Sensor system for long-term analysis of fuel vapour restraint systems

Abstract
Since 2011 gasoline is blended with bioethanol (5-10 Vol.-%) to comply with the biofuel quota required by law. To examine the influence of the bioethanol additive on the functionality of the fuel vapour restraint systems a suitable test facility is designed. This test facility enables automated long-term tests lasting several weeks. As a result, the adsorption behaviour of the activated carbon filters is examined by the used sensors for multiple ad- and desorption cycles even in case of multicomponent mixtures.
