The exhaust system must work properly for a vehicle to run reliably and safely. Modern exhaust systems typically clean up the gases before releasing them into the environment. Sometimes modifying an exhaust system helps the gases flow more smoothly and provide better performance and efficiency.Item Multi Purpose Agricultural Robot(2015-12-28T14:26:35Z) Chetan Kumar S, Tarihal; Nandeesh, P; Naveen, M; Vineet K, GokhaleIn this project described here is quite useful in the agricultural field. The project aims on the design, development and the fabrication of the robot which can dig the soil, put the seeds, leveler to close the mud and sprayer to spray water, these whole systems of the robot works with the battery and the solar power. More than 40% of the population in the world chooses agriculture as the primary occupation, in recent years the development of the autonomous vehicles in the agriculture has experienced increased interest. The vehicle is controlled by Relay switch through RF transmitter and RF receiver input. The language input allows a user to interact with the robot which is familiar to most of the people. The advantages of these robots are hands-free and fast data input operations. In the field of agricultural autonomous vehicle, a concept is been developed to investigate if multiple small autonomous machine could be more efficient than traditional large tractors and human forces. Keeping the above ideology in mind we propose to design a unit with the following features: Ploughing is one of the first steps in farming. During this process we till the land and make it ready for the seed sowing. By tilling we mean that a plough will be used which will have teeth’s like structure at the end and will be able to turn the top layer of soil down and vice-versa. Seed sowing comes next where the seeds need to be put in ground at regular intervals and these needs to be controlled automatically. Limiting the flow of seeds from the seeds chamber is typically doing this. Mud leveler is fitted to close the seeds to the soil and to level the ground. Water pump sprayer is used to spray the water. This arrangement will be consisting of various motors, gears and pipes and its controlling mechanism.Item Design Of 5 Axis Robotic Arm HIV Testing(2015-12-28T14:22:38Z) Imran, SayedThis project is to design and develop a "Robotic Arm for Pick and Place” application for HIV testing using AURDINO-UNO microcontroller.

Starting from the 70’s, there have been several attempts to convert engines for hydrogen operation. Together with the development in gas injector technology, it has become possible to control precisely the injection of hydrogen for safe operation. Since the fuel cell needs certain improvements before it is widely used in vehicles, the conventional internal combustion engine is to play an important role in the transition. This study examines the performance characteristics and emissions of a hydrogen fueled conventional spark- ignition engine. Slight modifications are made for hydrogen feeding which do not change the basic characteristics of the original engine. Comparison is made between the gasoline and hydrogen operation and engine design changes are discussed. Certain remedies to overcome the backfire phenomena are attempted. Hydrogen gas combined with the standard air/fuel mixture increases the mileage. This form of alternative fuel is provided by a hydrogen generator mounted in the vehicle. Once set up is ready, the hydrogen gas (fuel) will be produced from water, an electrolyte compound, and electricity supplied from a battery provided. Here we are designing a mixed fuel two wheeler engie.ie in a conventional SI engine we are incorporating traces of hydrogen along with gasoline in order to minimize the consumption of gasoline as well as to increase the power of vehicle. Here in addition, a hydrogen generating unit is made to produce hydrogen .It is actually an electrolysis unit having high grade stainless steel/graphite/semiconductors as electrodes in a closed container and mixture of distilled water & suitable ionic solution(KOH or NAOH) as electrolyte. Power for electrolysis is taken from an additional battery provided (12V).Item Use Of 3D Printing Components In Miniature Aerial Vehicle (MAV)(2015-12-28T14:11:48Z) Mahar Noyal, Sunny3D printing, also known as rapid prototyping is a form of additive manufacturing technology is any of various process used to make a three dimensional object. In this process we use additive process that is addition of material to develop the product is used, in which successive layers of material are laid down in a computer control. These objects can be almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot. Usually the term 3D printing refers to the process that sequentially deposit material onto a powdered bed with inkjet printer heads. More recently the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering based processes. This project presents a manufacturing of prototype of Micro Aerial Vehicle (MAV) using various Mechanisms of Fused Deposition Modeling (FDM) rapid prototyping process. The material used to produce various Mechanisms is Acrylonitrile butadiene styrene (ABS). The CAD files are used in Rapid Prototyping techniques for design and manufacturing of the various Mechanisms. The Rapid Prototyping process involves translation of the CAD file into .stl format. The model is sliced into multiple horizontal layers followed by layer by layer addition of material to form a prototype. Use of this CAD data in Rapid Prototyping Techniques minimize the time to market and further scope for research and development of time of new products.Item Structural Analysis And Process Planning For A Bracket Of An Aileron Flight Control System(2015-12-28T14:07:13Z) Anurag, YadavPresent aerospace industry demands for the components that impart more strength to a structure or the system with high service life and least possible weight.

Generally, a composite material is composed of reinforcement embedded in a matrix. The matrix holds the reinforcement to form the desired shape while the reinforcement improves the overall mechanical and wear properties of the matrix. When designed properly, the new combined material exhibits better properties than would each individual constituent element. To improve the properties further, ceramic fillers could be added to the matrix. The main objective of the present work is to develop and characterize a new class of epoxy matrix composites reinforced with natural fiber and titanium dioxide filler. Mechanical properties were evaluated by conducting tensile test in accordance with ASTM D638, flexural test in accordance with ASTM D790, Impact test and Shore D hardness test in accordance with ASTM D-2240. The results suggested that the addition of titanium dioxide filler to natural fiber reinforced epoxy composites improved the mechanical strength.Item CFD Analysis Of Di Combustion Chamber Of Diesel Engine To Improve The Performance By Its Different Piston Crown Geometries.(2015-12-23T14:10:21Z) Darshit, Bhatti; Dwaipayan, Adak; Chinthan, Patel; Nagaraj, KuntojiThis project investigates Experimental analysis of different piston bowl geometries of DI Combustion chamber of Single cylinder diesel engine. From the various experiments it has been found that efficiency is directly correlated with higher turbulence velocity & lesser emission of NOx, CO, CO2 & HC. This project mainly focuses on combustion analysis of piston crown geometry and improving combustion efficiency and thus improving the overall efficiency of the engine. Thus by varying the piston crown geometry, efficiency of the engine can be analyzed which comparatively results in lesser emissions, higher torque & brake power which ultimately increases Efficiency.Item Study On Mechanical And Tribological Behavior AA-7075 Reinforced With Aluminium Oxide(2015-12-23T14:04:52Z) Bharathdwaj, GManufacturing of aluminum alloy based casting composite materials via stir casting is one of the prominent and economical route for development and processing of metal matrix composites materials. Properties of these materials depend upon many processing parameters and selection of matrix and reinforcements. Literature reveals that most of the researchers are using 2, 6 and 7xxx aluminum matrix reinforced with SiC particles for high strength properties whereas; insufficient information is available on reinforcement of “Al2O3" particles in 7xxx aluminum matrix. The 7xxx series aluminum matrix usually contains Cu-Zn-Mg. Therefore, the present research will be conducted to investigate the effect of elemental metal such as Cu-Zn-Mg in aluminum matrix on mechanical properties of stir casting of aluminum composite materials reinforced with alpha "Al2O3" particles using simple foundry melting alloying and casting route.Item Closed Loop Multi Point Fuel Injection Test Bench Setup(2015-12-23T13:59:35Z) Avinash, S; Gagan Deep, B Y; Hemanth Kumar, T NFuel injection is a technology used in internal combustion engines to mix the fuel with air prior to combustion. Fuel injection may be single point where the fuel is injected using one nozzle or multi point where each cylinder has its own injector in the inlet manifold. The nozzle may be opened using the pressure in the fuel system or there may be solenoid on the injector that will pulse it open and closed in duty cycle according to the desired fuel requirements. The components of fuel injection equipment are fuel pump, fuel injector, feed pump. Fuel injection pumps and injectors are used to inject fuel into the engine cylinder. In the fuel injection equipment section working of the fuel pumps and calibration of fuel pump is carried out and injectors are tested according to the ideal delivery conditions of the equipment. The project entitled “Closed loop Multi Point Fuel Injection bench setup”. In this project we are studying the working of 4 cylinder engine which consists of a fuel tank, a fuel pump attached to the tank, an engine block made of acrylic material, a fuel rail, fuel injectors, pressure gauge to monitor the pressure in the system, and supply lines so as to monitor the working of injectors in the engine block using various blends of ethanol fuel.Item Design And Fabrication Of Arecanut Cutter And Sprayer(2015-12-23T13:55:03Z) Arjun, H A; Dasarath Nagaraj, K; Manish; Bopanna, NBThe development of any country depends on how good is the management of agricultural resources and services provided to the farmers. As we all know that a farmer is the backbone of our country and plays a major role in development of our Nation. One should always think and try to provide best services to the farmers and ease their work. Our Project mainly includes Mechanical equipment which can be used to cut the arecanut from the tree easily and reduce the work load of the farmers. We have also taken care of the safety issues involved and have tried best to avoid the same. As many accidents have occurred and there always remains a chance of accidents if a person climbs a tree without safety we have come up with an idea and have fabricated a prototype of the same. As it is completely mechanical equipment and does not involve any aspects of electrical or robotics, this overcomes many drawbacks of the previous designs. Our project is portable and there is no need of any skilled labors to operate it. Our main aim in project is ease the work of the farmers and provide them an economical device and also to help the society with our knowledge.Item Generation Of Unconventional Compressed Air In Trucks(2015-12-23T13:48:06Z) Naresh Kumar, N J; Ankur, Rohilla; Nitin, R; Venkat, KrishnaFuel consumption has been a core consideration since the beginning of the transportation era. These are reasons related to our environment, and to economics. In the competitive truck industry fuel consumption is an important sales argument, since customers on an average drive their trucks for distances of 150,000 km per year, which means that fuel becomes a large part of the lifetime cost for a vehicle. Existing braking system design in commercial vehicles are basically air-assisted, which utilizes the compressed air from reservoir, which is being replenished based on requirement by a positive displacement compressor, generally driven directly by vehicle power pack. In this Project, an effort has been made to partially use the energy stored in the springs (induced due to road undulations) for compressed air generation through a single acting positive displacement pump.Item Design Of Auto Drilling Mechanism For Dynamic(2015-12-23T13:34:36Z) Abrar Ahmed, A; Adil Asharaf, K; Aswin John, Cherian; Mahesh, MadhavanUnbalance is the most common source of vibration in machines with rotating parts. Unbalance exists in a rotor when the mass centre axis is different to its running centre axis. Practically all newly machined parts are non-symmetrical due to blow holes in castings, parts fitted off-centre, machined diameters eccentric to the bearing locations etc. An unbalanced rotor, when rotating, wants to revolve around its mass centre axis. Because the bearings restrict this movement, the centrifugal force due to the unbalance causes the rotor to vibrate. This vibration causes wear to the bearings, creates unnecessary noise and in extreme cases disintegration of the rotor itself can be experienced. It is therefore necessary to reduce the unbalance to an acceptable limit. The aim of rotor balancing is to achieve satisfactory running when installed on site. To identify the position and amount of unbalance, balancing machines are used to correct any unbalance that exists. To correct the unbalance material removal by drilling is preferred. After measuring the unbalance, the software calculates the depth of cut that the machine must drill in order to compensate the unbalance. The balancing machine indicates the operator how much material to remove from each lobe (claw) of the rotor. The operator does not have to calculate or vector this amount himself. Based on the specifications, the balancing machine will display the amount to be removed from each lobe of the rotor. The main objective of the present work is to develop and implement a mechanism to drill the holes automatically by using limit switches and timer pulley arrangement so that the drill depth is accurate and the operator can successively operate three machines instead of one thereby reducing the cycle time for balancing operation. This increases the production rate, reduces rework and increases the profit to the company. In the current scenario, the operator manually places the rotor on to the drilling machine and adjusts the depth of cut as specified on the balancing machine using the scale provided on the drilling machine operated by a timer pulley arrangement. A hole is drilled on the lobe where unbalance exists and the operator continues the same until the required depth is achieved. Therefore by automating the drilling operation, an accurate drilling is obtained in addition to the benefits of reduced rework and cycle time for each operation, which ultimately leads to an increase in the production rate.Item Design And Static Analysis Of Go Kart Chassis(2015-12-23T13:15:07Z) Sachin, S; Sai Kirthan, Rao; Pradeep, BThe purpose of this project is to design, model and analyse a Go- kart chassis which is rigid enough to withstand various loads during static and dynamic conditions with good performance characteristics.The Go- kart is a recreational vehicle which is used for racing. It is a low level 4 wheeled racing purpose vehicles driven by racing enthusiasts. It is driven by people of all ages and there is no restriction for age as in other racing sports like Formula one. Go- Kart is a vehicle with no suspension and less ground clearance. It was introduced in India in 2003 by MRF. One of the fundamental parts of Go-kart is the chassis. The chassis houses different parts of the go-kart. The design of the chassis has different steps which includes, the theoretical calculation i.e. determining the centre of gravity for the required track width and wheel base. Various chassis is modeled and comparative analysis is done for different conditions such as static loading, front impact, rear impact, side impact and material analysis. The analysis is performed to each and every chassis that are modeled. Based on the analysis results, the chassis with optimum results is selected. The optimum chassis from analysis is further checked for suitable material and the cross section of the material that is to be used to build the chassis. The main parts of a Go- kart are chassis, engine, steering, transmission, tyres and brakes. For a good performance Go- kart the parts mentioned need to be designed effectively. After design and analysis calculations were performed on steering to obtain the Ackermann steering geometry for effective steering. Out of the six different chassis modeled, the chassis 4 is selected as the optimum model. The material analysis shows that the material suitable for the chassis is steel since it has least deformation value. Also from the weight aspect the circular cross section has been chosen over the square cross section as the former is lighter compared to the latter.Item Solar Still(2015-12-23T13:08:42Z) Santhosh Kumar, G; Thilak Raj, S; Yathish Babu, R; Vaishak SB, ReddyThe purpose of this project is to design a water distillation system that can purify water from nearly any source, a system that is relatively cheap, portable, and depends only on renewable solar energy. Distillation is one of many processes that can be used for water purification. This requires an energy input as heat, electricity and solar radiation can be the source of energy. When Solar energy is used for this purpose, it is known as Solar water Distillation. Solar Distillation is an attractive process to produce portable water using free of cost solar energy. This energy is used directly for evaporating water inside a device usually termed a “Solar Still”. Solar stills are used in cases where rain, piped, or well water is impractical, such as in remote homes or during power outages. Different versions of a still are used to desalinate seawater, in desert survival kits and for home water Purification. For people concerned about the quality of their municipally-supplied drinking water and unhappy with other methods of additional purification available to them, solar distillation of tap water or brackish groundwater can be a pleasant, energy- efficient option. Solar Distillation is an attractive alternative because of its simple technology, non-requirement of highly skilled labor for maintenance work and low energy consumption. The use of solar thermal energy in seawater desalination applications has so far been restricted to small-scale systems in rural areas. The reason for this has mainly been explained by the relatively low productivity rate compared to the high capital cost. However, the coming shortage in fossil fuel supply and the growing need for fresh water in order to support increasing water and irrigation needs, have motivated further development of water desalination and purification by renewable energies. Our project goal is to efficiently produce clean drinkable water from solar energy conversion.Item Dynamic Analysis Of Go Kart Chassis(2015-12-23T13:05:14Z) Rakshath, Kulkarni; Rakshith, MC; Sujith, RGo-kart is recreational vehicles which are used for racing and entertainment purpose. Go kart is a small four wheeled vehicle with no suspension and low ground clearance. Go-karts come in all shapes and forms, which are light weight and propelled by small engines to reach high speeds. Go-kart has become more and more popular sport in present days. Go- karting is one of the safest, cheapest and best avenue into motorsports for racing enthusiast. The aim of this project is to design and perform dynamic analysis such as front impact, side impact, rear impact, modal analysis and crash test on go-kart chassis. The chassis should be able to withstand dynamic loading condition. In the present study, in order to arrive at a full functional go-kart there are various stages among which we are concentrating on the dynamic Analysis of the backbone of Go-kart that is the chassis. The performance of a Go-kart depends a lot on the chassis design. A good chassis needs to be able to flex and twist. The design of the chassis has its own sub steps like the theoretical calculation and the data acquired by reverse engineering from the industrial chassis and arrive at various designs. The next step after design is to determine which material to be used. The dynamic analysis is done for best chassis as obtained from static results. Dynamic analysis includes front impact, side impact, rear impact, modal and crash analysis. The best optimum chassis from analysis is further checked for the availability of the raw material and the cost of the build is determined. As the dynamic results are obtained and analyzed, fabrication is carried out. The dynamic analysis of go- kart chassis is carried using ANSYS 14 software. The maximum deformation and stress which act on the chassis in all the dynamic analysis is well under the maximum allowable stress of mild steel and has achieved desirable factor of safety as well.Item Design And Fabrication Of Pneumatic Hammer(2015-12-23T13:01:40Z) Rajesh Kumar, Singh; Raghav, Phaiju; Kabindra Kumar, Sah; Sudip, AdhikariHere we have fabricated the pneumatic forging machine, it's a new innovative concept. Forging is the term for shaping metal by using localized compressive forces. Cold forging is done at room temperature or near room temperature. Hot forging is done at a high temperature, which makes metal easier to shape and less likely to fracture. Warm forging is done at intermediate temperature between room temperature and hot forging temperatures. This machine has been mainly developed for metal forming to the required shape and size. In this machine we have using the pneumatic cylinder for forging the specimen. Pneumatic is air operated device. By doing the manual process it consumes more time and large amount of man power required for forging. By using this machine we can save the time and man power requirement in the industries.Item Comparitive Study, Fabrication And Testing Of Insulation Bricks(2015-12-23T12:57:33Z) Abhilash Thakur, M; Akhil, Rajendran; Melvin, Mathew; Sri Vishnu, RThe present study deals with the Comparison, Fabrication and Testing of Insulation bricks. Rice husk is used as an additive along with raw materials such as Kyanite and Bikaner clay. The use of rice husk decreases the Thermal Conductivity of the brick thereby increasing its application in high temperature refractories. When the rice husk burns, it opens the pores in the insulation brick. Thus, the apparent porosity of the insulation brick increases with addition of rice husk. Also the mass of the bricks reduces. Therefore the Bulk Density decreases. The Cold Compression Strength reduces as the porosity of the bricks increases. This is due to the inability of the brick to withstand a greater load at higher temperature. The Permanent Linear Change of the insulation brick reduces. Insulation bricks usually shrink when heated. By adding rice husk in adequate proportions, the shrinkage is seen to considerably lessened. The Pyrometric Cone Equivalent is a test done to check the temperature at which the material softens. Therefore it determines the softening temperature of the material. The higher the Pyrometric cone equivalent value, the better is the heat resistance offered by the material. Finally, the Thermal conductivity of the material reduces. This increases the insulation property of the brick which makes it suitable to be used in high temperature applications.
