Abstract:
This study evaluates the potential of CNG propulsion systems for long-term operation. For this purpose, light and medium duty vehicles as well as passenger cars with very different service performance were investigated under real-world conditions. The research also includes tests of a vehicle with natural gas and bio-methane to assess the effects of the energy supply on the performance. The demonstration and evaluation of CNG operational fleets with higher mileage provide a sustainable monitoring of clean propulsion systems based on innovative real-world in-car measurements. A benchmarking to the same passenger car with diesel powertrain was done as well. For a consistent comparison of the different test vehicles, the results for each drive test are presented as emission rates versus the mean vehicle speed.
