Abstract: Proper lubrication in the machine is very important. Without proper lubrication in the machine reduces the performance and life of machine. The working of machine in good condition depends on the quality of lubricants and condition of machine. The lubricating properties of lubricants decide the time interval of lubrication. Hence rather than the conventional way of changing the lubricant at the fixed interval, it is recommended that the oil be changed based on their lubricating properties. Viscosity and Total Base Number (TBN) are two very important properties which affect the useful life of the oil. Total Base Number (TBN) is measure of alkaline reserve present in the oil. TBN is defined as the amount of KOH required to balance HCl that in turn will balance all the basic components present in one gram of the lubricating oil. With time this basic component of the oil gets reduced, so it is a good parameter to assess the deterioration of oil. Tom (2007) described how FTIR can be used for oil analysis and suggested the selection of correct parameters for specific applications. The present paper proposes to use Fourier Transform Infrared (FTIR) spectroscopy to find TBN value of the oil.

In this paper the trends in TBN with the transmittance of selected peak will be found out and the equations of the trend line will give the TBN value at any particular value of transmittance of FTIR spectra. So the proposed method will be more economical, simpler fast and compatible to be a part of online oil analysis system.

Abstract: Adhesive bonded joints with laminated FRP composites play a significant role in many structural applications especially in space, aircraft and automobile industries. However, designing the composite bonded joints is quite complex, because their performance is limited by the characteristics of the composite laminate adherends and bi-material interface which usually have low interlaminar strengths. The project aims at detail Analytical, FEM analysis and experimental analysis of adhesive joint. The following are the main objectives of the project. Adhesive joints are expected to retain a significant proportion of their load bearing capacity for the entire duration of the service life of the bonded structure..The single-lap shear test is the most widely used method for producing in shear strength data on adhesively bonded joints. The E-glass plate manufactured consist of combination of different mats prepared by mixing of proportionate combination of cobalt resin & hardener which have more strength than adhesive material AV-119 of varying thickness. The E-glass material plates of varying thickness where joined by lap join of varying thickness formed using material AV-119Variations of this test method are included in both national and international standards . The single-lap specimen is easy to prepare and test. Special care is needed to ensure that bond line thickness is uniform. Adherend surfaces should be prepared according to ISO 4588 for metals and ISO 2818 for polymer matrix composites (PMCs). Testing is conducted using standard tension/compression mechanical test equipment with a suitable pair of self-aligning to hold the specimen.

Abstract: This paper deals with the selection of aerofoil based on Lift and Drag Characteristics. Two different type of aerofoils such as ordinary Aerofoil and Supercritical Aerofoil that are being used in currently are selected namely NACA0012 and NACA SCA0714 are being considered for analysis. The tests are conducted using ANSYS FLUENT simulation software. The two aerofoils are tested at various Angles of Attack (-10°, -5°, 0°, 5°, 10°) and at two different flow conditions. Finally, the aerofoil with its angle of attack is tabulated with its lift and drag coefficients. Thetest results of both aerofoils are compared and results are concluded.

Abstract: This paper is based on the general overview about previous research papers to improve the performance and emission characteristics of an IC engine using different ceramic coating and biodiesel blend. In the modern world automobile manufacturer industry may not produce an effective performance of IC engine. Because of the major reason is, when the friction would be developed at the high speed working condition of an IC engine. Due to this mechanical components are piston, connecting rod, cylinder head, valves and crankshaft are mainly affected and reduced the life span. However it is very difficult to avoid this problems but minimize the problem based on applying the different ceramic coating on the surface of mechanical components, also improve the emission characteristic and reduce the specific fuel consumption of an IC engine by using an effective biodiesel.

Abstract: This major project involves the complete system design and construction of a Missile detector and destroys system. We aimed to develop a compact and highly mobile defense system that allows operational flexibility. The system can autonomously track and shoot at moving targets, while also allowing a user to remotely access and control the gun. The mobility, hardiness, and functionality of this system allows a reliable replacement for human beings in harsh and hostile environments; ultimately sparing a life.

Abstract: Microstructural evolution in the ECAP processed 6061 alloys is one of the severe plastic deformation process where remarkable strengthening is achieved. In this study, a review is carried out on designing and influence of ECAP on mechanical properties. The studies reveal   that Number of stages in ECAP process also affects the microstructure & Tensile properties. The ductility can also be improved by adequate refining microstructure & mechanical properties.

Abstract:-With modernization and increase in the number of automobiles worldwide, the consumption of gasoline has enormously increased. As petroleum is non renewable source of energy and the petroleum reserves are scarce nowadays, there is a need to search for alternative fuels for automobiles. Work has been done in using a lot of other fuels to be used in IC engines. Thus this work is an attempt for the use of LPG and Acetylene as alternative resources such that it can be useful for the people in near future. This paper represents an investigation on the performance of SI engine fuelled with LPG and Acetylene individually with petrol as an alternative fuel.
