Types of patterns used in Casting Process Types of patterns: The following factors affect the choice of a pattern. (i)  Number of Castings to be produced. (ii)  Size and complexity of the shape and size of casting (iii)  Type of molding and castings method to be used. (iv)  Machining operation (v)  Characteristics of castings Different types of patterns: The common types of patterns are: 1)  Single piece pattern 2)  Split piece pattern 3)  Loose piece pattern 4)  Gated pattern 5)  Match pattern 6)  Sweep pattern 7)  Cope and drag pattern 8)  Skeleton pattern 9)  Shell pattern 10)  Follow board pattern Figure 1:  Single piece, Split, Match-plate, Cope and Drag Pattern Single piece pattern: This is the simplest type of pattern, exactly like the desired casting. For making a mould, the pattern is accommodated either in cope or drag. Used for producing a few large castings, for example, stuffing box of steam engine. Split pattern: These patterns are split along the part

When you turn the key off the car will deny the engine intake is it will stop fuel supply. In modern cars with electronic fuel injectors, the engine control unit stops  operation of the electronic fuel injector Where as in bike when you turn off the key it will break the power supply to the spark plugs. Then engine stops....herrrrr.

So, it's very important to know how to read and create drawings. In this course you'll start by creating 2D drawings in AutoCAD, and then move to parametric 3D modeling in Autodesk Inventor. You'll also learn how to collaborate with a global design team using Autodesk 360 cloud technology. Like drawing, collaboration is an important skillset to develop for your professional career in engineering. When you're ready, let's get started with the course.

Jet engines :- Jet engines are  internal combustion engines  discharging hot exhaust gases at high velocity that generate thrust. Unlike the internal combustion engines in automobiles & trucks which convert the up & down movement of the piston to rotary movement of crankshaft, jet engines simply produces power by sucking air at the front side & discharging it at the back side. Types of jet engines/gas turbines :- Turbojet engines  :-   Animation of working of a jet engine. Also you could see that air is flowing faster while leaving the nozzle than while entering. These were the first jet engines. The fans in the front does the work of compressor. The compressed air is then forced into the combustion chamber. As the air is already at high pressure and high temperature, fuel is injected into it. Combustion takes place into the chamber & high amount of exhaust gases are produced. These hot expanding gases are then made to flow through turbine which causes the

What is Engine? What are Main Types of Engine? Today we will discuss about engine and types of engine used in automobile. Any device which can convert heat energy of fuel into mechanical energy is known as engine or heat engine. Engine is widely used in automobile industries or we can say that engine is the heart of an automobile. Basically engine may be classified into two types. Types of Engine: 1. External combustion (E.C.) Engine It is an engine in which combustion of fuel take place outside of the engine. In this type of engine heat, which is generated by burning of fuel is use to convert the water or other low boiling temperature fluid into steam. This high pressure steam used to rotate a turbine. In this engine we can use all solid, liquid and gases fuel. These engines are generally used in driving locomotive, ships, generation of electric power etc. Advantages of E.C. engine- In these engines starting torque is generally high. Because of exter
