A signifi cant contribution to reach the goals of Paris´ climate agreement and to become greenhouse-gas-free by 2050 can be provided by utilizing alternative fuels in internal combustion engines. More precisely, the conversion of CO2 neutral wood gas from air gasifi cation in stationary internal combustion engines enables sustainable power generation. However,due to its variable composition, especially H2 and H2O content, as well as low heating value, the engine operation with wood gas is challenging. As a part of the research projects, the wood gas production process and its utilization in the internal combustion engine of a wood gas Combined Heat and Power plant (Pel<100kWel) have been analyzed. In addition, the engine operation with various wood gas compositions has been investigated on the adaptive engine test bench with a gas mixer at TU Wien. Based on these investigations, a joint experimental approach to optimize the wood gasification process and the engine operation is defi ned. Regardless of the adverse properties of wood gas for engine operation, high effi ciency and low emissions can be realized with selective optimization measures of the engine and combustion process.
