The novelty of agriculture is unavoidable to have the food needs of the increasing population and quick industrialization. The project describes the mechanization that allows the preservation of inputs to ensure the good distribution, decreasing quantity requirement for good response and avoiding wastage of inputs used. Mechanization decreases the unit cost of production by input preservation and larger productivity.

The issues increase because of the workers that are not enough in farmlands. Therefore, majority of the fields are found uncultivated. The poor farmers are unable to bear the large cost of power tillers present in the market. Many poor farmers possess small land and cannot afford to buy a tiller to fulfill their requirement due to uneconomical. The cost of tillers is very expensive present in the market and its working is also very complex and could be function by skilled men only.

 The garden tiller is a tiller which works on diesel and utilizes efficiently to cultivate ginger, tapioca, pulses etc. and it is affordable by middle class farmers. The objective of this project is to manufacture and design a tiller depending on diesel which is simple to function with affordable cost.

 The design of the garden tiller was successfully manufactured which found to function depending on the needs. The garden tiller designed is utilized for various actions consisting cultivation of turmeric, tapioca, pulses ginger etc. The cost of the garden tiller is nearly Rs.25000.

Conclusion:

Therefore the machines in this Project on DESIGN FABRICATION AND PERFORMANCE EVALUATION OF GARDEN TILLER developed can be utilized by middle class farmers and who are suffered from deep problems because of unavailability of enough labor to work in farmland. Thus this multipurpose project can be beneficial for the small scale farmers.

The main aim of this PROJECT REPORT ON DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM is Cryogenics.

Cryogenics is the study of low temperature which means the entire phenomenon locates below -150°C or 123K. Cryogenic engineering is the design and development of systems and components to maintain, produce, or utilize low temperatures. The systems produce the refrigeration power at low temperature.

There is a strong requirement of cryocoolers for many applications. Infrared detectors, thermal imagers and night vision devices require form of cryogenic cooling for military purpose. The chips of semiconductors cryogenic cooling in the electronics improve the performance drastically to reduce the thermal noises. These are important part of the ultra clean high vacuum cryopumps utilized for high reliability in the manufacturing of semiconductors.

Cryocoolers are required for cryogenic surgery and conservation in the areas of medicine and cryobiology. These are very reasonable price, flexible in all weather conditions and high security is the important factor. Cryogenic temperatures are maintained and achieved with one or more refrigerating units called cryocoolers.

The Mechanical Final Year Project Report is about the system to freeze for many applications. The kind of cooling is utilized to store fruits but unfit for fish industries. Further, there are many reasonable vegetative microorganisms discovered in food which have decreased by refrigeration when high freezing is utilized. The common freezers are unable to manage with great rate of cooling. The challenge of rapid freezing has increased efficient storage with the progress of plate freezer.

The plate kind evaporators are employed in banks or in single. The plates possibly manifold to pass the refrigerant parallel or connected for flow in the serial way. Plate evaporators are beneficial for the purpose of liquid freezing installation.

This Design & Fabrication of Plate Freezer project is about the plate freezer designed with two plates linked in parallel with freezing load of 0.335 KW. The tube is installed among two metal plates and plates are brazed together at the border which results in plate surface evaporators.

The common food protection is done by storing the food in the chambers possessing the evaporator coils surrounding it. The chamber is insulated with casing around it. The heat from the food to the chamber surface is transferred through the air space. The freezing rate takes lot of time and is low because of the fact that air is a bad conductor of heat. The freezing rate is incremented with the freezer.

Today, pollution is a major danger to the Environment. Vehicular exhaust is responsible for the pollution. PLASMATRON fuel converter technology is the new technique that reduces the concentration levels of emissions.

Engineers have added hydrogen to gasoline to make an engine run cleaner and efficiently. It is suitable for fuel pretreatment and for exhaust after-treatment applications. The Emission control methods are Fuel pre-treatment and Exhaust after-treatment. The Plasmatron fuel converters are Thermal type and Low current type.

This EMISSIONS REDUCTION USING HYDROGEN FROM PLASMATRON FUEL CONVERTERS project describes a block diagram of Diesel Engine Emissions Aftertreatment Concept which is explained in two ways, normal operation and regeneration. In normal operation, the oxygen rich is exhausted from engine which is absorbed by the catalyst and that cleans the exhaust. But in regeneration, there is a plasmatron reformer which is a diesel fuel. It is rich with hydrogen gas to have clean exhaust.

The energy given by the plasma facilitates partial oxidation reactions with negligible soot production. Under ideal stoichiometric conditions, the partial oxidation reaction is given by CnHm + n/2 O2 nCO +m/2 H2. It gives continuous ignition at the entrance of the fuel in the gasification of fuel.

 It increases gasoline engine efficiency by 20 to 25%. It potentially reduces U.S. oil imports by 1.5 million barrels per day. It also reduces diesel engine which exhaust emissions by 90%. It needs modest engine modifications with no major redesign of the vehicle.

Conclusion:

This project concludes about the pollution which is a major threat to the Environment today. So PLASMATRON fuel technology decreases the concentration levels of the emissions.

The two stroke engine completes its cycle of operation in one revolution of the crankshaft or two strokes of the piston. The intake and exhaust processes of four stroke engine are look after by the incoming fresh charge. It is compressed in the crank case or by means of a separate blower whereas the engine piston is present near the bottom dead centre. The engine piston compresses the fresh charge and expands the product of combustion.

The mechanical construction is simplified with the help of the piston in two stroke engines as a slide valve in conjunction. It is along with intake and exhaust ports to cuts of the cylinder side.

 The petrol engine works on two strokes. The first one is Stroke 1A, Piston BDC (Bottom Dead Centre is at the lowest point within the cylinder. The air, petrol, and oil mixture is forced into the cylinder and exhaust gases are made to drive out. The second one is Stroke 1B where the piston moves upwards to cover the air intake and exhaust ports closing them.

The engine ignites fuel in the upward stroke and hence there are two strokes for ignition of fuel and they are known as upward and downward stroke. If the piston moves in upward direction from down to top in the first stroke then the air and fuel mixture compressed and ignited with a spark plug where as upward stroke comes to end.

Thermocouples device is mounted on different fields of the engine that measures stroke temperatures. Engine speed indicator measures the number of revolution per minute of the engine shaft. It is done with the help of a speed sensor displayed in the digital indicator.

Conclusion:

This Mech Project & PPT on DESIGN AND ANALYSIS OF A TWO STROKE PETROL ENGINE TEST RIG Mechanical project is built up for laboratory purpose to check the performance of two stroke petrol engines at environmental conditions.
