A fuel injector is an electro-controlled valve that uses to spray out the fuel. In the petrol fuel injection system, the injector acts as a door to spray fuel from fuel lines into the intake manifold. The injector function is not only a sprayer, but the injector also atomizes the fuel in the intake manifold. When fuel is in atomization form ...

A blocked or clogged fuel injector may be fixed by adding a fuel injector cleaner to the fuel tank the next time you fill the tank at the pump. If that clears the contamination, you can then add cleaner frequently to reduce the chance of the injectors becoming clogged or blocked open in the future.
dimensions are referred to for designing the nozzle. The fuel injection nozzle comes under the function of the high pressure of the fuel even as the fuel injector is injecting, even as the pressure of the fuel within the fuel injection may be very low when the injection is give up. The liquid load the fuel injection receives is trade.

The first reason to replace a fuel injector is for an external leak. Although uncommon, any raw fuel that leaks from a fuel injector is a fire hazard, and that injector should be immediately replaced. If a fuel injector becomes clogged from debris in the fuel or carbon deposits on the nozzle can't be cleaned, changing it is necessary.
