Summary:

In the future, similar to passenger cars, newly registered European heavy duty vehicles shall be labelled with the fuel consumption in typical driving cycles, determined at standardised conditions. This shall improve the comparability of the vehicles and motivate manufacturers to apply more fuel-saving technology. Therefore, a multi-stage certification procedure has been developed by a consortium of European laboratories under the leadership of the Institute for Internal Combustion Engines and Thermodynamics of TU Graz. It is based on a simulative approach and consists of: On-road measurement of driving resistances; determination of drivetrain losses; power demand of engine auxiliaries and other consumers; generation of an engine fuel consumption map from the engine's type approval tests; development of several driving cycles, typical for different vehicle applications; and a proposal for a calculation method of fuel consumption. In this contribution, a short overview of the whole project, a comparison of the simulated and measured fuel consumption of test vehicles and an outlook to the future of the type approval method are given
