Various compression ratio strategies on introducing TiO2 in diesel - Palm oil blends in compression engine against diesel fuel for enhanced engine brake horsepower.

This study focuses on developing fuel to enhance base horsepower with nano additives, palm oil and a novel diesel blend compared with plain diesel. Materials and Methods: Palm oil which was transesterified, is then blended with diesel at a ratio(20%), was then added with TiO2 nanoparticles(50 ppm) by ultrasonic sonicator and was compared with diesel. Experimentation was carried out with a Kirloskar single-cylinder diesel engine with Bore - 87.50mm diameter and stroke length-110mm onboard stationary engine coupled with eddy current dynamometer with conventional settings. The sample size was 40 and the sample size was calculated using the G power calculator with 80%. Results: Based on the experimental trials, the base horsepower for neat diesel is 1.31 kW, and for the blend(P20D80) with compression ratio 17.5 was 1.29 kW and for 19 was 1.27 kW. Within the limits of this study, the base horsepower acquired in this research for the prepared biodiesel P20D80 of the same compression ratio was 1.52% lower and 3.05% lower with a compression ratio of 19 compared with the plain diesel with a compression ratio of 17.
