In this experimental investigation of the optimum combination feasibility of compression ratio (CR) and blend percentage were analyzed at constant speed by using Taguchi method. In this research performance parameter considered was Brake Thermal Efficiency (BTE), as maximum efficiency of engine is desirable. Carbon dioxide (CO2) and Nitrogen oxides were considered as emission output responses, as maximum CO2 emission is indication of reduction in HC and CO. The experimentation was carried out in single cylinder 4 stroke VCR CI engine at 16:1, 17:1 and 18:1 CR with 10, 20 and 30 percentage of Jojoba oil biodiesel-diesel blends at 1550 rpm speed. The contributions of each parameter and output response were evaluated by ANOVA and 3D surface plot. The investigational results reveals that at 18 CR and B10 BTE of engine was maximum where CR was the more influencing parameter, due better combustion of fuel at higher CR. Blend type was the more influencing factor for the higher CO2 discharge, because higher oxygen molecules in biodiesel. The influence of CR was more in production of NOx. At lower CR NOx emissions were found minimum.
