| 抄録（英） | In recent years, the carbon neutrality movement has become more evident in the automotive industry, and internal combustion engines that use fossil fuels are becoming unsustainable. Hydrogen engines do not emit CO2 during operation. If the working gas in a hydrogen engine is replaced by argon and oxygen instead of air (argon is circulated by removing the produced water), the thermal efficiency can also be dramatically improved. However, when the high adiabatic compression temperature of argon is added to the inherent knocking problems of hydrogen engines, the knocking problem becomes even more pronounced, and no effective solution to avoid knocking has been found to date. In this study, the effects of argon, oxygen, and hydrogen concentrations on combustion and power, respectively, were investigated to determine the effects of working gas composition on combustion and knocking, and the control effects of oxygen rich or hydrogen rich on knocking was investigated. In this study, the purpose was to investigate the effects of working gas composition on combustion and knocking. The effects of argon, oxygen, and hydrogen concentrations on combustion and power were investigated, and the control effects of oxygen rich or hydrogen rich on knocking were discussed. Furthermore, by applying this control method, stable operation without knocking was achieved even at a compression ratio of 8.70 with an equivalent ratio of 0.22 for oxygen rich, and indicate effective pressure and indicate thermal efficiency reached 0.575 MPa and 58.1%, respectively. 翻訳 |
