The objectives of Fuel Injection in the Compression Ignition Engine Project are to adjust the meter as per the fuel quantity based on the accuracy of engine. It delivers the fuel in multi-cylinder engine. The fuel is injected at the exact time in the cycle. The fuel is injected at the appropriate rate. The fuel is injected with the spray method and enough atomization by the model of the combustion chamber and to give correct penetration. The injection starts and finishes without trickling.

 The fuel should be supplied by particular nozzles to make the appropriate atomization degree in the combustion chamber such that it dissolves with enough air for entire combustion in the available time. The output quantity should be properly monitored in the cylinder of engines to examine the balance b/w the cylinders.

 The injection time and the pressure increment with the size of the engine size. The small direct injection (DI) engines possess 25 degrees crank travel. Engines need to have limited exhausted NOx emissions and require shorter injection time with large injection pressures.

 There are two important systems in fuel-injection systems. They are air injection and solid or airless injection systems. The systems of mechanical, airless,  or solid injection include three kinds. They are individual pump system, distribution system, and common rail system. There are three filters mentioned in this Fuel Injection in the Compression Ignition Engine Project Presentation. They are primary stage, secondary stage, and final stage.

 Conclusion:

 The fuel injection reserves fuel into the engine at appropriate metered in regard to the power needed with full speed and the engine gives exhaust noise, power for fuel consumption, emissions , and smoke.

Electronic Magnetic Forming (EMF) is a process to use electromagnetic forces to produce metal without using a tool or punch that come into contact with the part.  This is also an ideal process for joining mechanically or assembling metal components.  An electromagnetic coil is driven by an electric current in a sharp pulse to generate the force for metal forming.  The product produced by this method is free from toll marks and heat effects since there is no tool or abnormal heat.

 The process is suited best to form techniques on aluminum leave wrinkles on the job like spring back and poor reproducibility. Therefore, EMF process is a potential application in automobile to form sheet metal components.

  The line voltage supply charge the capacitors and the whole circuit is separated from the power source.  The charge stored in the capacitors flows like current through the work coil when the forming circuit switch gets closed. The current forms a strong magnetic field between the coil and the work piece which is called Lenze’s law. EMF is used to attach and assemble components.

 The main components of the machine are The structure, The Die, Hydraulic power-pack and hydraulic circuit, Machine Control Circuit, Electromagnetic coil with accessories, Capacitor, Voltage multiplier circuit for capacitor charging, Capacitor charging circuit, and Capacitor Discharging circuit.

 Conclusion:

 This Electronic Magnetic Forming (EMF) project concludes excellent technique for forming thin metals, good for mechanically joining metals or non-metals. It is quicker, easier, and easy to implement. It is easily automated and product formed is free from any defects and likely rapid growth of EMF machines.

This is a tough Electro Magnetic Crane project and is suitable at 11 or 12 grade level. The students need to interact with DC motor, stepping motor, H-Bridge, an LED, and an electromagnet. The aim is to transfer paperclips from one to another bowl with rotation of 90°.

 The crane begins by moving the up and above the bowls. When the program begins then LED begins to flash. The crane leaves the magnet within the bowl. The magnet gathers the paperclips. The crane transports the paperclips and magnet. It makes 90° rotation.

 It brings the magnet to low position and brings clips within the second bowl. The magnet turns off and generates the paperclips. It transports the magnet back to its position. It moves back in the position of first bowl. The LED switches off if the crane starts moving.

 H-Bridge switches the DC motor in one way and makes the D2 high and D3 low. It switches the DC motor in opposite way and makes D2 low and D3 high. It prevents the motor and makes D2 and D3 low.

 The stepper motors function with transporting the repeating methods of bits to various coils. The Popsicle stick is tapped at the stepper motor with the help of protractor and it is the best method to calculate angle per step.

To create as many coils would result the magnet stronger. Magnet wire performs better since it is light and many coils are present. The soft iron creates the magnet function good.

The finite element depends on the concept utilized to evaluate the influence of thickness of gear rim by tooth bending process in less addendum great spur gears. The gears are utilized in sugar mills, cement plants, coal mills, ball mills, kilns, copper converters, grinding mills, and anode furnaces etc. The concept is improved with ANSYS Parametric Design Language (APDL) to produce 1, 3, and 5 tooth sections of a spur gear.

 The finite element approach is identified in the regions of Highest Point of Single Tooth Contact (HPSTC). The 1, 3 and 5 segments are recognized by different β that is the ratio of thickness of rim of the gear. The influence of mesh can be found in the 3-D models.

 The bending and equivalent stresses are achieved for various β values in many models. The gear tooth and surface of rim stresses are presented in tables with the help of Microsoft Excel and program written in APDL and plots are produced by MATLAB program. Maximum von Mises plots and maximum bending are achieved with different β values in both dimensions models.

 The photoelastic method was broadly utilized since many years. The technique was tested for the stress influencing at the gear fillets. The technique has used to improve the fillet stress which includes unbalance pressure angle. It has developed by using realistic shapes in photoelastic models.

 Conclusion:

 The Effect of Rim Thickness on Bending Stresses in Low Addendum Large Spur Gears conclusion made on working of meshing concept is improved with mapped meshing abilities of ANSYS to produce two and three-dimensional element concepts of the gear. The managed meshing method is used to stop great stresses at load regions and to escape various elements in the low regions and to produce the web in the locations of the gear tooth.

There are many accidents happening with the four wheeler vehicles which are incrementing in our day to day life. The major reason behind such deadly accidents is the cell phone.

When driver utilizes his cell phone while driving, it changes his mind. To get rid of this issue, here we present a new kind of holder of mobile phone which climb the mobile phone and one can need not hold the mobile in hand.

The important approach of this Design of Mobile Phone Holder for Automobile Steering Wheel project is to keep the mobile on the stand on the steering since steering is the placed nearer to the face of driver while driving. Hence the driver is able to attend the call by using loudspeaker mode and without picking the mobile the driver is able to response to the call.

During the manufacturing of this mobile phone holder, there are few limitations such as steering wheel is the rotating component on which the mobile phone holder is joined and as it rotates, the holder also rotates which causes drop out of the phone. To overcome this problem, we have used the concept of bearing and to obtain this concept, stabilization of the inner race of the bearing is compulsory.

Conclusion:

It is very clear from the description that design of mobile holder is very essential part of research that solves various issues with the demand of the customer. Hence to get the solution for these problems, we have accepted to prosper new kind of the mobile phone holder that is climbed on the steering in the vehicle.
