The aim of the project is to create a flexible engine that can run on gasoline as well as steam, just by the change of the camshaft and cam-drive gear modification.

Since this project mainly focuses on utilising the scrap IC engine conversion to steam powered double acting engine, lubrication and other fuel injection complexities can be avoided in steam engine.

From this work estimated power up to 5kW will be generated.

The valve timing of engine is different in 4 stroke & 2 stroke. To rectify this we first analyzed the firing order of the engine. The firing order came out to be 1-3-4-2.
For working of double acting steam engine, any 2 pistons should move in ...

Fast build of relatively simple three dimensional “green” parts is achieved by stacking and laminating two dimensional cutouts made from sheets of metal powder bound together by a thermoplastic polymer such that the stack forms the desired three dimensional shape. The “green” assemblies are then sintered to drive off the thermoplastic and consolidate the metal powder to produce a monolithic metal part. Fine detail may be incorporated by adding compatible “green” elements formed from metal powder and thermoplastic binder by methods such as three dimensional printing into the “green” stack that become an integral part of the final sintered part. The concept includes processes in which “green” sheet layers are shaped by means such as hot bending or vacuum ...

Considered the field power system stabilizer (F-PSS), which reacts to change components of vector induction the resulting magnetic field in a gap and change rotor speed of the synchronous generator. For definition the change of internal rotor running-out angle it is possible to use the geometrical parties between components of an induction vector of a resulting magnetic field B in a gap of the synchronous generator, determined in a stator coordinate system X-Y [8]. Axis Y of this coordinate system is directed in a radial direction from a rotor to stator. The direction of axis X is defined by quantity of pair’s poles р of the synchronous generator. As a reaction of active loading determining a rotor movement is ...

The Journey of finalization of object should undergo many mechanical operations such as milling, drilling, Turning, welding, Tapping. So in all these operations different types of fixtures are used for holding work pieces, my designed fixture helped in innovating in a Fabrication of structural members of an ATV. The total journey of any designed component or assembly completed with help of fixtures only these are the minute things when compared with the component but they play a very vital role in fabrication with Precised accuracy.

To reduce the time conception for clamping structural member's at 360 degrees while fabrication.
To increase the effectiveness dimensional accuracy in fabrication.

ADVANTAGES:
– The prime one is holding the independent members to our ...

When making a panel of carbon fiber, as a general rule to finish the process, these panels have excess measures or need special operations of numerical control. These operations are performed with a numerical control (NC) machine. In these NC machines it is necessary to fasten the panel in a suitable way to machine it. There are two ways to fasten the panel in the NC machine, with vacuun tools or with flexilble table.

* Vacuum tools:
Is a machined part with the shape of the piece. On the surface this tool has been machined a few slots to create the vacuum.

Advantage:
-The tool can be used in any numerical control machine, since the tool is independent of ...

Many villages of India are flooded at rainy season. Water pollution from sinking of toilet occurs. Many diseases are create and it creates plague. The Ganges and others rivers are polluted for it. Except it, place of leaving excreta is another problem.

To save Ganges & people from it I have thought of an innovation idea. The project ‘Floatable Bio-Toilet’ (FBT) may be a successful way in rural areas to protect above said problem.

For this system bio-toilet of durable metal or fiber sheet is to be installed at separate places. Digester tank of this toilet (6x4x4 ft / 5x4x4 ft) to be install on a structure, which will be made by some two side closed & hollow metal pipe, ...

Gear and Teeth for On-site Repair (GATOR)

Plastic Gears and Additive Manufacturing Background
Gears are among the most important and commonly used elements across a range of mechanical applications. Recently, composite plastic gearing has seen an increase in usage for a variety of applications because of its low cost, weight, and its ability to satisfy mechanical requirements of gearbox or power transmissions. During gear use, large forces are produced at the base of the gear teeth, resulting in wear and degradation. In fact, more than 85% of gear failures are associated directly with teeth disintegration. Because plastic gears are currently manufactured via conventional molding and machining processes, the entire gear must be replaced when even a single tooth fails. As ...

It consist of 6 parts:
1.Base
2.Tool guider
3.Cutting tool
4.Feed controller
5.Shaft
6.Gear

First, we place a blank under the base which coincides with the base and move the cutting tool near to the edge of the blank. The base reciprocate up and down to a limit of gear depth. Due to reciprocation the tool start cutting teeth.
To give feed the feed
4. Controller is rotate as per the feed requirement.
due to that the gear which is coupled to shaft start rotating and it rotate the disc.
5. Due to square thread mechanism(between disc and tool guider) the tool guider start moving and give feed the the gear.
6. After cutting a ...

ROLE OF OUR MACHINE:

The high amount of labor necessary for weeding, harvesting, drying, threshing and shelling makes the crop economically unattractive to the younger generation of farmers. The very laborious tasks of threshing and shelling are made easier with our groundnut separator and decorticator machine. The areas where our machine sounds helpful are as follows:

INSIGHT OF THE MACHINE:
A rectangular frame is made with 5mm thick mild steel with a total height of 4 1/2 feet to which two cross bars are welded throughout the length. To the first cross bar, a shaft of 25mm are made to rotate on two Plummer blocks across the span of the machine. A hollow drum of 150 ...

Two-stroke engines have two important advantages over four-stroke engines: They are simpler and lighter, and they produce about twice as much power. So why do cars and trucks use four-stroke engines? There are four main reasons:

• Two-stroke engines don't last nearly as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear a lot faster.
• Two-stroke oil is expensive, and you need about 4 ounces of it per gallon of gas. You would burn about a gallon of oil every 1,000 miles if you used a two-stroke engine in a car.
• Two-stroke engines do not use fuel efficiently, so you would get fewer miles per ...
