Exhaust emissions of tractors under real conditions are difficult to measure and have barely been researched. With the presented method of practical tractor driving cycles (PTFZ) real-world engine operation can be simulated conveniently on the entire tractor system at a test stand. This allows efficient measurement of exhaust emissions under repeatable conditions regardless of weather conditions and implement. The method can also be used to develop low-emission and climate-friendly drive systems.     «
