The An Innovation in Automotive Industry Six Stroke Engine designs a Beare Head,a new type of Six-Stroke Engine head design  which has an improved method for combustion process  to meet the  demads for low emissions and low fuel consumption in modern combustion engines.

There is just one common feature in majority of the actual internal combustion engines, operating on different cycles which is combustion occurring in the cylinder after each compression, resulting in gas expansion that acts directly on the piston (work) and limited to 180 degrees of crankshaft angle. According to its mechanical design, the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating combustion engine. However, The four-stroke block, piston and crankshaft remain unaltered. This combination of two stroke and four-stroke technology has given the technology its name the “six stroke engine”.

The Six Stroke designed in this project is thermodynamically more efficient because the change in volume of the power stroke is greater than the intake stroke and the compression stroke. The main advantages of six stroke engine includes reduction in fuel consumption by 40% and its adoption by the automobile industry which would likely have a tremendous impact on the environment and world economy.

ADVANTAGES:

• Thermodynamically more efficient.
• Reduction in fuel consumption by at least 40%.
• Two expansions (work) in six strokes.
• Dramatic reduction in pollution.
• Multifuel.

CONCLUSION:

The 6 Stroke Engine designed in this project is a solution for the replacement of the internal combustion engine which not only is an improvement of  the current technology,but  is within reasonable time and financial limits. And when allied with the so-responsive pickup and a wide spread of usable power with a bike, it makes the bike ridiculously easy to ride, hardly using the gearbox.

In this Vehicle Dynamics Mathematical Analysis of Hydro pneumatic Suspension Systems, a Mathematical model of the HYDROPNEUMATIC spring stiffness behaviour is developed for Vehicle Dynamics.

Vehicles used for transport of loads have their efforts on the axles very close to the allowed or critical limits mainly during its travel on a bumpy surface or during cornering. In such cases the use of conventional suspension systems can increase the axle’s overload phenomena. Hydropneumatic suspension leads to an even distribution of load per axle, thereby decreasing the overload problem and simultaneously increasing the efficiency and comfort levels.

This project studies the various factors or parameters that influence the spring stiffness behaviour and has mathematically found them.Even a methodology for primary specification of critical parameters of a hydropneumatic suspension system is presented.

CONCLUSION:

In this project, the spring stiffness of the Hydropneumatic suspension system has been calculated mathematically and its effects have been thereby stated.. Hopefully, in the future,more and more vehicles using such kind of suspension systems and thereby increase the efficiency of the vehicle and simultaneously increase the ride comfort are expected to be designed.

This Usage of Cad cam Systems for Manufacturing of Solid Relief MAPS designs and studies the usage of CAD/CAM systems for manufacturing of solid relief maps, and presents production of a prototype

Relief maps are generally required for military purposes, land use and town planning works. These maps are generally prepared as solid blocks, and are hand made. Some difficulties and impossibilities due to sharp height differences may be inescapable in thecourse of production of these maps. Hence, 3D Model maps usind CAD CAM systems are used to design and manufacture them.

These maps are usually prepared as solid blocks, and their production are usually done by hand.Therefore, their metric correctness, soundness and production time entirely depends on human factor and the base material being used. During the production of these maps, presentation of very small details such as sharp changes in height may require some exaggerations due to difficulties in cutting,carving and sticking the materials.

CONCLUSION

The releif maps designed in this project, usind CAD CAM system are very useful inresearch work and also for solid model production in architecture and town planning works.

This Tidal Power the Future Wave of Power Generation Btech Seminar emphasizes the possibilities of utilizing the power of the oceans by pollution free, Tidal Power Generation.

Renewable sources of energy are necessary because the Earth will eventually run out of the resources to create non-renewable energy. There are three types of renewable energy sources: solar, wind, and waterpower.  Both solar and wind power are drastically affected by weather variations, while tidal power varies little when the weather changes power.

Tidal power can be the primary form of renewable power utilized. to decrease global dependence on natural resources, Built upon steam turbine knowledge, tidal turbines draw on innovative technology and design to operate on both the inflow and outflow of water through them. tidal power plants are capable of producing reliable and efficient power.

ADVANTAGES.

• Renewable and sustainable resource
• Reduces dependence upon fossil fuels
• Produces no liquid or solid pollution
• Present no difficulty to migrating fish (except tidal fences)
• Shelter the coast, useful in harbor areas or erosion zones
• Resource exists on a worldwide scale from deep ocean waters
• Short time scale between investing in the modular construction and benefiting from the revenue

DISADVANTAGES

• Very expensive to build.
• Affects a very wide area – the environment is changed for many miles upstream&downstream. There are very few suitable sites for tidal power stations
• Many birds rely on the tide uncovering the mud flats so that they can feed.
• Only provides power for around 10 hours each day, when the tide is actually moving in or out.

CONCLUSION

    Tidal power fits the bill, a natural source of energy with many benefits. The planet’s tidal capability greatly exceeds that of the world’s entire coal and oil supply. It is an ideal source of energy with great potential. When developed, tidal power could be a primary provider for our future energy requirements.

This Solar Energy through Solar Space Stations Mechanical Seminar presents a mutual collaboration based SOLAR POWER model to overcome launch cost, which involves three GEO satellites and two earth stations, i.e through Solar Space Stations..

The current primary energy source –fossil fuel threatens global environment by emitting CO2, which is responsible for green house effect global warming, environmental degradation, declining nutrition on land and sea from rising CO2, and rapid decrease of fossil reservoir.

Solar Power from Space (SSP) promises clean and everlasting energy supply for the growth of the mankind.

To overcome these limitations concept of Solar Power from Space is getting momentum, Solar Power from Space is a proposed concept to place a gigantic solar power station in space orbiting around the earth that uses microwave power transmission to beam solar power to a very large antenna on earth where it can be used in place of conventional power sources.

CONCLUSION:

This project has examined the aspects of space-based power for the earth, the significance, the need and possible solutions and finds that space-based power can provide the necessary new source of clean energy for earth in the next century to loosen our dependence on fossil fuels.

In this Smart Materials A view towards Shape Memory Alloy Mech Paper a  comparative study between SMA’s and other generally used materials or alloys is made , with the help of live examples (aircraft maneuverating, robotic muscles and human bone plates),

Smart materials are one among those unique materials, which can change its shape or size simply by adding a little bit of heat, or can change from a liquid to a solid almost instantly when near a magnet. These materials include piezoelectric materials, magneto-rheostatic materials, electro-rheostatic materials, and shape memory alloys (SMA’s).  Shape memory alloys (SMA’s) are metals, which exhibit two very unique properties, pseudo-elasticity (an almost rubber-like flexibility, under-loading), and the shape memory effect (ability to be severely deformed and then return to its original shape simply by heating).

Advantages:

• Biocompatibility.
• Diverse Fields of Application.
• Good Mechanical Properties (strong, corrosion resistant).

Disadvantages:

• Relatively expensive to manufacture
• Have poor fatigue problem
• Cannot survive for more cyles unlike a steel component.

CONCLUSION:

The SMA’s discussed in this project are supposed to have a major say in the field of precision engineering and surgical operations in years to come. The sensing and responding property of these materials make them analogous to human brain and muscular system.

The Ship with Wind Mills Mechanical Engineering Seminar aims at bulding Ship With Wind Mill to use its energyu and generate power out of it at a very economical price.

Wind energy,one of the non-conventional sources of energy  can be utilized to run wind mills to produce electricity. The latest technologies of wind mills say that the offshore wind mills have high out put. This is because offshore is free from obstacles and full of non-stop high speed winds. The power developed by the wind mills is said to be depend on the cube of velocity of air that passes through the turbine. Offshore wind mills have only for the 97% of time, which means the technology is yet to develop to be more efficient.

So problem is not having wind for 100% of time, and the solution to the problem is SHIP WITH WIND MILLS. This is the ship which will carry wind mills into the open sea and add its velocity component to the wind so as to get wind for 100% of time. When calculations are made it is found that this method is generating power such that ,  a fraction off out put is sufficient to run the ship and the left over power can be made use of

CONCLUSION:

The project projects on reaching the high demands of the rapidly developing generation to be as efficient as possible. It gives the way to productively utilize freely available air and generate power out of it.
