Abstract: The objective of the present study is to scrutinize the influence of a binary blend of diesel–safflower oil biodiesel and ternary blends of diesel–biodiesel–pentanol on performance, emission and combustion characteristics of a diesel power generator. The test fuels were prepared on volume basis by splash blending and named as follows: B20, B20P5, B20P10, B20P15, and B20P20. The tests were carried out on a single-cylinder, four-stroke, naturally aspirated, and direct-injection diesel engine at four engine loads with a constant engine speed of 3000 rpm. According to the results, ternary blends vaguely reduced BTE while increased BSFC up to 13.90% as compared to diesel. In addition, an increase in pentanol concentration has a considerable effect on the decrease in NOX emissions. It is noted that the addition of pentanol to diesel–biodiesel blend caused to lower emissions (CO, HC, and smoke), whereas CO2 emission increased noticeably thanks to the more complete combustion due to the excess oxygen content. Reviewing combustion analysis results, pentanol addition led to decrease heat release rate and lower ignition delay up to 15% blend ratio compared to diesel. Based on the present study, pentanol can be evaluated as a promising type of higher alcohol for the compression ignition engines in the near future.

Abstract: The present investigation uses a blend of Nigella sativa biodiesel, diesel, n-butanol, and graphene oxide nanoparticles to enhance the performance, combustion and symmetric characteristics and to reduce the emissions from the diesel engine of a modified common rail direct injection (CRDI). A symmetric toroidal-type combustion chamber and a six-hole solenoid fuel injector were used in the current investigation. The research aimed to study the effect of two fuel additives, n-butanol and synthesized asymmetric graphene oxide nanoparticles, in improving the fuel properties of Nigella sativa biodiesel (NSME25). The concentration of n-butanol (10%) was kept constant, and asymmetric graphene oxide nano-additive and sodium dodecyl benzene sulphonate (SDBS) surfactant were added to n-butanol and NSME25 in the form of nanofluid in varying proportions. The nanofluids were prepared using a probe sonication process to prevent nanoparticles from agglomerating in the base fluid. The process was repeated for biodiesel, n-butanol and nanofluid, and four different stable and symmetric nanofuel mixtures were prepared by varying the graphene oxide (30, 60, 90 and 120 ppm). The nanofuel blend NSME25B10GO90 displayed an enhancement in the brake thermal efficiency (BTE) and a reduction in brake-specific fuel consumption (BSFC) at maximum load due to high catalytic activity and the enhanced microexplosion phenomenon developed by graphene oxide nanoparticles. The heat release rate (HRR), in-cylinder temperature increased, while exhaust gas temperature (EGT) decreased. Smoke, hydrocarbon (HC), carbon monoxide (CO2) and carbon monoxide (CO) emissions also fell, in a trade-off with marginally increased NOx, for all nanofuel blends, compared with Nigella sativa biodiesel. The results obtained indicates that 90 ppm of graphene oxide nanoparticles and 10% n-butanol in Nigella sativa biodiesel are comparable with diesel fuel.

Abstract: Nowadays, energy consumption is progressively boosting in all sectors because of the rising in population and enhancing lifestyle. The dependency over fossil-based fuels has been increasing due to the ever-growing need for energy. The declining characterization of such energy sources and the increment nature of energy demand have led to vital apprehensions of energy regarding future energy safety. Keeping this in mind, the usage of alternative fuels such as biodiesel can be one of the possible solutions in order to accomplish the future energy demand. In this context, the biodiesel production is an attractive way for researchers. Biodiesel is non-toxic, biodegradable and renewable fuel that can be produced from vegetable oils, animal fats and also their wastes by applying different techniques. Contrary to the advantages, the biggest disadvantage of biodiesel is that costs are largely dependent on the feedstock. Although it has the nature of the food, safflower (Carthamus tinctorius L.) can be utilized as a feedstock for biodiesel production because its oil consumption is limited and it can be grown in arid and dry areas all over the world. This review paper has presented a detailed overview of safflower plant, the physicochemical properties of safflower oil and its biodiesel, the performance, emission and combustion characteristics of the safflower oil biodiesel when used in a diesel engine. The findings of the present work revealed that biodiesel production from safflower oil is possible and the observations from the literature resulted in comparable fuel properties, engine performance and emission parameters with those of diesel.
