“…The CO emissions are produced when the droplets from the injector are too large or insufficient turbulence is created in the combustion chamber as explained by Resitoglu et al (2014). The other reason attributed to the secondary atomization phenomenon in the combustion chamber is the uniform dispersion of nanoparticles present in the biodiesel-diesel fuel blend which in turn reacts with the available air to undergo complete combustion in the engine cylinder as explained by Basha and Anand (2012).…”

An experimental investigation was carried out to study the performance, emissions and combustion characteristics of a compression ignition (CI) engine fuelled with waste chicken fat biodiesel with alumina nanoparticles as an additive. The disposal of waste chicken creates environmental pollution, hence it is decided to extract oil from the waste chicken fat and produce biodiesel through transesterification process. As the chicken fat contains 13.6 % free fatty acid (FFA), a pre-treatment process was carried out using Ferric sulphate as a catalyst in order to reduce the FFA content less than 1 % to prevent soap formation during the process. Potassium hydroxide was used as catalysts for the effective conversion of triglycerides of waste chicken fat into methyl ester. Various diesel-biodiesel-alumina blends were prepared by varying the biodiesel proportions of 20 and 40 % by volume and 25 and 50 ppm of alumina nanoparticles to study its operating characteristics on a computerized single cylinder, constant speed CI engine. Aluminium oxide (Al 2 O 3 ) nanoparticles were used as fuel born catalyst in order to enhance the combustion characteristics and reduce the harmful emissions. The engine test results showed less improvement in brake thermal efficiency and significant reduction on the hydrocarbons and carbon monoxide emissions. However, higher nitrogen oxide emissions were recorded due to the increase in combustion temperature as the nanoparticles enhanced the surface area to volume ratio which improves the thermal conductivity of the fuel blend resulted in improved combustion. Smoke reduction of 52.8 % was observed in B40 fuel blend with 50 ppm alumina nanoparticles under full load conditions.

“…More quantity of fuel is burnt in the premixed combustion phase [5,18,20,26,29].It was observed that heat release rate and cylinder gas pressure characteristics were higher for the alumina oxide nanoparticle blended fuels (B20+ 20 NAO, B20+ 30 NAO and B20+ 40 NAO) compared to biodiesel blend B20. This is could be due to accelerated combustion due to the shortened ignition delay, improved atomization, rapid evaporation of fuel, the degree of fuel mixing and uniform burning could have improved [11,26,37,38]. Increase in the ignition delay period had bad effects in fuel atomization and evaporation.…”

“…Basha and Anand [10] blended Carbon Nanotube at 25, 50 and 100 ppm in Jatropha methyl ester emulsion (5% of water and 2% of surfactants (by volume)) and found drastic percentage reduction of NO by 29 % and smoke opacity by 28 % in a single cylinder, four-stroke, direct injection diesel engine. An experimental investigation was carried out with alumina nanoparticle, blended at 25 and 50 ppm in water diesel emulsion and observed drastic percentage reduction of NO by 27 %, smoke opacity by 40 % with marginal reduction of HC and CO emission [11]. Amit and Sudhir Kumar [12] carried out an experimental analysis to evaluate the impact on the performance of direct compression ignition engine by adding cobalt oxide and iron oxide nano particle in jatropha biodiesel in mixed proportion of 10, 20, 30, 40, 50 and 60 parts per million.…”

In the present energy scenario of increased energy demand, rapid depletion of petroleum resources and increased environmental problems, the search for new renewable and alternative fuels have gained momentum. This study represents an experimental investigation to examine the effect of nano additives on single cylinder DI diesel engine performance at variable operating conditions. In this work alumina nanoparticles having average size of ~10 nm were dispersed in a mixture of jatropha methyl ester and conventional diesel fuel (20% jatropha biodiesel and 80% diesel fuel) at proportion of 20, 30 and 40 parts per million. The obtained results were compared with neat diesel and B20 as base fuels. It is found that, the appropriate nanoadditives dose corresponding to optimal engine performance is about 40 ppm of alumina nanoparticle. At this dose, the overall BSFC is reduced by about 12.5%, engine thermal efficiency is increased up to 12%, and exhaust gas temperature is reduced by 13%. Along with percentage reduction of smoke opacity by 20 %, unburned hydrocarbon by 10 %, carbon monoxide by 29 % and nitrogen oxides by 13% compared with the corresponding values obtained when only a blended fuel of 20% biodiesel is used. Such type of biofuel based Nano fluids having improved performance characteristics can be utilized directly as an alternate fuel for diesel engines.

Energy demands for petroleum products are increasing since its rate of fuel consumption is increasing. The whole world suffers from shortage of petroleum products. Therefore it is necessary to find alternative fuels of fuel consumption reduction and harmful exhaust emission. Biodiesel was produced from jatropha oil by esterification followed by transesterification process. The aim of this paper is to measure performance and exhaust emissions of a diesel engine using jatropha biodiesel blends by adding appropriate concentrations of carbon nano additives. Carbon nano additives were mixed with biodiesel blends at the rate of 25mg/l, 50 mg/l and 100 mg/l as 25, 50 and 100 ppm. An experimental investigation was carried out on a single cylinder diesel engine at different engine loads using Jatropha biodiesel and nano additives. Measured physical and chemical properties of jatropha biodiesel (B20) were found to be within ASTM standards. Tests showed a considerable enhancement in engine performance and exhaust emission compared to biodiesel blends without nano additives. Experimental test results indicated that adding carbon nano particles to biodiesel fuel decreased about 5.71% in brake specific fuel consumption and 13.34% increased in brake thermal efficiency compared to pure diesel fuel. Combustion of jatropha biodiesel (B20C50) resulted in decreases in CO, NO x , and smoke emissions by about 36.36, 57.14 and 43.66%, respectively as compared to diesel oil. Jatropha biodiesel blend with CNTs at concentration of 50 ppm is environmentally friendly and achieved better engine performance compared to other fuels. Thus it is recommended to use jatropha biodiesel with carbon nano-additives as an alternative fuel in diesel engines.
