MULTIPLE OIL-EMISSION MEASURING DEVICE FOR ENGINES

A multiple oil-emission device for hydrocarbon emissions in an exhaust-gas mixture, comprising an exhaust-gas probe, which has a transfer capillary, and a measurement channel, which has an ion source and a filter apparatus having a measuring apparatus. The transfer capillary has a drop-catching apparatus at the tip of the transfer capillary, which drop-catching apparatus comprises a short throttle segment and a transfer segment, which adjoins the throttle segment in a flow direction and is at least ten times longer. The measuring apparatus is connected to an analysing apparatus, which comprises a classifier for vaporous oil constituents and oil constituents in the form of drops. The classifier makes possible a differentiation between vaporous constituents and constituents in the form of drops, which makes robust and accurate determination possible regardless of the operating point because of the collection of constituents in the form of drops.
