Investigation on aluminium oxide nano particles blended diesel fuel combustion, performance and emission characteristics of a diesel engine

Mozhi et al. [7], had investigated the performance, combustion and emission characteristics of a variable compression ratio engine using cerium oxide nanoparticles and carbon nanotubes as fuel-borne nanoparticles additives in diesterol (diesel–biodiesel–ethanol) blends. The Cerium Oxide nanoparticles were an oxygen donating catalyst which provides oxygen for the oxidation of carbon monoxide and absorbs oxygen for the reduction of nitrogen oxides. The activation energy of Cerium Oxide was to burn off carbon deposits and helps to prevent the deposition of non-polar compounds on the cylinder wall resulted in significant reduction of hydrocarbon and smoke emissions. Lenin et al. [8], performed the experiments on a single cylinder diesel engine for evaluation of diesel doped with metal additives MnO. Brake thermal efficiency was increased and the exhaust emission measurements for the fuel with manganese additive showed that CO is reduced by 37% due to higher carbon activation.

Support Vector Machine to predict diesel engine performance and emission parameters fueled with nano-particles additive to diesel fuel

Support Vector Machine to predict diesel engine performance and emission parameters fueled with nano-particles additive to diesel fuel

Abstract. This paper studies the use of adaptive Support Vector Machine (SVM) to predict the performance parameters and exhaust emissions of a diesel engine operating on nanodiesel blended fuels. In order to predict the engine parameters, the whole experimental data were randomly divided into training and testing data. For SVM modelling, different values for radial basis function (RBF) kernel width and penalty parameters (C) were considered and the optimum values were then found. The results demonstrate that SVM is capable of predicting the diesel engine performance and emissions. In the experimental step, Carbon nano tubes (CNT) (40, 80 and 120 ppm) and nano silver particles (40, 80 and 120 ppm) with nano- structure were prepared and added as additive to the diesel fuel. Six cylinders, four-stroke diesel engine was fuelled with these new blended fuels and operated at different engine speeds. Experimental test results indicated the fact that adding nano particles to diesel fuel, increased diesel engine power and torque output. For nano-diesel it was found that the brake specific fuel consumption (bsfc) was decreased compared to the net diesel fuel. The results proved that with increase of nano particles concentrations (from 40 ppm to 120 ppm) in diesel fuel, CO 2

Experimental Evaluation Of A CI Engine Running On Blends Of Diesel And Methanol Fuel With Copper Oxide Nano Particles

Experimental Evaluation Of A CI Engine Running On Blends Of Diesel And Methanol Fuel With Copper Oxide Nano Particles

Biofuel is the better alternative for the increased number of pollution and the decrease in fossil fuels. It has more oxygen content which leads to more emissions. And also, it has less calorific value with increased fuel consumption. So trans esterification process was done to obtain biofuel from the oil which has the specified properties as per the diesel engines. The biofuel obtained was used as a blend with diesel fuels in order to increase the performances of the fuel. But also, the nitrous oxide emissions and the soot particle emissions were increased when biodiesel was used in the diesel engines. To avoid this copper oxide additives were used in the blends. It was mixed with the biodiesel with the help of a magnetic stirrer. This improved the efficiency of the additives. It reduced the specific fuel consumption, increased brake thermal efficiency and leads to complete combustion. And also, the brake power increases with the increase in load when additive is added with the biodiesel. These additives increased the thermal efficiency and also increased the heat transfer capacity of the fuel. This is due to the main properties of the additives such as higher specific surface area, thermal conductivity, catalytic activity and chemical properties. And also, it increases the surface area to volume ratio that enables oxidation capacity.

Effect of Nano-Particles on the Performance and Emission of a Diesel Engine using Biodiesel-Diesel Blend

An experimental investigation was conducted in a six-cylinder, four-stroke diesel engine to establish the effects of Multi Wall Carbon Nano Tubes (MWCNT) with the dosing levels from 2.5 to 30 ppm with the waste vegetable oil (WVO) methyl esters fuel that was produced using the transestrification process, and subsequently, the WVO methyl ester was blended with diesel fuel in the proportion of 80% of diesel and 20% biodiesel by volume (B20). The Carbon nanotubes (with nano-structure (1/3) Chiral Metal and (2/3) semiconductor zigzag particles with the length of 10 μm and diameter of 5 nm with purity rate of 95%) were blended with the biodiesel fuel. The CNTs were blended with the biodiesel with the aid of ultrasonicator. The whole investigation was conducted in the diesel engine using the following fuels: neat diesel fuel (D100), 20% biodiesel and 80% diesel by volume (B20), as well as B20 and CNT blended fuels accordingly. The experimental results revealed a considerable enhancement in the performance parameters for the CNT blended biodiesel fuels compared to the neat biodiesel and neat diesel fuel (power increased up to 17%, torque increased 18%, bsfc decreased 38.5%). Emission parameters for the CNT blended decreased compared to neat diesel and neat biodiesel fuels (HC decreased up to 22%, CO emission decreased 14%). CNT nano-additives are considered as a propitious fuel-borne catalyst to improve the fuel properties, owing to their enhanced surface area/volume ratio, quick evaporation and shorter ignition delay characteristics that help to improve the performance parameters of engine and decrease emissions.

Experimental Analysis on Diesel Engine using Al2o3 Nano Particles with Hybrid Biodiesel

Experimental Analysis on Diesel Engine using Al2o3 Nano Particles with Hybrid Biodiesel

ever increasing diesel vehicle population, use of renewable fuels like vegetable oils has become more pertinent. Crude oil and petroleum products are going to become very scarce and costly to search and production. Although fuel economy of engines is greatly improved, increase in the number of automobiles alone dictates that there will be a great demand for fuel in the near future. The need of the development of alternative fuels for the IC-engine is concerned over the emission problems of gasoline engines. Combined with other air polluting systems, the large number of automobiles is a major contributor to the air quality problem of the world. A third reason for alternative fuel development is the fact that a large percentage of crude oil must be imported from other countries which control the larger oil fields. Bio-diesel is the essential fuel which have completed the health effects testing requirements of the US Clear Air Act. Bio-diesel provides reduction of unburnt hydrocarbons, carbon monoxide, and particulate matter used in a conventional diesel engine. It eliminates the sulphate fraction (as there is no sulphur in the fuel). There is no requirement engine modifications up to 20 percent blend. Bio-diesel could be made from crude/natural vegetable oils, crude/refined fats, high acidity oil/fats, recovered fried oils, animal fats and waste oils. Bio-diesel is a renewable fuel, biodegradable and non-toxic. Bio-diesel is produced by a simple chemical reaction between vegetable oil and alcohol in the presence of an acid or base as catalyst. It contains around 10% built-in oxygen by weight and has no sulphur and has excellent lubricity properties. Due to built-in- oxygen It is more efficient fuel than petro-diesel hence It contains higher cetane number than that of petro-dieselIt is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats. Bio Diesel confirm to ASTM D6751 specifications for use in diesel engines. The combustion behaviour of traditional liquid fuels with the addition of Nano scale energetic materials as fuel additives to enhance the performance and emissions in a diesel engine is an interesting concept. The addition of aluminium nanoparticles to diesel provides a large contact surface area with water and high activity for the decomposition of hydrogen from water during the combustion process. During combustion, alumina serves as a catalyst and the aluminium nanoparticles are denuded and decomposed the water to yield the hydrogen.The combustion of the diesel fuel mixed with aqueous aluminium . Nano metal oxide additives are reported to be successful in reducing diesel emissions. The metal based additives reduce diesel engine pollution emissions and fuel consumption values.

Experimental investigations of Jatropha biodiesel blends with Ethenol additives in Variable compression ratio diesel engine

Experimental investigations of Jatropha biodiesel blends with Ethenol additives in Variable compression ratio diesel engine

One can observe that the HC emitted by the diesel fuel was lower than it was for the corresponding biodiesel -diesel blended fuels, at all engine load conditions and all compression ratios. This is due to the higher cetane number of diesel fuel, which reduced the combustion delay; such a reduction was main reason to decreases the HC emissions in diesel fuel. Moreover, biodiesel blends too show HC emissions results slightly closer to diesel fuel due to the oxygen content in the biodiesel molecule, which leads to a complete and cleaner combustion. When the results of E -10 blended fuel was compared with E-6 blends, no such large variations were seen with HC emissions but for E-6 blends the HC emissions were slightly lesser than those for E-10 blends.

Experimental Studies on Emission and Performance Characteristics in Diesel Engine Using Bio-Diesel Blends And EGR (Exhaust Gas Recirculation)

Experimental Studies on Emission and Performance Characteristics in Diesel Engine Using Bio-Diesel Blends And EGR (Exhaust Gas Recirculation)

Bio-fuels have the potential to meet their growing energy demand in sustainable manner. Bio diesel is produced from plants, algae and animal fats. These have almost similar energy density, cetane number, heat of vaporization and stoichiometric air fuel ratio compared to mineral diesel fuel. Bio diesel has almost eliminates lifecycle of CO2 emissions. It has high cetane number which is a measure of fuel’s ignition quality. The high cetane number of biodiesel contributes to easy starting and low idle noise. Not only this, biodiesel has reduced emissions of carbon dioxide, carbon monoxide and hydrocarbons. Using pure biodiesel fuel in diesel engine sustains various problems like poor fuel atomization, piston ring sticking, injector choking and lubricating dilution. These problems are because of high viscosity, low volatility and low calorific value. Hence blending of biodiesel is done to reduce viscosity and improving other performances. It has been reported that transestrification is an effective process to overcome all these problems. But use of biodiesel in diesel engine has led to a great problem of increased NOx emission. So in order to reduce NOx emission various techniques have been developed like SCR, EGR etc. among this EGR is the best technique to reduce NOx emission.

Effects of Oxygenated Additives with Diesel on the Performance of D I Diesel Engine

Effects of Oxygenated Additives with Diesel on the Performance of D I Diesel Engine

The Table 1 summarizes some of the important properties of three selected oxygenated additives. It shows that, the comparison of boiling point, distillation range of all selected additives are within the distillation range of the base diesel fuel. The major properties that affect performance of the engine like vapour density, Cetane number; oxygen content and density are compared among these three additives in Fig. 1. High cetane number improves the cylinder pressure by decreasing and completing total combustion of fuel in shorter period. This is possible only with oxygenate additives due to higher quantity of oxygen availability that helps in proper mixing of fuel in the process of combustion. Addition of these additives also lowers the viscosity improves vaporization of diesel fuel that decreases delay in ignition.

Experimental Analysis Of Combustion Ignition Engine Using Bio-Diesel

Experimental Analysis Of Combustion Ignition Engine Using Bio-Diesel

The influence of load on brake power for different fuels is presented in Figure-2. It can be observed from the figure that as the load increases, brake power increases to the maximum at 70% load and then decreases for all the fuel samples. When the brake power produced by the engine at different loads for different mixtures of dual fuel is compared, it is found that the brake power increases up to B40 and then it decreases. When the brake power at different loads is compared for diesel and different combinations of dual fuel, it is noted that the brake power is higher for the dual fuel combinations from B5 to B30 than diesel. In the case of B40 the brake power is more or less equal to that of diesel. For the dual fuel combinations from B50 to B100, the brake power is less than that of diesel. Hence it can be concluded that the dual fuel combination of B40 can be recommended for use in the diesel engines without making any engine modifications. At the same time the cost of dual fuel (B40) can be considerably reduced than pure diesel.

Evaluation of performance & emission of neem oil methyl ester in a DI diesel engine. They observed that indicated lower brake thermal efficiency for B30, mainly due to its high viscosity compared to diesel. Higher brake thermal efficiency for NOME & B20 due to improved lubricity, reduced friction. Brake specific energy consumption of B30 is higher than diesel because of its lower calorific value, higher viscosity, density and boiling point. NOx emissions at full load for NOME, B20 & B30 were higher than diesel. Higher values of NOx are due to higher bulk modules of NOME (Bio-diesel) resulting in dynamic injection advance, changes in the composition, viscosity, density, oxygen content, calorific value of the fuel and combustion temperature .[1].

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

In this modern world of industries and technology the diesel engine plays a major role in various fields. It may be transportation (or) production e.t.c., with the increase of various applications to the diesel resources effects on the environment leading to effect like green house(3). Higher fuel efficiency in the diesel engine is achieved due to the high compression ratios along with relatively high oxygen concentration in the combustion chamber. However, these same factors results in high emission in diesel engine. The stringent emission norms have been an important driving force to develop the internal combustion engines more environment friendly (12). The main pollutants from diesel engines are Carbon Monoxide and Hydro Carbons. The use of fish oil as an alternative to diesel fuel is a new concept. In fact early engines were demonstrated with vegetable oils. In a developing country such as India where mass transportation plays a key role, the suitability of alternate fuels for a diesel engine likes cetane number and calorific value similar to diesel(7).
