Airless(or) Solid injection system

In this niethod, the fuel is supplied at high pressure to the combustion chamber in
atdmised state.t This method requires a pump to deliver the fuel at high pressure (150 bar to 300 bar) to the fuel injector.
So, the main components of this system are fuel pump and fuel injector. The fuel pump is operated by a cam which 18 mounted by a cam shah. The power required to operate the cam is taken from the engine crank shaft.This system is further classified according to the location of basic components (fuel pump and fuel injector) and the method used to meter the fuel as

common rail system
Individual pump and nozzle system
Distributor system

Flux-cored arc welding

Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply. An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the atmosphere, producing both gaseous protection and liquid slag protecting the weld. The process is widely used in construction because of its high welding speed and it portability.

Injection Molding

Injection Molding Injection machine The injection machine is a machine that melt plasticize the molding material inside the heating cylinder and inject this into the mold tool to create the molded product by solidifying inside it. The injection machine is constructed of a mold clamping device that opens and closes the mold tool, and device that plasticize and inject the molding material. There are several types in the injection machine, and the difference is made by how these two devices are arranged.

working of breaking system in automobiles

Definition of automobile brake system Actually, vehicle can be regard as energy conversion device, which transfers the momentum into heat, in other words, which transfers the kinetic energy into thermal energy. The brakes are used to reduce the speed of the vehicle, and the speed of conversion determines the rate of the vehicle slows down.
