Test medium for the rapid analysis of engine oils in internal combustion engines

摘要

The present invention relates to a test medium for the rapid analysis of engine oils in internal combustion engines, having a weight per unit area of 50.0 to 200.0 g/m2, comprising, based on the total weight of the test medium, 20.0% by weight to 98.0% by weight of cotton pulp, 0.0% by weight to 50.0% by weight of cellulose and 0.1% by weight to 50.0% by weight of silicic acid and/or at least one silicate salt. The present invention also relates to a method for the rapid analysis of engine oils in internal combustion engines, in which a drop of an engine oil to be analyzed is applied to the test medium according to the invention and is allowed to penetrate into the test medium, and the text result is then preferably compared with at least one reference image in order to determine the condition of the engine.
