Method of measuring the oil consumption of internal combustion engines

摘要

A method is provided for measuring the oil consumption of an internal combustion engine equipped with an exhaust gas line. The oil is radioactively labeled with a radioactive tracer. The exhaust gas is examined for the contents of the tracer with at least one first sample taken from the exhaust gas stream. The exhaust gas stream has oil added to it corresponding to the oil in the internal combustion engine. Subsequently, at least one second sample is taken from the exhaust gas stream downstream of the point of addition and a comparison is made between the contents of radiotracers of the first and second samples. A device for practicing the method is provided.
