Measurements of fuel consumption and emissions of gaseous pollutants in vehicle exhaust during realistic conditions in real traffic, are of vital importance for e.g. validation of emission models and for obtaining data on cold start effects. The VTI experimental car with installed apparatus for real-world measurements of exhaust emissions and fuel expenditure was driven after a cold start around a 16,7 km long urban driving course. Reproducibility of driving pattern, emissions etc. proved to be excellent for repeated runs. Emission and fuel factors were compiled from the measured data for the initial cold phase lasting 3-4 minutes and for the slightly less than 29 minutes of warm driving. From these data cold start emissions were calculated: Fuel consumption (dm3/cold start): 0,066 (0,044). Nitrogen oxides (g/cold start): 0,600 (0,420). Hydrocarbons (g/cold start) 3,564 (0,505). Uncertainty measures on the 95 % level are given in parentheses. The start emissions cited are of similar magnitude as the values reported earlier using data from chassis dynamometer measurements.
