Development and Application of a New Mass Spectrometer Based Measurement System for Fast Online Monitoring of Oil Emission in the Raw Exhaust Gas of Combustion Engines 2002-01-2713
An increasing environmental consciousness as well as the awareness for sustained preservation of natural resources causes new regulations for emissions and great efforts for fuel economy and increasing oil service intervals. For a better understanding of the process generating pollutants, the emissions of every phase of the combustion cycle have to be monitored online. Moreover, it is important to measure the raw exhaust gas during different driving cycles and investigate the influence of different parameters as for example changing engine operating conditions.
The new mass spectrometer (MS) based measurement system allows the direct detection of unburned gaseous oil HC without tracers. The gas inlet system enables crank angle resolved monitoring of different raw exhaust gas compounds in the exhaust manifold or directly in the cylinder. By an integrating method a complete engine map of oil consumption (72 points of operation) is received in one day instead of several weeks with conventional methods.
