Abstract:
An experimental investigation was conducted in this study to assess the effects of adding different levels of Graphene Oxide (GO) 25, 50, and 75 ppm on engine parameters in an HCCI engine operating with a blend of 20, 40, and 60% Algae Methyl Ester (AME). The quality of PG is critical for running power generation engines at the desired performance level. A mathematical analysis was performed on a Homogeneous-Charge Compression Ignition (HCCI) diesel engine for CV of PG from 10, 20, and 30 MJ/Nm3 of coconut shell, which was included in this study. Following that, an optimization using Response Surface Methodology (RSM) was performed to establish the optimal working conditions at various engine loads. According to the results of the experiments, GO additives are an excellent addition to diesel-AME blends to improve performance as well as decrease emissions. The model predicted the best result with predicted and actual graphs, with the lower BTE being 20.25%. The higher BTE is 26%, the lower BSFC is 1.69 kg/kWh, the higher BSFC is 2.46 kg/kWh, and the lower CO content of the exhaust is 0.04 vol%. The higher CO content is 0.22 vol%, the lower HC emission is 18.82 ppm, the higher HC emission is 30.3 ppm, and the lower NoX emission is 201 ppm. In contrast, the more significant NoX emission is 301 ppm; lower smoke emissions are reported at 21.01%, whereas higher smoke emissions are reported at 35.4%. According to the study’s findings, it is possible to conclude that the RSM model may effectively model an HCCI diesel engine, saving time and money.
