Andre Tänzler demonstrates fundamental thermodynamic relationships and the operational limits of the dual-fuel combustion process. He investigates the potential for reducing greenhouse gas emissions by utilizing high proportions of natural gas. In this context, the conflict between reduced CO2 emissions and increased methane emissions plays a crucial role in the overall assessment of greenhouse potential. To further reduce emissions, the author develops an alternative piston material with a reduced crown height, identifying different diesel injection patterns to generate homogeneous diesel combustion on a lean background mixture of natural gas and air as a key parameter.
