The present work reports on the continuous abrasives wear behaviour of Al-SiCp composites with 5 to 30 wt. % of SiC particulates. A pin-on-drum wear-testing machine was designed and fabricated to study the effects of wt. % of SiCp, load, relative velocity and abrasive particle characteristics on abrasive wear behaviour of Al-SiCp composite with 5 to 30 wt. % of SiCp. The 6040Al-SiCp composite samples were fabricated through stir die casting process using induction furnace melting. 6040 Al-alloy was used as matrix material, which was reinforced with SiC particles of 120μm mean particle size. The Al-SiCp composite specimens with 5, 10, 15, 20, 25 and 30 wt. % of SiCp were cast in the shape of cylindrical pins for abrasive wear testing. The specimens were machined to step pin of 5 and 16 mm diameter and length was 10mm and 45 mm. The specimens were slid against alumina oxide abrasive paper pasted on the drum with four different grit sizes i.e. number 120, 100, 90 and 80 at sliding velocity of 0.2, 0.4, 0.6 and 0.8 m/seconds respectively under different loads of 4.5 N, 9N, 14.5N and 18.5N for a fixed sliding distance of 0.5 m using Pin-on-drum wear testing machine. The weight loss due to wear of pins was measured using an electronic balance of 0.001 mg accuracy. The coefficient of friction was determined during the test using load cell unit. The results of the wear tests showed that the abrasion wear resistance decreases with increase in the relative abrasive penetration depth, until a critical value, above which, the abrasive wear resistance was almost independent of the penetration depth. The wear resistance was found to increase with the increase in weight percent of SiCp from 5 to 20 wt. %. However the wear resistance was decreases on further increase in wt. % of SiCp from 20 to 30 wt. % due to removal of loosely bonded SiC particles. The wear resistance was also found to increase with increase in normal load and decreased with increasing in sliding velocity. Abrasion by the Al2O3 particles and cavitations due to dislodging of SiC particles was identified as the dominant wear mechanism from the scanning electron micrographs of worn surfaces of the composites.

Vapor absorption refrigeration systems (VARS) are having great advantages as they use low grade energy like heat, very few moving parts, and almost its performance is independent of refrigerating load fluctuations. However, the working characteristics of vapor absorber and generator significantly affect its overall performance and compactness. From the intensive review of existing literature, it is found that very few studies are reported for designing a water cooled plate type bubble absorber which can be used for R134a-DMAC. This report describes a simplified procedure to design R134a-DMAC plate type bubble vapor absorber. The procedure includes solving techniques of the mass and energy equations related with VARS. The heat and mass transfer characteristics along the length of absorber of R134a-DMAC mixture, and coolant are obtained by using the thermo-physical properties experimental correlations for enthalpy, dew and bubble point temperatures, specific heat, density, viscosity, thermal conductivity and mass diffusivity. In addition, the coefficients of heat and mass transfer are found by employing the empirical correlations which are explained in terms of temperature, pressure and mole fraction. All the equations and the correlations are solved by splitting the whole absorber into small control volumes and subsequently each control volume is divided into liquid, vapor and coolant segments. A computer program in MATLAB is developed and tested to find the various specifications of absorber like number of plates, width, height and thickness of plates, coolant and solution passage, etc.

A single cylinder vertical air-cooled diesel engine was modified to use Methanol fuel mode to study the performance, emission, and combustion characteristics. The primary fuel, Methanol with air, compressed, and ignited by a small pilot spray of diesel. Dual fuel engine showed a reduction in oxides of Nitrogen and smoke in the entire load range. However, it suffers from the problem of poor brake thermal efficiency and high hydrocarbon and carbon monoxide emissions, particularly at lower loads due to poor ignition. In order to improve the performance at lower loads, a glow plug was introduced inside the combustion chamber. The brake thermal efficiency improved by 3% in the glow plug assisted dual fuel mode, especially at low load, and also reduced the hydrocarbon, carbon monoxide, and smoke emissions by 69%, 50% & 9% respectively. The presence of glow plug had no effect on oxides of Nitrogen.

Machining of polymeric materials has become increasingly important in any engineering industry subsequently the prediction of surface roughness then the material removal rate. Surface quality has greater influence on components which are coming in contact with each other. So it becomes necessary for measuring and studying machined surfaces and its behavior. In this experimental study, turning operation was carried out using carbide cutting tool on a carbon fiber reinforced polyester resin to measure its surface roughness. Combination of machining parameters that offer the good surface finish was found out using, and then the highly influential machining parameter that affects the surface characteristics also was found out using ANOVA analysis. A fuzzy rule based model was developed to predict surface roughness of parts which are made by turning operation. It was observed that there exists a good correlation between the surface roughnesses obtained from experimental as well as fuzzy rule based prediction. This experimental study also presents the influence of machining parameters on material removal rate.

In recent years advanced polymer material composites are used to manufacture a fishing boat in glass fiber with polyester resin. This paper presents a modified laminate structure from existing laminate structure and to produce the boat of 650 Kg in the fiber-reinforced polymer. The analytical expression for calculation of stiffness and stress for both laminate plates were derived. The failure analyses were carried out for both the laminate plate by using maximum stress criteria to avoid failure during real time application of laminate structure. The fiber materials, which are used to prepare a laminates, are chopped strand mat (CSM) glass fiber (random orientation), woven roving mat (WRM) glass fiber (Cross ply orientation of 0° & 90°) and unidirectional glass fiber (UDF) with polyester resin. The existing composite plate and modified composite plate were prepared by 16% and 23% of fiber volume fraction respectively. The manufacturing method was used to produce a laminate plates is by hand lay-up process. The laminates were prepared by different stacking sequence and thickness to produce a symmetric and non-symmetric laminates. The laminate structures are [5 CSM, 1 WRM] and [4 CSM, 1UDF]. The specimens were cut as per ASTM and BS standards from the both laminates and tested in Instron Universal Testing Machine. The mechanical properties such as Tensile, Flexure and Interlaminar shear of composite were tested and compared. It was found that a modified symmetric laminate is a suitable laminate for the manufacture of fishing boat.

A wavelet-based vibration analysis was done for Defense Applications. Vibration measurements were carried out in MSL Engine test bed in order to verify that it meets the specifications at different load conditions. Such measurements are often carried out in connection with troubleshooting in order to determine whether vibration levels are within acceptable limits at given engine speeds and maneuvers. A State-of-the-art portable Vibration Data Recorder is used for data acquisition of real-world signals. This paper is intended to take the reader through the various stages in a signal processing of the vibration data using modern digital technology. Vibration signals are post-analyzed using Wavelet Transform for data mining of the vibration signal observed from accelerometers. Wavelet Transform (WT) techniques are applied to decipher vibration characteristics due to Engine excitation to diagnose the faulty bearing. The Time-Scale analysis by WT achieves a comparable accuracy than Fast Fourier Transform (FFT) while having a lower computational cost with fast predictive capability. The result from wavelet analysis is validated using the LabVIEW software.

Biodiesel is renewable and environmental friendly alternative diesel fuel for diesel engine. It can be produced from food grade vegetable oils, inedible oil, animal fats and waste or used vegetable oils, by transesterification process. Transesterification 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. In this project esterified Nerium oil is used as an alternate fuel. A single cylinder stationary kirloskar engine is used to compare the performance and emission characteristics between pure diesel and Nerium blends. In this project selection of suitable nerium blend and selection of optimized injection timing for the blend is done. The Nerium oil blends are in percentage of 20%, 40%, 60%, 80%, and 100% of Nerium oil to 80%, 60%, 40%, 20% & 0% of diesel. From this project it is concluded that among all nerium and diesel blends 20% of nerium and 80% of diesel blend at 30º BTDC gives better performance nearing the diesel. When comparing the emission characteristics HC, CO is reduced when compared to diesel, however NOx emission is slightly increased when compared to diesel. Hence Nerium blend can be used in existing diesel engines with minimum modification in the engine. It also describes the usage of non-edible oil to a greater extent.

This paper deals with the introduction of a new technique to supply the energy whenever required by the system. In normal driving of an automobile on roads we are utilizing the power assistance for steering only about 15 to 20% of the time in comparison with full running time of the automobile. But the power steering pump which is drawing the power for running (with the same speed) as it is connected with the engine. To utilize the power whenever required, the pressure detecting device which is connected with the line of power steering pump gives signal to the electronic unit to act according to the system demand. This energy saver is device restricts the power drawing from the engine whenever it is nor required and connects whenever it is not required and connects whenever it is required. This in turn reduces the fuel consumption of the vehicle to certain extent as we are not drawing power from the engine for running the power steering pump. This energy saver operates in connection with the pressure to be maintained in the system which is required for the elimination of the fatigue of the driver while steering. The validation of the energy saver is done by experimental basis and results analyzed.
