The Effect of Injection Timing on Combustion, Performance and Emission Parameters with AOME Blends as a Fuel for Compression Ignition Engine

Authors : V. Hariram and G. Mohan Kumar

Abstract: An experimental investigation has been carried out to analyze the effect of injection timing on performance, combustion and emission parameters of a single cylinder compression ignition engine when algal oil methyl ester and its blends are used as a fuel in the ratio of 5, 10 and 20% without any modification in the existing experimental setup. The algal oil methyl ester is derived from Spirulina sp. and its properties are validated against ASTM standards and found within limits. The present study is focused on experimentally investigating the influence of injection timing with advancement, rated and retarded crank angle and load on combustion pressure, Rate of Heat Release (ROHR), Brake Specific Fuel Consumption (BSFC), Brake Thermal Efficiency (BTE), Unburned Hydrocarbon (UBHC), Carbon monoxide (CO), Oxides of Nitrogen (NOx) and smoke. It has been observed that BSFC, UBHC, CO and smoke is reduced with advancement of injection timing of 5° from the original setting and combustion pressure, ROHR, BMEP and NOx are increased. The retardment of injecting timing by 5° created a negative improvement of the above parameter. The best injection timing was found to be 340 crank angle degree with optimum performance, better combustion characteristics and minimal emission.
