Impact of Oxygenated Persea Americana Biodiesel at Varied Compression Ratio on the Emission and Performance Parameters of a CI Engine

One of the biodiesel forms considered for research in the recent past is mixture of Avocado oil with diesel because the waste produced by avocado fruit is very huge which is not limited to the peel and stone. This paper deals with the comparison of performance and emissions of mixtures with different percentages of diesel, avocado oil and diethyl ether (DEE). The biodiesel is prepared through the process of transesterification process under acid-base catalyst. The performance characteristics considered for comparison are Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE). The emissions considered are smoke, Carbon monoxide (CO), Nitrogen Oxides (NOx), Carbon dioxide (CO2) and Unburned Hydrocarbons (UBHC). The results show that mixing avocado biodiesel in the prescience of Di-ethyl ether with diesel proved to be encouraging. Different compression ratios, namely, 17%, 17.5% and 18% were assessed and the results are reported. © 2023. Carbon Magics Ltd.
