Numerical study on a natural gas-fueled engine under low temperature combustion mode

Natural gas, which is also referred to as eco-friendly fuel, being seen a potential solution challenge the decline of crude oil resources and deteriorating air quality in urban areas. This fuel has been verified emit less CO, HC, PM compared other fuels. A approach reducing NOx soot emissions while achieving low consumption temperature combustion process. In this study, internal engines were simulated under various conditions. The objective was investigate effect different operating variables on mode. To begin with, natural gas powered engine modeled using complex chemical kinetics software. outcomes simulation then experimental data, demonstrating high level agreement. Subsequently, impacts key variables, including air-fuel ratio, compression speed, analyzed cycle code. Increasing ratio improves performance, specific decreases. However, it leads significant increase until certain value. Thereafter, changes trend. Engine speed indirectly affects performance by increasing changing ignition timing. leaner ration may be used produce more power keep below value (low-temperature combustion), ensuring emissions.
