Experimental investigation of performance characteristics of compression-ignition engine with biodiesel blends of Jatropha oil & coconut oil at fixed compression ratio

Abstract

The present research investigates raw oil (Jatropha and coconut oil Fuel), which lies in the edible and non-edible vegetable oils category. We have a set opinion to be taken as potential alternative fuels for C.I. engines and are choosing to search out their quality being employed as a future fuel. The most effective distinction between these two varieties of oils and diesel fuel is viscosity. The blends of the above oils prepared along with pure diesel. Each oil was separately blended in variable proportion (20%–50%) with pure diesel. We have experimented to monitor and analyze the performance of pure diesel fuel against various blends (B20 to B50) of Jatropha-biodiesel & Coconut-biodiesel at a fixed compression ratio i.e. eighteen. The performance limits that were under study and compared are the variation of brake specific fuel consumption & brake thermal efficiency with various loads for many fuel blends.

Experimental assessment of performance and emissions for hydrogen-diesel dual fuel operation in a low displacement compression ignition engine

“…Transport is carried out almost entirely (>99%), with internal combustion engines that most likely use liquid fuels derived from petroleum [ 18 ]. Internal combustion engines have a wide range of applications, and all their parameters must be assessed to reveal their influence on performance and greenhouse gas emissions [ 19 , 20 ]. Different technologies aim to increase the efficiency of these engines via waste heat recovery from exhaust gases.…”

Correlation between Emission and Combustion Characteristics with the Compression Ratio and Fuel Injection Timing in Tribologically Optimized Diesel Engine

“…In line with aforementioned, numerous studies dealing with examination and experimental activities aimed at evaluation of different characteristics of CI engines have been elaborated as well. For instance, the literature [46] addresses multiple performance characteristics of CI engine with raw oil (Jatropha and coconut oil) fuel mixtures at fixed CR, wherein analysis of the performance of pure diesel fuel compared to several fuel mixtures of Jatropha-biodiesel and coconut-biodiesel at a fixed compression ratio is carried out. Or, the paper [47] tests a single cylinder direct injection engine under various CR of (18, 17 and 16:1) while differing in loads.…”

Computational modeling and multi-objective optimization of engine performance of biodiesel made with castor oil

“…A very important aspect of research on biodiesel has to do with its effects on engine performance and emissions (Ghazali et al, 2015). Such researches evaluate engine performance characteristics and emission levels using such indicators as brake torque, brake power, brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), Nitrogen Oxide (NOx), PM,CO,CO2, HC, smoke density etc and compare them with pure diesel and biodiesel blends (Ude et al, 2017;Rathore et al, 2019). Investigation by Ganesan et al (2019) on engine performance of mustard oil based biodiesel showed that biodiesel can be used effectively as substitute for mineral diesel without redesigning the engine.…”
