“…Similarly, variations in emissions from biodiesels using different feedstocks have been reported in many other recent studies [26][27][28]. Monyem and Gerpen [15] found that oxidized biodiesel can significantly reduce emissions while investigating the effect of biodiesel oxidation on diesel engine emissions.…”

“…PM, HC and CO emission is independent of the feedstock of the biodiesel. Aromatic pollutants in biodiesel generally have lower emission compared to AGO, although emissions of benzene and several other VOCs sometimes increase as have been reported by Banapurmath et al [28], Ozsezen et al [27], Sahoo et al [26], Raheman and Ghadge [22] and Ayadin and Bayindir [16]. The specific fuel consumption (SFC), specific fuel consumption rate (SFCR), brake thermal efficiency (BTE) are quite lower in AGO than in the algal biodiesel and blends by about 5% -31% as the speed increases.…”

Abstract. Micro-algae are a large and diverse group of simple typically autotrophic organisms which have the potential to produce greater amounts of non-polar lipids and biomass than most terrestrial biodiesel feedstocks. Having emerged as one of the most promising sources for biodiesel production, they are gaining research interests in the current energy scenario due to their phenomenal growth potential (< 21 days log phase) in addition to relatively high lipids production which are also excellent source of biodiesel. In this study, engine performance and emission profile was performed using biodiesel fuels and blends from micro-algal technology in a compression ignition engine. The technology of micro-algae involved open pond cultivation and the use of photo-bioreactor model BF-115 Bioflo/celli Gen made in the US of 14 litre capacity (200 Lux light intensity) and flowrate of 2.5L/min. The micro-algal species used were Chlorella vulgaris Scenedesmus obliquus, Senechococus spp and Duneliella spp. The biodiesel produced were blended with conventional diesel (AGO) at different proportions. The performance parameters evaluated include: engine power, torque, brake specific fuel consumption (BSFC), smoke opacity, thermal gravimetry, thermal efficiency, exhaust gas temperatures and lubricity while the varying effects of emission pollutants during combustion were also studied. Results showed that viscosity, density and lubricity have significant effects on engine output power and torque than when throttled with AGO which was used as control. Combustion efficiency and emission profile were better than the AGO due to the oxygenated nature of the micro-algal biodiesel which brought about complete combustion. A striking deduction arrived is that oxygen content of the algal biodiesel had direct influence on smoke opacity and emissions in the engine and also thermo-gravimetrically stable for other thermal applications. The engine tests (BSFC, BTE, ThE, MechE, EGT) and overall emissions (CO 2 , CO, VOCs, HC, SOx, NOx) were within acceptable limits and comparable with AGO. The implication of the study is that Micro-algal technology is feasible and can revolutionize development in biodiesel industry.

Müllerová D., Landis M., Schiess I., Jablonický J., Prístavka M., 2011. Operating parameters and emission evaluation of tractors running on diesel oil and biofuel. Res. Agr. Eng., 57 (Special Issue): S35-S42.This work is aimed at the evaluation of the operating parameters and emission of two tractors: Hürlimann H-488 DT and Hürlimann XB Max 100. The measurements were done on a test bench in the laboratory of the Agroscope Reckenholz-Tänikon Research Station ART, Ettenhausen, Switzerland during February 2010. The goal of this paper was to evaluate the operating parameters of the two models of tractors by using classical diesel oil and biofuel, as well as to evaluate the emission (greenhouse gases, dangerous exhaust gases and carcinogens), to make statistical analysis of the results and the conclusion about the samples used and the impact on engine parameters, environment and human health. From the results achieved, it is possible to state the following facts. In each way, the emissions of rape seed methylester (RME) and diesel are equivalent. The values of CO and HC and also particles are lower for RME. But NO x values are lower for diesel oil. It is liquid that the newer engine of Hürlimann XB Max 100 decreases emission of CO, HC and NO x significantly.

“…Furthermore, such nanomaterials have high surface to volume ratio and hence larger surface contact area during the rapid oxidation process. In addition, due to size dependent properties they can have the potential to release higher energy and hence can improve the fuel characteristics of the diesel engines [2][3][4][5][6]. D.

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.
