A Comprehensive Study on the effects of Nano-additive on CI engine with diesel with bio-Diesel Blends
(NHCE, 2024) Mithun S Gowda 1NH20ME073 Kishore Kumar V 1NH20ME056 Vishal C Reddy INH20ME118 M Gautham INH20ME065
This study examines how nano additives affect the operation, combustion, and emission properties of diesel and biodiesel blend-fuelled compression ignition (CI) engines. It is essential to incorporate biodiesel into fuel systems to address environmental concerns and the depletion of fossil fuels because it offers a sustainable substitute for conventional diesel. Improvements are necessary, though, because biodiesel performs worse and emits more certain pollutants. Because of their large surface area and catalytic qualities, nano additives may enhance the characteristics of fuel. Experimental investigations are conducted using a single-cylinder CI engine under different operating conditions, including various load levels and engine speeds. Comprehensive analysis techniques such as combustion pressure analysis, exhaust gas analysis, and engine performance measurements are employed to evaluate the effects of nano-additives on engine combustion and emissions characteristics.
Advanced Driver Machine Interface for Locomotives
(2020-09-21T06:19:25Z) Rohit Kumar, Singh; Shalini, Koyikkal; Harsh, Srivastava
An advanced driver machine interface for locomotives for the benefit of the customer to have a standard interface to be followed for DMI uniformity across major railway systems. The Driver Machine Interface will act not only as an interface for locomotive drivers, but also as a point of contact between the driver and the railway signaling system. The objective of this communication consists in the evaluation of the performances of a system in the presence of failures, because today we note an evolution from the classic referential of Dependability (evaluation of probabilistic indicators for a given mission, each mission evaluated corresponding to a set of very specific performance levels) towards a benchmark of Performance Engineering. In fact, in the classic approach to Dependability, the mission levels chosen arbitrarily (maximum mission profiles, critical) among the set of possible trajectories of the system, lead to decision-making in the design process based on partial considerations. However, today, an industrialist must be able to commit to the achievement of performance, the specification of which includes all the hazards likely to be encountered during the operational life cycle of the system.

(2019-07-05T07:48:33Z) ADARSH, K; ANAND, SASIDHARAN; ARUN, RADHAKRISHNAN; K J, THRISSUL
On constant hunt for performance oriented cars, aerodynamics of cars is an important research topic that cannot be neglected as it plays a pivotal role in stability, handling and fuel efficiency. The scope of the project is to gain insight into the phenomenon that occurs during the interaction between the fluid that is air and the car as the latter propels itself forward. We have simulated real world conditions for original and modified models of the car in an attempt to reduce the overall drag coefficient of the car. The use of fluid flow simulations (using FLOEFD CFD tool) in such a CAD-embedded context is obviously very attractive as it can not only accelerate the design process, but it can make these processes more predictable and reliable, against a background of increasing design complexity and dependence on external development partners.Aerodynamics is something that changes not only how fast a vehicle goes, but also how efficient it is.

AI DRIVEN TOOL WEAR AND PRODUCT QUALITY MONITORING SYSTEM USING IoT
(2025-05-06) SATISH; TARUN N; V M KHESHAV; SHIVA KUMAR P
Lathe machining is a popular production technique where a fixed cutting tool shapes a revolving workpiece. Manufacturing cylindrical components like shafts, gears, and rods, which are vital in many different industries requires this procedure. The state of the cutting tool, which wears down and becomes blunt over time from constant contact with the workpiece, has a significant impact on the effectiveness and calibre of lathe machining. Reduced machining performance from this tool wear results in dimensional errors, poor surface finishes, and most importantly long downtime, all of which raise operating expenses. Early tool wear detection is crucial to preventing these detrimental effects. Visual inspections and trial-and-error testing are two time-consuming and sometimes inaccurate traditional techniques of checking tool condition. In order to promptly identify tool failure or bluntness, there is a rising demand for more effective, real-time, and data-driven methods. Using sound decibel sensors, which can record the noise produced throughout the cutting process, is one viable alternative. Since variations in sound levels are frequently associated with tool wear, these sensors can offer important information on the state of the cutting tool. The goal of this research is to create a prediction model that uses sound decibel data to estimate the bluntness or failure of cutting tools in lathe machines. Decibel sensors will be positioned close to the tool post to record and evaluate sound levels in real time, allowing for the tracking of the tool's condition. A variety of cutting variables, including feed rate, cutting speed, and the materials of the tool and workpiece, will be included in the data that is gathered. Regression models will be created using statistical analysis tools like Minitab in order to forecast bluntness or tool failure based on the sound data and additional cutting characteristics. By facilitating preventive tool maintenance and reducing expensive downtimes, this predictive model seeks to improve machining productivity and eventually contribute to more economical and environmentally friendly production processes.

Automated Rubber Tapping Machine
(2018-06-23T10:14:38Z) Sagar, K; Sreesh S, Krishna; Sushreeth, Puthran; Syed, Anies
Rubber tapping is the process of extraction of latex from rubber trees. Rubber tree tapping is considered to be a skill oriented job. During the tapping process, the taper has to make a downward half spiral incision on the tree bark to extract the white milky liquid called latex. On a typical day, a rubber tapper has to tap about 500 to 800 rubber trees manually with a tapping tool within a specified time of the day. Availability of skilled laborers who could accomplish this mammoth task is getting scarce as days pass by. Even though cheap unskilled labor is available, without appropriate time and training they would end up damaging the tree. The automated rubber tapering machine designed here would replace the manual labor required for the tapping process. Also with a clock feature to control the timing of the tapping process, higher yield of rubber latex could be obtained.

Carbon Di Oxide And Vapors Of Olive Oil Powered Solar Cooker
(2015-12-23T11:43:32Z) Hemanth, L; Girish H, R; Rakshan, Padiyar; Channagiri K, Dalal
Today, due to the increase in cost of living, people are finding alternate means to generate energy. Non-conventional sources of energy such as solar, wind and geothermal energy are being harnessed to meet the increase in demand and cost. As we live in a tropical region, solar energy is reliable and available in abundance. A solar cooker is a simple device that utilizes the heat energy obtained in form of thermal radiation form sun to cooks the food, boils water and also can be used for sterilizing instruments. Solar cooker has seen its existence as late as 1700’s. Solar cooker has seen its dominance mainly in developing and emerging countries especially in India. In order to overcome the issues with the existing solar cooker technology, we have developed a prototype to elevate the temperature, thereby increasing the heating efficiency within the cooking chamber. Cooking chamber is enclose within a glass box expect for the side available to be opened to place food/water inside the container. The glass box and cooking chamber are well sealed so as to not allow the carbon dioxide into the cooking space. A small opening is provide in the glass box fitted with a cork, which acts as an inlet and outlet port to allow the space within the glass box to be filled with carbon dioxide. Cooking takes place in a solar box cooker based on the principle, the black absorbing material coated inside the walls of the cooking chamber absorbs direct thermal radiation from the sun converting it to heat energy. In general, sunlight both direct and reflected enters the solar box through the glass, the entered light is scattered by the green house gases mainly water vapour present within the container who’s wavelength increases. It turns to heat energy when it is absorbed by the dark absorber plate and cooking pots. This heat input causes the temperature inside of the solar box cooker to rise until the heat loss of the cooker is equal to the solar heat gain. Temperature obtained is sufficient to cook food and pasteurize water.
