Compression ignition engines are widely used due to their lower energy consumption and enhanced combustion efficiency. In this experimental investigation, the feasibility of fuelling a single cylinder 4 stroke direct injection compression ignition engine with methyl esters of palmkernel (PME) oil along with various fractions of aluminium oxide nano particles (ANOP) were analysed. Two stage transesterification process was adopted to prepare PME. PME20 blend was formulated and fused using high speed homogenizer with varying proportions of AONP as 25 ppm, 50 ppm and 100 ppm in the presence of hexadecyl trimethyl ammonium bromide as surfactant. The experimental investigations were conducted at rated power of 3.5kW at 1500rpm. It was noticed that supplementation of AONP affected the ignition delay significantly favouring enhanced combustion efficiency. The rate of heat release and in-cylinder pressure was substantially increased with notable reduction in ignition delay. Addition of AONP showed an increase in brake thermal efficiency and exhaust gas temperature with diminution in brake specific energy consumption. The unburned hydrocarbons, carbon monoxide and smoke density decreased sharply with an upsurge in NOx. Increase in AONP concentration up-to 100 ppm with PME20 was found to give better combustion and performance characteristics.Keywords

Biodiesel derived from Stoechospermum marginatum is analysed in a CI engine to understand its feasibility to be used as fuel. In this study, Soxhlet extraction method was applied to extract the bio oil from the brown sea weed (S. Marginatum) with n-hexane as solvent. Considering the low FFA content through titration, base single stage transesterification process with methanol and NaOH at molar ratio of 8:1 is used and it yielded 84.5% of bio diesel. The test fuel is prepared with processed algae bio diesel and Di-Ethyl Ether in different blend ratios namely D80AB20, D70AB20DEE10 and D60AB20DEE20. The variation in combustion aspects are evaluated with constant concentration of algal bio diesel at 20% with variation in diesel and oxygenate concentrations. Consequential variation is observed in the combustion behaviour of CI engine on fuelling with test fuels. Comparable in-cylinder pressure is observed in bio-diesel blends and oxygenated blends. D70AB20DEEE10 exhibits superior heat release rate and pressure rise at all loads. The peak in-cylinder pressure and variation in ignition delay are also analysed in this study.Keywords

The present experimental investigation aims at improving the combustion and performance parameters by varying the injection timing. A 3.5 kW single cylinder stationary CI engine equipped with eddy current dynamometer is used in this investigation. The static injection timing is varied using spill method by an advancement and retirement of 2 CAD with respect to standard injection timing of 23 °BTDC. On comparison with the standard injection timing, the brake thermal efficiency, cylinder pressure, rate of heat release, mean gas temperature and rate of pressure rise are found to increase along with a significant decrease in brake specific fuel consumption for an advanced injection timing of 21 °BTDC. Negative improvement is observed with respect to retarded injection timing of 25 °BTDC. Optimum parameters for enhanced engine performance is found to be 21°BTDC injection timing with a 200 bar injection pressure at rated speed.Keywords
