Methodologies for conducting experimental studies related to the application of gaseous fuels in internal combustion engines

Abstract The publication presents the methodologies developed by the authors for conducting experimental studies in the field of gaseous fuels used in internal combustion engines (ICEs). These methodologies are applicable to engine operation under test bench conditions. They cover both engines with compression ignition and those with spark ignition of the fuel mixture. For spark ignition engines, the methodologies consider both their operation solely on gaseous fuel and in dual-fuel mode with gasoline. The implementation of the methodologies is illustrated through various examples related to ICE operation with gaseous fuels.
