Impact of non-edible biodiesel (Juliflora oil seed) on CI engine – Combustion, performance and emission features

Abstract

Diesel fuel is a major contributor towards the unanimity of world economy growth. The sustainable growth of economy affects slightly by diesel fuel emissions and this small obstacle leading in further carbon footprint. In the context, bio-diesel is an emerging diesel-substitute forefront for combustion engines as their behavior similar to that of diesel fuel. The current study looks into the performance, burning efficiency, and emissions of B100% P.Juliflora biodiesel blends in a CI engines at various load conditions. The engine trials were conducted on a 4-Stroke Solitary-Cylinder engine diesel, with 17.5 as a Compression Ratio, at constant speed of 1500 rpm with water cooled engine. The biodiesel is derived from one of the best and most cost effective transesterification technique. Their fatty acid composition were estimated and derived physical and chemical properties were studied. It is observed that by using P.Juliflora seed oil as a biodiesel fuel gives positive impact on BTE and better emission controls due to their differences in saturation and unsaturation levels of FFA compositions. The experimental test results revealed the following findings: it is evident that P.Juliflora biodiesel shows closer value of Brake thermal performance (BTE) compaed to diesel fuel at partial and marginal load with little increase in BSFC values. The BSFC values for blends B100 is (0.34 kg/KWh) was higher than diesel (0.25 kg/KWh) at full load strokes. Furthermore, low emissions were recorded for HC, Smoke, CO, CO2 with slight increase in NOx emissions. The diesel engine experimental standards and characteristics/properties of Juliflora oil findings were presented in tables and graphically.
