Experimental Investigation Of A Diesel Engine Using Nerium Oil As Alternative Fuel

Experimental Investigation Of A Diesel Engine Using Nerium Oil As Alternative Fuel

Rapid depletion of conventional energy sources, along with increasing demand for energy is a matter of serious concern. To solve both the energy concern and environmental concern, the renewable energies with lower environmental pollution impact should be necessary. Biodiesel is renewable and environmental friendly alternative diesel fuel for diesel engine. It can be produced by trans-esterification process. Trans- esterification is a chemical reaction in which vegetable oils and animal fats are reacted with alcohol in the presence of a catalyst. The products of reaction are fatty acid alkyl ester and glycerin, and were the fatty acid alkyl esters known as biodiesel.

Experimental study of the bio additives in biodiesel fuel on performance and emissions characteristics of diesel engine

Experimental study of the bio additives in biodiesel fuel on performance and emissions characteristics of diesel engine

This study is about the effect of bio additives; Di Methyl Poly Siloxane Power (DMPS Power) and Palm Oil Methyl Ester (D20 Booster) performances and emissions in diesel engine fueled with Bio Diesel Fuel (BDF) i.e., Crude Palm oil, Jatropha Curcas oil and Waste Cooking oil. Furthermore, due to alternative fuels for diesel engine are becoming increasingly important because of diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum-fueled engines. Several developed countries have introduced policies encouraging the use of BDF made from grains, vegetable oil or biomass to replace part of their fossil fuel use in industries in order to prevent environmental degradation by using cleaner fuel and to reduce dependence on imported, finite fossil supplies by partially replacing them with renewable, domestic sources. The DMPS and D20 Bio-additives can remarkably improve the fuel economy of Compression Ignition (CI) engine while operating on all kinds of BDF. The power output of BDF depends on its, blend, quality, and load conditions under which the fuel consumed. Hence, the performance, combustion characteristics and emissions of diesel engine learnt under different speed and load conditions.

Experimental Investigation on Diesel Engine using DMC as a Fuel Additive in Tamarind Seed Oil Methyl Ester

the utilization of Biodiesel and it blends in diesel engines have done. Raju et al. [9] conducted experiments on compression ignition engine with mahua seed oil as alternate feedstock and reported that the mahua seed bio- fuel blends shown enhanced BTE and lowered exhaust emissions when analyzed with conventional diesel. Biodiesels contain inherent oxygen content; better lubricity and higher Cetane are the main reason for the improvement in thermal efficiency with biodiesel However, most of the cases the work is on to use as single biodiesel and blends. From literature studies [10-14], biodiesel play a vital role in diesel engine. Finally, it is concluded that biodiesel is one of the potential alternative fuel for the diesel to minimize the tailpipe emissions towards the sustainable green environment. The characteristics of biodiesel are close to mineral diesel, and therefore tamarind seed oil become a potential fuel source to replace partially or completely the mineral diesel if need arises.

Optimization of Injection Pressure and Injection Timing of a Diesel Engine Fuelled with Optimized Blend of B25 Cotton Seed Oil Biodiesel

Optimization of Injection Pressure and Injection Timing of a Diesel Engine Fuelled with Optimized Blend of B25 Cotton Seed Oil Biodiesel

Globally the demand for diesel and petrol is alarming due to speedy depletion of fossil fuel and hyper increase of automobiles in the current years. It results in seeking an alternate for fuel that led to many findings of alternative fuels. The previous researchers have exposed the utility of vegetable oils for engines as an alternative for diesel fuel. However, there is a constraint in using vegetable oils in diesel engines due to their high viscosity and low volatility. In this study, raw cotton seed oil is converted into biodiesel (Methyl Ester of Cotton Seed Oil) through transesterification process and finds the impact of injection pressures (190, 200, 210, 220 and 230 bar) and injection timings (21 o , 23 o and 25 o bTDC) on combustion, performance and emission parameters of optimized blend (B25) of cotton seed oil biodiesel with diesel in a single cylinder diesel engine. From the investigation, it is found that in a diesel engine the optimum injection pressure is 200 bar and injection timing is 23 o bTDC for the optimized blend of B25 cotton seed oil biodiesel and could be used as an alternative fuel with no modification of the diesel engine.

from vegetable oils [6-8]. It has many advantages that include low emissions, biodegradable, non-toxic, environment friendly and better lubricity [9]. Petroleum fuel supply has become scarce, and its use has been associated with the increase in environmental problems. Diesel engines are widely used as power sources for medium and heavy duty applications [10]. The viscosity of vegetable oils is many times higher than that of diesel fuel. The viscosity is reduced when triglycerides are converted into esters by transesterification reaction. Thus, three smaller molecules of ester and one molecule of glycerin are obtained from one molecule of fat/oil [11].

The Effects of Fatty Acid Methyl Ester Petrodiesel Blend on the CO and NOx Emissions Toxicity in CI Diesel Engine

The Effects of Fatty Acid Methyl Ester Petrodiesel Blend on the CO and NOx Emissions Toxicity in CI Diesel Engine

After ambient temperature and pressure were measured and the biofuel blends density and calorific values determined, the water pumps to the engine and dynamometer were turned on. The engine was connected to the battery terminal. The start button was pressed while the choke is in return position. The throttle was placed at relative low speed, 800 rpm and allowed to run idly for about 15minutes to attain a uniform temperature. The value of the torque was recorded. The time for a given value of the fuel to be consumed at the speed of 1500 rpm was measured by using the stopwatch to measure the time for the fuel to move between appropriate spacers while supply tank fuel gauge is turn off. The manometer reading, oil temperature and oil pressure were measured. Also the readings on the two water systems for both engine and dynamometer viz.: the water inlet temperature, water outlet temperature and water flow rate/head were measured. The process starting from recording the torque was expected for higher torque values: 10, 20, 30, 40 Nm.

An Experimental Investigation On Emissions Of Neat Mahua Biodiesel Using Urea-SCR

An Experimental Investigation On Emissions Of Neat Mahua Biodiesel Using Urea-SCR

The world today is in need of alternate fuel sources because of fuel depletion and increase of fuel demand. The yearly reports in pollutants of atmosphere are also in increasing trend, the need is to develop the eco- friendly fuel to meet the fossil fuel depletion.These reasons increase the attention towards vegetable oil as an alternate fuel source. Biodiesel is the name of clean burning fuel, produced from domestic renewable resources. It contains no petroleum but it can be blended at any level with petroleum diesel to greater biodiesel blend. It can be used in CI engine with no major modifications. It is simple to use, bio degradable, non-toxic and essentially free of sulphur and aromatics. The choice of vegetable oil as engine fuel naturally depends upon the local conditions prevalent availability of a particular vegetable oil in excess amount. There are various oils which are being considered worldwide for use in the engines. But Mahua biodiesel is one of the most promising biodiesel options among these. Mahua (Madhuca Indica) is one of the forest-based tree- borne non-edible oils with large production potential of about 60 million tons per annum in India [1]. Many researchers investigated the effects of diesel-biodiesel blends on performance and emission characteristics in diesel engine and concluded that partial or full replacement of diesel with biodiesel is feasible [1-10].The major properties of Mahua biodiesel include calorific value, diesel index, flash point, fire point, cloud point, pour point, specific gravity, and kinematic viscosity. The various physicochemical properties of diesel and Mahua biodiesel are measured and listed in Table 1 for comparison.

From the study conducted by Rajesh kumar et al [6] using octanol as blend component with diesel, he suggested that the usage of octanol had prolonged the ignition delay thereby creating higher cylinder pressure resulting in an increased heat release rate. Adding octanol resulted in the reduction of emission along with increase of performance for naturally aspirated mode. The results of EGR mode showed reduction of NOx and smoke emission but increased CO, HC and BSFC rates. Sundar R et al. [7] conducted an experiment using diesel/hexanol blends with varying hexanol percentage by volume in CI engine. He found a substantial reduction in smoke opacity whereas a surge in NOx emission along with improvement in performance using hexanol/blends over diesel. Jeya Jeevan et al. [8] had investigated the performance and emission characteristics of diesel engine operating with biodiesel/diesel blends, diesel/butanol blends and diesel/pentanol blends as fuel respectively. Deep et al. [9] found reduction in NOx and CO emissions of single cylinder diesel engine when octanol is blended in neat diesel in comparison to diesel. BSFC is found to decline for lower fraction of octanol but increases with increment in octanol proportion.

Experiment Investigation of Combustion Characteristics Analysis of Blend of Diesel with Low Concentration Linseed Methyl Ester at Different Compression Ratio on VCR Diesel Engine

Biodiesel is a safe alternative fuel to replace traditional petroleum diesel. It has high-lubricity, is a clean-burning fuel and can be a fuel component for use in existing, unmodified diesel engines. More specifically, biodiesel is defined as an oxygenated, sulfur-free, biodegradable, non- toxic, and eco-friendly alternative diesel oil. Chemically, it can be defined as a fuel composed of mono-alkyl esters of long chain fatty acids derived from renewable sources, such as vegetable oil, animal fat, and used cooking oil designated as B100, and also it must meet the special requirements such as the ASTM and the European standards [5]. The demand for diesel is five times higher than the demand for petrol in India. But while the ethanol industry is mature, the biodiesel industry is still in its infancy. India's current biodiesel technology of choice is the transesterification of vegetable oil. The Government of India has launched an National Biodiesel Mission in 2003 comprising six micro missions covering all aspects of plantation, procurement of seed, extraction of oil, trans- esterification, blending & trade, and research and development to replace 20 percent of petroleum fuel consumption with biofuels (bioethanol and biodiesel) by end of 12th Five-Year Plan (2017).

REVIEW ON PERFORMANCE AND ANALYSIS OF C.I. ENGINES BY USING DIFFERENT BIODIESEL (ALTERNATE FUEL)

REVIEW ON PERFORMANCE AND ANALYSIS OF C.I. ENGINES BY USING DIFFERENT BIODIESEL (ALTERNATE FUEL)

5.2 T. Mirunalini et al [2]:- This paper presents the research work on Jatropha oil as a source of biodiesel as an alternate to diesel fuel for its application in diesel engines. Jatropha oil can be obtained from Jatropha curcas plant. In this paper the property of jatropha oil are studied and is used in diesel engine and the results are investigated. Jatropha oil being highly viscous and low volatile makes it difficult for its direct application in the engine. The direct use of Jatropha oil in diesel engine may result into poor vaporization and atomization of the fuel during the injection process and may even harm the engine parts. To overthrow this, Jatropha oil is blended with diesel oil. Blending will result into the lowering of viscosity and it also increases the cetane number of the fuel. The researchers have created a blended mixture by amalgamating diesel oil with different proportions of clean jatropha oil. They have used the blended biodiesel fuel to run a 4 stroke single cylinder engine and at the end the performance and emission of the engine is reviewed. In order to load the engine electric dynamometer is used. They have initially carried out this experiment by using pure diesel oil and later blended mixture is used and comparisons are done.

EMISSION AND PERFORMANCE CHARACTERISTICS OF A CI ENGINE FUELLED BY COTTONSEED OIL METHYL ESTER AND DIESEL FUEL BLEND

EMISSION AND PERFORMANCE CHARACTERISTICS OF A CI ENGINE FUELLED BY COTTONSEED OIL METHYL ESTER AND DIESEL FUEL BLEND

Many researches of vegetable oil fuels have investigated that the vegetable oils can be used as an alternative fuel for diesel engines. The viscosity of crude vegetable oils is rather high than diesel fuel. High viscosity has negative effect on atomisation quality, and so engine performance and exhaust emissions are affected badly and become failure on engine parts. To decrease of viscosity of cottonseed oil methyl ester was produced and tested as alternative fuel in a single cylinder, four strokes, air-cooled diesel engine. Engine tests carried out at full load- different speed range, the engine torque and power of cottonseed oil methyl ester with diesel fuel blend was lower than that of diesel fuel in range of 2-3 % and specific fuel consumption was higher than that of diesel fuel of approximately 3 %. CO 2 , CO and NO x emissions of cottonseed methyl ester were lower than that of diesel fuel.
