Summary: Low-temperature combustion has the potential to reduce NOx and PM emissions, but faces challenges of high HC and CO emissions. The use of oxygenated fuels like biodiesel in PCI combustion can help suppress CO and HC emissions while maintaining low levels of NOx and PM emissions. However, biodiesel's lower heating value leads to higher fuel consumption compared to diesel, and early injection timing in PCI combustion results in higher CO and HC emissions.

Summary: The main purpose of this study is to analyze the effects of oxy hydrogen (HHO) along with the Moringa oleifera biodiesel blend on engine performance, combustion, and emission characteristics. The results show that adding HHO gas to the blend can reduce fuel consumption and the concentration of CO, HC, and CO2 emissions, but does not reduce the formation of NO. However, adding HHO to the biodiesel can significantly reduce the average NOx.
