The current work investigated the characteristics of a diesel engine working with the ternary biodiesel blend having equal amounts of Jatropha, Karanja, and Cottonseed oils. The biodiesel constitutes 6.67% of each constituent oils and 80% diesel by volume. The impact of compression ratio on various characteristic parameters of a single cylinder diesel engine have been experimentally investigated to achieve enhanced performance and emission parameters. The compression ratio was varied from 15 to 18 and the results for the corresponding parameters were compared with the same parameters of the engine running with pure diesel at nominal compression ratio of 16. The brake thermal efficiency increased by 2.3% while the fuel consumption for unit power output reduced by 0.06 kg/kWh for the biodiesel at compression ratio 18. The hydrocarbon emission at compression ratio 18 with ternary blend biodiesel reduced by 37% than diesel while the carbon monoxide decreased by 42%. The oxides of nitrogen increased for biodiesel compared to pure diesel and it further increased with compression ratio due to better combustion of fuel. Thus, the biodiesel containing of 20% methyl esters of jatropha, karanja and cottonseed oil can be suitably adopted as an alternate fuel for automotive engines at higher compression ratio.
