A method for studying fuels based on crude oil and of motor oils on biodiesel contamination

摘要

It is a method for detecting of contamination of a conventional fuel based on petroleum, which is used in an internal combustion engine, is provided. A sample of engine oil, by means of a polar solvent in a polar component and separated into a not polar component. The polar component is determined in relation to one or more chemical biodiesel was parts selected from the group consisting of plants ter an, fatty acid methyl esters, cetan, and mixtures thereof, which represent a degree of the engine oil contamination analyzed. The polar and non-polar component may be added by gas chromatography and mass spectrometry (gc / ms) and optionally by flame ionization detection (fid) with respect to one or more chemical biodiesel was parts are examined, which results in a semi-quantitative amount of such chemical biodiesel was parts can deliver. Force of the fabric samples can also be for biodiesel contamination species by means of gc / ms be examined.
