- Abstract:
- Worldwide there are great efforts to reduce the CO2 emission into the atmosphere by using fuels made from biomass. These biofuels are normally blended with fossil fuels.
For legal metrology the thermal expansion coefficient, the so-called temperature conversion factor, is of great importance to guarantee correct measurements of the fuel volume. Thus, the density of fossil fuels blended with biofuels was measured at the Physikalisch-Technische Bundesanstalt (PTB). Investigations were performed on mixtures of fossil petrol with ethanol and of fossil Diesel with biodiesel.
The volume concentration of the biofuels component varied between 0 % and 100 % in order to have data available for all possible mixtures. The data were measured in a temperature range between -10 °C and +50 °C. - Keywords:
