Experimental Investigation on Algae Biodiesel in a Di Diesel Engine

Abstract

newlineDue to the current situation of high growth rate of automobile requirement is high and economically increased fuel prices, in this regard to overcome this criteria biodiesel are proposed as an alternative sources. Here in this research work, analyzing of various non edible oil are used as alternative fuels i.e. algae, jatropha, mahua, pongamia and neem oils. Mainly well grown algae (Chlorophyta) oil is used as alternative sources for this research work is collected and tested. The raw from the algae is converted in oil using transesterification process to reduce the oil viscosity (24.5 mm2/s at 40 °C). Then various blend of algae oil i.e. A 20, A 40, A 60, A 80, A 100 is blended with diesel D 80, D 60, D 40, D 20 and D 00 by capacitytric basics. newlineThe first part of the research work is to optimize the most effective blend among the proposed ratios, select one best blend with gives high performance by compare to other blend ratios.by the investigational results show that A20 blend has high performance then A40,A60,A80 andA100.The second part of the research is to analyzing the various test under three different parameter i.e. injection pressure (180bar, 200bar,220bar and 240bar),injection timing (15.5:1,16.5:1,17.5:1 and 18.5:1 )and compression ratio of 24o BDTC , 26oBDTC and 28o BDTC and 30oBDTC. newlineInvestigational testing on The Kirloskar engine a single cylinder, water cooled, four stroke direct injection compression ignition engine with a displacement capacity of 661 cc, compression ratio of 16.5:1, developing 6.02 kW at 1800 rpm. By the test result of A20 algae blend under different parameters as mention above, Possessions of engine speed, engine load output, injection timing of the algae biofuel and engine compression ratio on the engine output torque, combustion sound maximum pressure and newlineiv newlinemaximum heat release rate. Due the similarity in the properties of diesel and algae oil engine runs successfully and smoothly. newlineThe algae A20 blend at 200bar pressure gives high brake thermal efficiency and reduces in HC and CO emission lightly increased in Nox emission compared to 180bar, 220 bar and 240 bar pressure. As the speed increases, due to the rise in temperature and pressure, air-fuel blend formation is better, which increased in combustion efficiency and thermal efficiency. The algae A20 blend at 16.5:1 compression ratio gives high brake thermal efficiency and reduces in HC and CO emission lightly increased in Nox emission compared to 15.5:1, 17.5:1 and 19.5:1 compression ratio parameters. newlineBy this research conclude that A20 blend has high performance at 200bar pressure, 16.5:1 compression ratio and 26o BDTC compared to other parameters and reduced emission when compared to diesel fuel. newline
