Summary

Global efforts to reduce CO₂ emissions and current limitations of fleet consumption force the development of more efficient power trains. In addition to the continuous improvement of gasoline and diesel engines, a greater CO₂ reduction is also possible through the use of fuels with a lower C/H ratio. In this context, methane is a promising approach because of the low carbon content, a reduction of CO₂ emissions is achieved by more than 20%. Furthermore, methane in motor mode provides efficiency-enhancing features such as high knock resistance, wide flammability limits and better mixture formation. As part of a research project at the Institute for Powertrains and Automotive Technology at TU Vienna, they have developed in partnership with Magna Steyr, a drive train with a gas engine for an ultralight vehicle in the A segment.
