Transformer Transformer is a electrical machine and it transfer electric power from one circuit to another without change in frequency.It has no moving part in it. It has a very high efficiency .The efficiency above 10%. In the transformer basically work on the mutual induction between the two circuit linked by a common magnetic field. It consists two winding one is primary winding and other is secondary winding.In the primary winding electrical energy is feed from the AC.and in the secondary winding energy is receive. Both winding are physically isolated but coupled magnetically. Classification of transformation 1.On the basis of phase (a).single phase transformer (b).three phase transformer 2.On the basis of construction (a).shell type transformer (b).core type transformer 3.On tha basis of power rating (a). Distribution transformer (b). power transformer 4.on the basis of working (a).step up transformer (b).step down transformer Principle- Transformer works o...

Engine Control Unit(ECU) It is the brain of engine that control all the functioning of the engine.lt serve several function which include regulating and maintaining the amount of fuel and air in the fuel injection part and help in increasing Horsepower of the engine. Working of ECU Engine control unit is the integral of Electronic fuel injection.Electronic fuel injection can be divided into subsystem namely Air Induction system,fuel delivery system and the electronic control systems and from here the function of the ECU. The electronic control system of an EFI is where you will find the ECU. Aside from the ECU, this is also where you will find various sensors, fuel injector assemblies and any related fuel injection wiring. Functions of fuel injection ECU system A fuel injection ECU system has several functions. Probably one of the most important function of the ECU is it controls the fuel mixture used by the engine. The Engine Control Unit or ECU determines the amount...
