During recent years, many measurements on chassis-dynamometers have already incorporated the online measurement of emission concentrations at the exhaust as standard alongside usual average values. These modal-collected data can be combined with the likewise modal-recorded operating condition of the vehicle (engine load) and serve as a basis for methods for calculating emissions. A reliable emission data set gives the possibility of calculating emissions for different real-world driving conditions. For many applications, it is thus no longer necessary to carry out costly and time-consuming chassis-dynamometer tests. Generation of emission data sets takes place on chassis-dynamometers using different driving patterns. Systematic investigations should show whether and how differing parameters (e.g. driving patterns) affect the accuracy of the emission calculation for real-world driving conditions. The report presents partial results of the 'Instantaneous Vehicle-Emissions' project, which is itself part of the 'MEET' project (Methodology for Estimating Air Pollutant Emissions from Transport). MEET is a project within the framework of the 4th European Research Framework Programme.
