The internal combustion engine works on the sequence of separate process intake, compression, combustion, expansion and exhaust. It does not operate on thermodynamic cyclic because it involves an open system. The working fluid (fuel and air mixture) enters into the system in intake stroke and leaves it in exhaust stroke. The working fluid does not …
Today we will discuss about main parameters used to test a engine performance. Engine testing is very important part of engine design. The engine performance indicates by the term efficiency. For the testing basis, five major efficiencies are used which we have discussed in the last post. If you have not read the last article first …
The engine performance is indicated by the term efficiency. Today we will discuss about diesel engine efficiency and petrol engine efficiency. In auto industries, five engine efficiencies are used to check an engine performance. These efficiencies are Indicated thermal efficiency, Brake thermal efficiency, Mechanical efficiency, Volumetric efficiency and Relative efficiency. These all are that parameters which …
Today we will discuss about welding and types of welding. Welding is a process of joining similar and dissimilar metals or other material by application of heat with or without application of pressure and addition of filler material. It is used as permanent fasteners. Welding is essential process of every manufacturing industries. In fact, the …
Today we will discuss about belt drive and its types. We all know that belt drives are used to transmit power form one shaft to another, which have not common axis. In the fact belt drive is used to transmit power. One alternate of belt drive is gear drive but gear drive is not economical …
Today we will discuss screw thread terminology and types of threads which are used in industries. The treads are used on a cylindrical shaped surface and used as the fasteners. Threaded fasteners are commonly used in all industries and are very popular. A threaded joint is much stronger and removable than the unthreaded joints like …
We all know about air conditioning system. The automotive air conditioning system is also works on the reverse Brayton or Rankine cycle. As like all air conditioning system the aim of automotive air conditioning is to control the temperature and humidity of the atmospheric air and circulate the same in the automobile. The automotive air conditioning system …

Today we will discuss how many types of belts used to power transmission. In my last post we have discussed types of gears which are used to transfer power form one shaft to another. Belts are also done same. It is used to transmit power form one shaft to another by means of pulleys which …
Today we will discuss about what is gear and its types like Spur gear, helical gear, worm gear, rack and pinion etc. It is observe that gears are used almost in all mechanical devices to obtain different torque and speed ratio. It is a positive power transmission device and basic component of all mechanical devices. There are various types …
Today we will discuss about continuous variable transmission. We also discuss about advantages and disadvantages of CVT transmission. Till now we know that we use gear box to change the torque according to the driving requirement. For this we have four to five gear ratio which we shift and change the gear. But CVT is an …
