Combined Effect of Compression Ratio and Fuel Injection Pressure on CI Engine Equipped with CRDi System Using Prosopis juliflora Methyl Ester/Diesel Blends

The exhaustion of worldwide oil reserves has created an incipient need to find hopeful alternative fuels for the future. Substantial research been done in this direction, and all studies by researchers have provided results that proved growing potential biofuel as a popular CI engine. current investigation explores derived from wasteland tree Prosopis juliflora (Karuvalam seeds). Experimentation was using monocylinder 4-stroke water-cooled six holes CRDi engine with electrical loading. experiment conducted at three proportions (10%, 20%, 30% volume basis) Oil Methyl Ester (PJOME) diesel 3 parametric CRs (16, 17.5, 19) along different fuel injection pressure (FIP) (400, 500, 600 bar). impact CR FIP on utilization BTE, cylinder pressure, net heat release, exhaust particulates scrutinized characterized. test demonstrated increasing compression ratio 16 19 enhanced in-cylinder release (NHR), BTE (PJOME/Diesel) combinations. With augmentation 19, carbon monoxide unburnt hydrocarbon discharge diminished, but nitrogen oxide discharges augmented. also had pressures in-cylinder, NHR, brake thermal efficiency, reducing emissions smoke, CO, UBHC. shows use B20 CR16 bar combination improved 33.21%, BSFC 0.25 kg/kw-hr, maximum reach 69.28 bar, 79.14 J/deg, such UHC 55 ppm, CO 0.25%, smoke 34.33%, NOx 2401 ppm. Finally, were slightly higher, UHC, values diminutive compared other blends.
