Characterisation of flow meters for fuel consumption measurements in realistic drive cycle tests
Abstract
Type approval testing of vehicles on chassis dynamometers, or experiments at the engine tests bench, require a precise measurement of the time-dependent fuel consumption, that is usually carried out by means of flow meters. However, the performance of these instruments can be jeopardized considering both the range of flow rate and its high dynamicity. In addition, the adoption of innovative fuels, such as biofuels and synthetic fuels, is nowadays of increasing interest thanks to their potential in pollutant emission reduction. Therefore, flow meters should depend as little as possible on the selected fuel, e.g. density and viscosity, and fuel temperature, guaranteeing high measurement accuracy in each test condition. In this context, the scope of the ongoing EMPIR Joint Research Project 20IND13 “SAFEST” is to investigate the measurementaccuracy of flow meters considering different fuels and different highly dynamic operating conditions. More specifically, in this paper the analysis on a Coriolis flow meter is presented. Flow measurements were carried out using different fuels in a wide density and viscosity range along with a broad temperature range.
