  • Abstract:
  • Now-a-days the usage of conventional fuels such as petrol and diesel are increased and get depleted gradually and there is a need for suitable alternative fuels for IC engines. The most suitable among the available alternative fuels are in the form of alcohols and vegetable oils which are easily available and are renewable in nature besides being cost effective. The process used to make vegetable oils suitable for use in CI engines is to convert it in to biodiesel using Transesterification process. The Crude Hibiscus oil is converted to Hibiscus Oil Ethyl Esters (HOEE) by transesterification process by using ethyl alcohol. The biodiesel fuel properties such as viscosity and specific gravity of Hibiscus Oil Ethyl Esters are obtained. Experimental investigation is conducted on the single cylinder water cooled diesel engine with constant speeds with various loads using diesel base line data. In the second stage the experimental investigation has been carried out on same engine using Hibiscus Oil Ethyl Esters with different proportions H5, H15, H25, and H35 blends. The performance and emission parameters obtained by HOEE are compared with diesel and H15 is the optimum blend obtained. After finding optimum blend, the tests were conducted on the same engine with addition of 1-Hexanol at 5%, 10% and 15% on volume basis and evaluate its effects on diesel engine characteristics. The main purpose of fuel additives is to improve the combustion process and reductions of exhaust emissions. Finally, the experimental outcomes are analyzed with the diesel.
