Injection pressure plays an important role in the engine performance and emission control of internal combustion engines. Present work describes the experimental investigations carried on a four stroke single cylinder water cooled Kirloskar diesel engine with Cotton seed oil-diesel blends. Cotton seed oil is blended with diesel in varying proportions like ( C10, C20, C30 ) 10%, 20% and 30% and experiments were carried out by varying the injection pressures from 165 bar to 210 bar. The performance characteristics like brake thermal efficiency, brake specific fuel consumption and exhaust gas temperatures are investigated. Based on investigations, a comparison is drawn on engine performance with pure diesel operation and with different blends. Experimental results demonstrate that at 195 bar fuel injection pressure, the performance characteristics are observed to be better with blends when compared to the pure diesel operation. Maximum brake thermal efficiency observed is 34.01% with 30% blend at an injection pressure of 195 bar and lower specific fuel consumption observed is 0.258 kg/kw-hr with 30% blend at an injection pressure of 195bar.
