Engine exhaust gas sampling for mass spectrometer real time oil consumption measurement |
| abstract |
An engine oil consumption measuring system includes a multi-cylinder engine with an exhaust system positioned in a test cell. A sampling probe has an end positioned in the exhaust system to receive exhaust. A sample transfer apparatus includes a first end fluidly connected to the sampling probe and a segment positioned in an interior of a furnace. A mass spectrometer includes a specimen probe with an inlet positioned in the segment of the sample transfer apparatus. A particulate filter is positioned in the segment of the sample transfer apparatus upstream from the inlet of the specimen probe. The sample transfer apparatus and the furnace are maintained at temperatures above an oil condensation temperature during testing. |
