil, the investigation of this process in the combustion chamber is necessary. In order to understand the mechanisms of oil emission, the gas composition has to be monitored online for each combustion cycle. A mass spectrometer equipped with a new direct inlet-system optimised by computational fluid dynamics enables crank angle resolved monitoring with a rise time of 2.5 ms over the full speed-/torque-range of a spark-ignition engine. The allocation of the measurement data to the crank angle is calculated by a new software program based on a genetic algorithm using CO2 measurements and a model of the combustion process.
