The increasing price of conventional diesel fuel, its deficiency, and the injurious outcome of combustion produced contaminants seem to make different sources more fascinating. Leucas zeylanica plant is noncomestible in nature and available abundantly. Leucas zeylanica methyl ester is renewable and least polluting fuel, which can supplement fossil fuels with unmodified engine condition. The existing experimentation assesses the performance and emission analysis by using various blends of leucas zeylanica methyl ester, diesel, and diesel additives like 2-ethylhexyl nitrate. This experimental investigation gives less engine emission and better performance as compared with mineral diesel. In the radical portion of this investigation, fuzzy-based Taguchi optimization for predicting the optimum input blends results in the optimum combination of performance and emissions parameter.

In the present work, the combustion, performance and emission characteristics of sunflower oil, sunflower methyl ester and its blends were studied and compared with diesel by employing them as fuel in a single cylinder, direct injection, 4.4 KW, air cooled diesel engine. Emission measurements were carried out using five-gas exhaust gas analyzer and smoke meter. The performance characteristics of Sunflower oil, Sunflower methyl ester and its blends were comparable with those of diesel. The components of exhaust such as HC, CO, NOx and soot concentration of the fuels were measured and presented as a function of load and it was observed that the blends had similar performance and emission characteristics as those of diesel. NOx emissions of sunflower oil methyl ester were slightly higher than that of diesel but that of sunflower oil was slightly lower than that of diesel. With respect to the combustion characteristics it was found that the biofuels have lower ignition delay than diesel. The heat release rate was very high for diesel than for the biofuel.

In the present investigation, tests were carried out to determine engine performance, combustion and emissions of a naturally aspirated direct injection diesel engine fueled with diesel and Jatropha Methyl ester and their blends (JME10, JME20 and JME30). Comparison of performance and emission was done for different values of compression ratio, injection pressure and injection timing to find best possible combination for operating engine with JME. It is found that the combined compression ratio of 19:1, injection pressure of 240 bar and injection timing of 27?bTDC increases the BTHE and reduces BSFC while having lower emissions.From the investigation, it is concluded that the both performance and emissions can considerably improved for Methyl ester of jatropha oil blended fuel JME20 compared to diesel.

Current demands on renewable alternative fuel, biodiesel claims considerable significance. Biodiesel can be produced from any type of vegetable oils but yielding is determined by its free fatty acid (FFA) content. The alkaline-catalyzed esterification is not suitable for the unrefined vegetable oil which has high acid content. Hence, two-step esterification process is used to derive the kapok methyl ester due to its high FFA value. The biodiesel production in the two step process consists of acid-catalyzed pretreatment followed by an alkaline-catalyzed transesterificatin. In this study, experimental investigations are carried out in compression ignition engine to analyze the properties, performance and emissions characteristics of different blends of kapok methyl ester and compared with diesel. The exhaust gas temperature and specific fuel consumption are increased with increase of load and amount of biodiesel. The CO2 emission is slightly higher and NOx emission is about 22 percentage higher than that of the diesel at all the loads of engine. However, lower biodiesel blends showed reasonable efficiencies, lower value of smoke, CO and HC emissions.

In the present scenario when the world is facing severe problem related to continuous decrease in the level of fossil fuels and increasing level of green house gases due to their uses in industries and automobiles, there is a high demand from all technologists and environmentalists to find and develop some alternative fuel especially manufactured from biomass like chlorella algae due to its presence in abundance. The mentioned algae is readily available and is being used as a dietary source in many countries especially in Japan due to its rich protein lipids and starch content and highly suitable for extraction of oil that can be used as an alternative to the existing fossil fuel diesel. The blend of B20 chlorella algae methyl ester or biodiesel is tested for its suitability with respect to its combustion performance and emissions characteristics in a variable compression ratio engine at 180 bar, 200 bar and 220 bar injection pressures. The performance data obtained are compared and analyzed for optimum performance with reference to mechanical, combustion properties and emissions of exhaust gases and a comparison is made with the properties obtained for pure diesel in similar conditions

In recent years, industries have been investing to develop a potential alternative fuel to substitute the depleting fossil fuels which emit noxious emissions. Present work investigated the effect of ferrous ferric oxide nano-additive on performance and emission parameters of compression ignition engine fuelled with chicken fat methyl ester blends. The nano-additive was included with various methyl ester blends at different ppm of 50, 100, and 150 through the ultrasonication process. Probe sonicator was utilized for nano-fuel preparation to inhibit the formation of agglomeration of nanoparticles in base fuel. Experimental results revealed that the addition of 100 ppm dosage of ferrous ferric oxide nanoparticles in blends significantly improves the combustion performance and substantially decrease the pernicious emissions of the engine. It is also found from an experimental results analysis that brake thermal efficiency (BTE) improved by 4.84%, a reduction in brake specific fuel consumption (BSFC) by 10.44%, brake specific energy consumption (BSEC) by 9.44%, exhaust gas temperature (EGT) by 19.47%, carbon monoxides (CO) by 53.22%, unburned hydrocarbon (UHC) by 21.73%, nitrogen oxides (NOx) by 15.39%, and smoke by 14.73% for the nano-fuel B20FFO100 blend. By seeing of analysis, it is concluded that the doping of ferrous ferric oxide nano-additive in chicken fat methyl ester blends shows an overall development in engine characteristics.

Bio-additive is biodegradable and produces less air pollution thus significant for replacing the limited fossil fuels and reducing threats to the environment from exhaust emissions and global warming. Instead, the bio-additives can remarkably improve the fuel economy SI engine while operating on all kinds of fuel. Some of the bio-additive has the ability to reduce the total CO2 emission from internal petrol engine. This review paper focuses to determine a new approach in potential of bio-additives blends operating with bio-petrol on performance and emissions of spark ignition engine. It is shown that the variant in bio-additives blending ratio and engine operational condition are reduced engine-out emissions and increased efficiency. It seems that the bio-additives can increase the maximum cylinder combustion pressure, improve exhaust emissions and largely reduce the friction coefficient. The review concludes that the additives usage in bio-petrol is inseparable for the better engine performance and emission control and further research is needed to develop bio-petrol specific additives.

Moringa Oil

World at present is confronted with the twin crisis of fossil fuel depletion and environmental pollution. Rapid escalation in prices and hydrocarbon resources depletion has led us to look for alternative fuels, which can satisfy ever increasing demands of energy as well as protect the environment from noxious pollutants. In this direction an attempt has been made to study a biodiesel, namely Moringa Oil Methyl Esters [MOME]. All the experiments were carried out on a 4.4 kW naturally aspirated stationary direct injection diesel engine coupled with a dynamometer to determine the engine performance and emission analysis for MOME. It was observed that there was a reduction in HC, CO and PM emissions along with a substantial increase in NOx. MOME and its blends had slightly lower thermal efficiency than diesel oil.
