K.Vijayaraj a* , A. P. Sathiyagnanam b a* Research Scholar, Department of Mechanical Engineering, Annamalai University, Tamilnadu, India. b Assistant Professor, Department of Mechanical Engineering, Annamalai University, Tamilnadu, India. Abstract-- Petroleum based fuels worldwide have not only resulted in the rapid depletion of conventional energy sources, but have also caused severe air pollution. The search for an alternate fuel has led to many findings due to which a wide variety of alternative fuels are available at our disposal now. The existing studies have revealed the use of vegetable oils for engines as an alternative for diesel fuel. However, there is a limitation in using straight vegetable oils in diesel engines due to their high viscosity and low volatility. In the present work, neat mango seed oil is converted into their respective methyl ester through transesterification process. Experiments are conducted using various blends of methyl ester of mango seed oil with diesel in a single cylinder, four stroke vertical and air cooled Kirloskar diesel engine. The experimental results of this study showed that the MEMSO biodiesel has similar characteristics to that of diesel.

Performance Analysis of CI Diesel Engine using Methyl Esters and Carbonate Blends with Biodiesel as Substitute Fuel

KEYWORDS: Biodiesel, Palm stearin methyl ester, Dimethyl carbonate, Diesel engine, Performance. I. I NTRODUCTION Energy is the key input for technological, industrial, social and economic development of a nation. Five generations (125 year) ago, wood supplied up to 90% of our energy needs. Due to the convenience and low price fossil fuels use has fallen globally. The present energy scenario now is heavily biased towards the conventional energy sources such as petroleum products, coal, atomic energy etc. which are finite in nature besides causing environmental pollution. Of the available energy, the present energy utilization pattern is heavily biased for meeting the high energy requirement in urban and metropolitan cities. The extensive use of energy operated devices in domestic, industrial, transport and agriculture sectors in urban and rural areas have resulted in overall development of the society. The electricity available for forming operations and in rural and in urban areas is been generated using fossil and static energy resources such as petroleum oil, coal and atomic energy and to a limited extent by hydropower. These all sources have a great influence on our economy and environmental aspects. These have resulted in serious consideration for the use and the availability of various energy resources.

Performance and Emission Analysis of DI Diesel Engine Fuelled with Methyl Esters of Beef Tallow and Diesel Blends

2. Production of biodiesel from beef tallow In this research study, one-step transesterification of beef tallow with methanol was performed as KOH as catalyst. The diesel fuel was purchased from local Indian Oil fuel supply station and beef tallow was collected from slaughterhouse of Tamilnadu, India. Beef tallow was converted into methyl esters through base-catalyzed transesterification with methanol in the presence of KOH as catalyst. Before transesterification, beef tallow was heated to around 100-120°C for 1 hour and then sediments and impurities were filtered with cloth filter. After this process, a sample of 500 g of beef tallow, 95 g of methanol and 2 g of KOH were placed in a 1000 ml flat-bottom flask integrated with a magnetic stirrer- heater, digital thermometer. This mixture was stirred rigorously and heated to 70°C for 3 hours, and then it was allowed to cool to room temperature for 12 hour. Then the ester and glycerol layers were separated in a seperatory funnel. Finally methyl ester of beef tallow was purified with distilled water and drying to room temperature.

Emission characteristics of a compression ignition engine using methyl esters of rice bran oil and diesel blends

From the Figure-6, it is observed that smoke slightly increases with increasing load upto 75% and at full load increases drastically. The blends reduce the smoke than the neat diesel fuel. It is observed that smoke decreases for blends compared to diesel fuel, especially at high loads. The presence of atomic bound oxygen in biodiesl satisfies positive chemical control over soot formation. The tendency to generate soot by the fuel dense region inside a blend diffusion flame sheath is reduced, due improved mixing owing to better atomization and vaporization of blends. This is also attributed to the engine running overall ‘leaner’, with the combustion being now assisted by the presence of the fuel-bound oxygen of the ethanol and biodiesel even in locally rich zones which seems to have the dominating influence [Xiao Z, Boruff PA et al]. In-cylinder combustion photography showed lower luminosity flames for the blends, revealing the lower net soot produced percentages in its blends with diesel fuel [Xingcai L, Chen H et al]. This also proves the superior mixing of blends with air prior to premixed combustion phase and inbuilt oxygen in fuel results in more oxidation of soot particles to decreases the smoke level in the exhaust.

Evaluation of engine performance and emission studies of waste cooking oil methyl ester and blends with diesel fuel in marine engine

Evaluation of engine performance and emission studies of waste cooking oil methyl ester and blends with diesel fuel in marine engine

The 1 H-NMR spectrum of mixtures of Free Fatty Acid (FFA) compounds such as triacylglycerols as found in vegetable oils as well as animal fats and methyl esters are characterized by several salient regions of the fatty acid chains containing the signals of specific types of protons. The signals of these types of protons in the 1 H- NMR spectra of vegetable oils were used to quantity individual unsaturated fatty acids. Obviously, in the spectra of other saturated fatty acids and methyl esters, the intensity and the integration value of the signals of the methylene moieties change. With the change in integration value, and if the integration is sufficiently accurate, fatty acid chain length can be determined, although this is of little practical value. The 1H-NMR spectrum of methyl esters is virtually identical to that of stearic acid except for the strong singlet peak caused by the methyl ester protons at about 3.7 ppm. This peak of the methyl ester protons can be useful for quantification purposes transesterification reaction.

Influence of Al2o3 Additive on the Performance of a Diesel Engine Fueled with Jatropha Oil and Diesel Fuel

Demands to use the world’s fossil fuel reserves have been getting higher recently due to global industrialization and the increase of road vehicles running on petroleum-based fuels. Nowadays, fossil fuels are used mostly in the transportation sector; in which diesel is the most commonly used fuel. The fuel properties put great impact on engine performance. The Biodiesel cannot be directly used in the diesel engines because some of its fuel properties which poorly affect engine operation, but it can be blended with diesel fuel or alcohols. The present research is aimed at exploring technical feasibility of Jatropha oil in compression ignition engine without any substantial hardware modifications. In this work the methyl ester of Jatropha oil was investigated for its performance as a diesel engine fuel. The blends were obtained by mixing diesel and esterified Jatropha in the following proportions J10D90 which indicates jatropha biodiesel 10% and Diesel 90%, Similarly J20D80, J30D70, J40D60, J50D50, J75D25 and J100D0 were prepared. Experiments have been conducted with J0D100 (Pure diesel) and J100D0 (Pure biodiesel). The aluminium oxide additive is added to methyl ester of Jatropha to study the performance and exhaust emissions of diesel engine. Further the proportions extends to the different ratios of prepared biodiesel. Performance parameters like brake thermal efficiency, specific fuel consumption, brake power were determined. Exhaust emissions like CO 2 , CO, NO X and smoke have been evaluated.

Performance and Study of Diesel Engine Using Blends of Sunflower Oil with Diesel

Performance and Study of Diesel Engine Using Blends of Sunflower Oil with Diesel

Keywords- Internal Combustion Engine, Sunflower Methyl Esters, Transesterification, Performance. I. INTRODUCTION In the concern of current energy situation, major research is focused on sustainable energy solution with major prominence on energy efficiency and use of renewable energy sources. The diesel engines lead the field of commercial transportation and agricultural equipment due to its simplicity of operation and higher fuel efficiency. The consumption of diesel fuel is several times higher than that of petrol fuel. Due to the scarcity of petroleum products and its increasing cost, efforts are on to develop alternative fuels specially, to the diesel oil for fully or partial replacement. It has been originate that the vegetable oils are hopeful fuels because their properties are similar to that of diesel and are produced simply and renewably from the crops. Vegetable oils have equivalent energy density, cetane number, heat of vaporization and stoichiometric air–fuel ratio with that of the diesel fuel. None other than Rudolph Diesel, the forefather of diesel engine, validated the first use of vegetable oil in compression ignition engine. He works on the peanut oil as fuel for his experimental engine. During the World War II, efforts were made to use vegetable oils as fuel in diesel engines. Viscosity of vegetable oils is more than a few times higher than that of diesel. Viscosity of liquid fuels disturbs the flow properties of the fuel, such as spray atomization, resultant vaporization, and air–fuel mixing in the combustion chamber. Higher viscosity of oils had an adversative effect on the combustion in the present diesel engines.

There are varieties of species from which biodiesels can be made available. Biodiesels produce carbon dioxide (CO 2 ) during combustion but through the process of photosynthesis they recycle CO 2 . Hence they are called as carbon neutral. They are renewable and contain no sulphur. This characteristic of biodiesels can greatly reduce the existing environmental damage caused by acid rain [2]. If these biodiesels can successfully substitute conventional hydrocarbon based fuels in power generation sector they can be used as an emergency energy source. They will also play an important role in improving the financial status of the countries which are facing problem due to the shortage of conventional fuel.

Performance evaluation of a diesel engine fueled with methyl ester of castor seed oil

Performance evaluation of a diesel engine fueled with methyl ester of castor seed oil

6.5 Exhaust gas temperature Up to B05 the exhaust gas temperature was lower; thereafter it increased with increasing blends. This reveals that the effective combustion is taking place in the early stage of strokes and there is reduction in the loss of exhaust gas energy. This fact is reflected in brake thermal efficiency and brake specific fuel consumption results as well. When biodiesel concentration is increased, the exhaust gas temperature increases by same value. The highest exhaust gas temperature is observed as 265 _C in B20 blend at 145.29 kN load. The diesel mode exhaust gas temperature is observed as 187.7 _C at 145.29 kN load. The higher exhaust gas temperature may be because of better combustion of the castor ethyl ester as it contents oxygen molecule which helps in proper combustion.

Experimental Investigation on Diesel Engine using Methyl Fish Oil and its Diesel Blends

Email: ramu.anji78@gmail.com Abstract – The world is on the brink of energy crisis. The limited fossil fuels sources are unable to provide for the continuously increasing demand of energy. This demand has forced a search for an alternative source of energy, which is renewable, safe and non-polluting. Since vegetable oils and animal fats satisfy the major requirements, of C.I. engine fuel, they can be used as fuels alternative to diesel fuel. Fish oil is one of the sources for alternative fuels. From Hydrolysates of fish by-products contain a significant amount of oil, which can be extracted and converted into bio- diesel. The objective of this work was to determine the performance characteristics and emissions of a single cylinder, direct injection C.I. engine using methyl fish oil and their blends with diesel in varying proportions. These results were compared with the pure Diesel.

DEVELOPMENT OF MODEL FOR RUNNING DIESEL ENGINE ON RAPESEED OIL FUEL AND ITS BLENDS WITH FOSSIL DIESEL FUEL

DEVELOPMENT OF MODEL FOR RUNNING DIESEL ENGINE ON RAPESEED OIL FUEL AND ITS BLENDS WITH FOSSIL DIESEL FUEL

Abstract. Using ExtendSim simulation software a mathematical model is developed to determine the diesel engine operating parameters using rapeseed oil and its blends with fossil diesel fuel. The main difference of the model from other studies: developed module for determination of the ambient temperature when, using rapeseed oil fuel, fossil diesel has to be added to ensure the fuel pump operation and fuel flow through the system; developed analytical relationships to determine the residual gas molar calorific value, that provides continuous modelling process; specified empirical coefficients for constructing of engine power curves. The modelling results show that using pure rapeseed oil vehicles can be operated up to -14 ºC, with a blend RO80 (80 % rapeseed oil and 20 % fossil diesel fuel) – up to -17 ºC and so on. If the ambient temperature drops below -30 ºC, blends with rapeseed oil content of less than 30 % or pure diesel fuel have to be used. The reduction of the engine power and torque for the car VW Golf III 1.9TD engine is linear – each 10 % of rapeseed oil in fuel blend reduces the maximum power and torque of around 0.5 %. Using pure rapeseed oil the decrease is about 5 %. Keywords: rapeseed oil fuel, fossil diesel fuel, modelling, engine power, engine torque.

Investigation on the performance and Emission characteristics Of a diesel engine fuelled with vegetable oil methyl Ester blends and diesel blends

Abstract:- The present research work involves the production of methyl ester from various vegetable oils like Karanja oil and application of with diesel blend as alternative fuel in a diesel engine to investigate on the engine performance and emission characteristics. The methyl ester is obtained by base catalyzed transesterification process which is then blended with diesel in various volume proportions. The use of additive in blended fuels reduces the ignition delay and combustion period of a diesel engine and lowers the sulfur and nitrogen oxide emissions. The investigation shows that the brake thermal efficiency increases upto 80% load and then decreases. The highest brake thermal efficiency is obtained for diesel. The brake specific fuel consumption decreases upto 80% load and then increases. The exhaust gas temperature increases linearly with load and is highest for pure biodiesel. The engine emission analysis with the above test fuels show that CO, CO2, HC and smoke emissions increase with load for all test fuels. The NOx emission increases with load and is highest for pure biodiesel. From the results obtained during the ongoing experimental investigation it may be concluded that the Karanja oil methyl ester blends with diesel can be successfully used in a compression ignition engine without degrading the engine performance and emission.
