This paper aims at investigating the performance, emission and combustion characteristics of a diesel engine fuelled with CSPO (coconut shell pyro oil)-diesel blends as fuel. In the first phase of work CSPO was produced from fast pyrolysis of raw coconut shell at a reaction temperature of 700°C. Attempts were made to obtain homogeneous mixtures of different amounts (such as 5%, 10%, 15% and 20% by volume) of CSPO with diesel. Beyond 15% separation of the fuel was observed. Hence it was decided to use the blends of 5%, 10% and 15% of CSPO with diesel as fuels. Experiments were carried out on a single cylinder, water cooled, direct injection diesel engine using different blends of CSPO with diesel as fuel. Performance, emission and combustion parameters were obtained at different power outputs for all the tested fuels and analyzed.
