Introduction to BIODIESEL IN DIESEL ENGINES:

Bio diesel is a vegetable oil that is a clean burning diesel fuel and is obtained from soya bean and other vegetative oils. It is typically processed by the chemical reaction of lipids with alcohol and this process is called as esterification. The Mechanical Engineering Project “ Bio diesel in Diesel Engines Latest Mechanical Project” has been presented because it is a good replacement for conventional fuels and is equipped with environmental benefits.

Bio diesel is mainly used in diesel engines as they improve the engine’s combustion performance and better engine lubrication along with reduction in air and water pollution. The most critical aspects of bio diesel use and their consequence are studied and presented. Also techniques for the optimum bio diesel are suggested. Engine conversions are not requires unless the engine has old fault lines.

Description:

Additives are made in large quantities and mixed with engine fuels to increase the performance of the engine. These additives serve as catalyst because the help in combustion and control the fuel quality during distribution. It has been experimentally found that the thermal efficiency for bio diesel and its blends are higher than the mineral diesel. These additives are Multi-DM-32 additives with methyl ester.

The resistance of the engine and the resulting overcoming of the durability test are the two major issues that have to be taken into consideration in the spectrum of power consumption and production of bio diesel in connection with assuring and guaranteeing the appropriate use of methyl ester. This project gives suggested solutions too.

Biodiesel in Diesel Engines Conclusion:

As an alternate for fossil fuels, Bio diesel is the best solution. It should be the serving mechanism for reducing and maintaining the price of automobile fuel. India has vast amounts of resources for producing Bio diesel; research is being carried out to convert the vegetable oils in to bio diesel. Bio diesel can especially provide a boost to the rural economy.

The piezoelectric effect was discovered way back in 1880 by Pierre and Paul-Jacques Curie. They found out that when certain types of crystals say for example quartz or tourmaline were compressed in the direction of a certain axis, it produced a corresponding voltage at the surface of the crystal. This is what is termed as the piezoelectric effect.

     The piezoelectric effect is an important discovery. It is applied in a lot of practical devices. This paper is thus a “Piezoelectric Car Mechanical Project Idea” which makes use of the piezoelectric effect in designing the car. Besides this, the piezoelectric effect is implemented in microphones, wave filters etc. The reverse effect can also be obtained i.e. when an emf is applied, it produces mechanical vibration.

Description:

       In this paper Project on piezoelectric car the car’s tyres are made up of piezoelectric materials. The tires in this kind of car are made up of piezoelectric cables which in turn are made up of piezoelectric generators. When the tyres move on the road continuous pressure is applied on the tyres. This generates electricity as per the piezoelectric principle.

        The piezoelectric generator used in the car is a piezoelectric crystal which is in between two electrodes that are metallic in nature. Thus according to the piezoelectric effect, when mechanical stress is applied, the emf is generated.

Piezoelectric Car Conclusion:

      Thus by knowledge of the piezoelectric effect, the required piezoelectric car is designed. The electricity generated by the cables in the tyre is used to feed the batteries that power up the car. This makes the batteries self-charging in nature and external charging is required for the very first time. This system is also eco-friendly in nature and does not cause any pollution the environment. If Lead Zirconate piezocrystal is used then a generation of 100000 volts is obtained by deformation of tire.

Introduction:

           In this Mechanical project “Plasma Arc Welding and Machining Project Reports” is explained. Plasma arc welding (PAW) is the process of joining metals that are produced by heating using a constricted arc placed between an electrode and work piece. Plasma arc machining (PAM) uses a high-jet and high-temperature jet of gas to melt substances in its pathway.

        The plasma welding process was used in the year 1964 and has brought better control to arc welding process. Plasma preserves its original advantages and gives an advanced control to produce long electrodes for higher productivity. Plasma process can be performed manually as well as automatically. It’s been utilized for precision welding of surgical instruments and also to the welding of kitchen equipments.

Operation:

        In this project Plasma arc welding and machining for welding purposes the plasma is heated to a very high temperature and then ionized for electrical conduction. This plasma gas is forced and arc through an orifice and the metal to be welded is melted. This high temperature of plasma provides an increased heat transfer rate and results in high welding speeds and deep welding depth.

       PAM is a process of thermal cutting that uses a narrow beam of high-temperature plasma that is used to melt and separate the metal. The arc is formed in between a negative electrode and the workpiece which is positively charged. The metal is melted from the heat derived by the transferred arc and the high-velocity jet removes the molten matter from the cut. This is used for extremely thin welding.

Conclusion:

This project has been highly successful in lot of applications like the automatic repair of jet engine blades. However due to the expense involved in using this process, it is not preferred generally.  But, there are still a lot of changes which could be done to make this process a cost-viable option.

Introduction to the BE Mechanical Project:

            In earlier days, planers and shapers were popularly used but have been rendered obsolete now. The milling machines have superseded them as the best machine tools since the speed of metal removal is quantitative in nature. This project “Planer Milling Machine Accommodated With Drill Head” explains about milling machines. These machines are of two kinds: double housing and open-side.

          In the double-housing, vertical supports are present on both sides of the long bed whereas in the open-side arrangement, vertical supports are only on one side thereby permitting the work piece to extend beyond. Using mailing machines increases the production rate. Since the drilling and planar surface machine is incorporated in one unit, power is saved and there is no transfer of tones between machines.

Working:

     In this project Plane milling machine, the work piece is lifted and hoisted in position on the machine bed. It is then secured in the holding fixture with the aid of wrenches and position is verified using gauges or calipers. The machine is then started and automatically operations are done and if tools have to be changed then the machine is stopped and tool changes are made. Then the machine is started again.

         If the work table or machine table has to be leveled, it can be done by using a long flexible liquid column which is a simpler technique. Leveling of work tables is not difficult and can be achieved by using spirit levels or other techniques. In this project, the drilling head is fixed to the lead screw of the arm using half-nut arrangement and this saves time and power.

Conclusion:

    This project is very advantageous as maintenance of the entire unit is simple and it is also a cheap process. For leveling of the work table, skilled workers aren’t required. The work tableset up time is considerably reduced and lengthier tables can be leveled with application of less effort.

Introduction to the B tech Mechanical Project:

           An acoustic enclosure is defined as a containerized vessel for housing generators. This Mechanical Engineering Project Optimum Design of an Acoustic Enclosure for Diesel Generator is aimed at designing acoustic enclosure that can reduce noise levels and increase the reliability and durability of generator sets. It also easily serviceable and offers better working conditions.

         This enclosure is used to prevent sound from escaping. The enclosure is installed on the site around the fixed generator. They can be used as a single unit and to optimize appropriate lifting points along with selection of proper beams and columns. Air ventilation is necessary in an enclosure to remove exhausts, providing clean air for combustion.

Description:

           In this project, Optimum design of an acoustic enclosure for diesel generator as air comes in through the enclosure, the temperature increases. The temperature difference is the variation between alternator and outdoor. Cross ventilation and flow of fresh air is mandatory for good operation of genset allowing air flow from alternator to engine end. Thus inlet and outlet openings are incorporated without compromising soundproofing.

       To design an opening that allows air to pass through with minimum entry of foreign particles a ventilation product called louver is used. Any obstruction in the air flow gives rise to resistance reducing the velocity. Thus, for proper enclosure ventilation is to choose louver dimensions by making note of company standards, louver considerations and prescribed static pressure.

Conclusion:

       This project is easy to use and considers the frequency range. However accuracy is less as only transmission losses are taken into account and not insertion losses. An optimization in the code for an acoustic enclosure. Optimal weld thickness can be used and application of computational fluid dynamics of flow through the acoustic enclosure. An additional sound reduction of 10 dB can be realized through insertion loss phenomenon.
