| Abstract | ||
| Alternative fuels are a fun renewable resource that can help minimize particle pollution from internal combustion engines. At a constant engine speed of 2500 rpm, a comparative numerical analysis was undertaken to analyze the impacts of four alternative fuels (ethanol, hydrogen, gasoline, and liquefied petroleum gas (LPG)) on exhaust gas emissions. Carbon monoxide, nitrogen oxide, and unburned hydrocarbons are all monitored as exhaust gases. According to this study, using fuels including ethanol and hydrogen can significantly reduce emissions. With hydrogen, the majority of hazardous contaminants in exhaust gas are significantly decreased. In comparison to gasoline, hydrogen contains relatively clean unburned hydrocarbons. Ethanol and hydrogen are clean fuels that do not contribute to increase in net emissions from engines. The findings showed that ethanol fuel emits less carbon monoxide than regular gasoline, but LPG emits more CO. Furthermore, ethanol fuel burns cleaner and produces less CO than gasoline. In comparison to LPG fuel engines, NOx emissions were greater for gasoline fuel engines. Nonetheless, ethanol-fueled engines created less NOx than gasoline-fueled engines. When working in lean conditions, the NOx emission of the hydrogen-fueled engine was about ten times lower than that of a gasoline-fueled engine. The studies also demonstrated that hydrogen fuel engines emit less HC pollution than gasoline fuel engines, but gasoline fuel engines emit more than ethanol fuel engines. | ||
