Environmental issues have a significant influence on the development of modern combustion engines. Particularly the tightening of emission limits in Europe and the USA have to be considered in the development process. One issue that influences the emissions of engines is the oil consumption of the engine and thus the reduction of the oil consumption of combustion engines has gained importance in recent years. In order to optimize the oil consumption of the engine a measurement technique is needed that allows a very accurate detection of the engine oil consumption for steady state as well as for transient engine operation points. Since conventional measurement techniques provide only limited accuracy at long measuring times and are only applicable for steady state engine operation new methods for the online detection of the engine oil consumption have to be established. New methods for the oil consumption measurement are the tracer methods.
