What are the injectors for Citroen C3 used for?

The role of an injector on Citroen C3

The engine of your Citroen C3 is fitted with cylinders, usually there are at least four, but depending on the power of your engine there may be more. These are the cylinders that will operate the engine, however for this they must be supplied with an air-fuel mixture. The latter will be compressed and heated and this will produce the combustion which will give energy to the engine.

Thus the supply circuit works in this way, the booster pump will send fuel from the tank, which will then be sanitized thanks to the fuel filter to reach the injection system.
As regards the injection system, it consists of an injection pump. The latter will distribute the fuel under pressure and at precise doses inside the common rail. This will feed each injector of your Citroen C3. Then the injector will vaporize the fuel in the combustion chamber at a well defined time.

So in summary : the role of the injection system of your Citroen C3 is to give sufficient dose gasoline under pressure inside the combustion chamber contained in each cylinder of the motor.

The type of injection on Citroen C3

Be aware that there are a number of injection methods. Non-recent versions often have a mechanical injection . But being very fuel consuming, it was replaced by a electric injection . The latter works with the help of the ECU which will measure according to certain parameters the sufficient quantity of gasoline in order to reduce consumption.
Then the injection can be direct or indirect . You should know that at present the most common is direct injection. In fact, this will allow the fuel under pressure to be inserted directly inside the combustion chamber. Unlike the indirect which will insert the fuel inside the intake manifold for gasoline or inside the pre-combustion chamber for diesel.

this being indirect injection will consume more gasoline but it will provide better combustion, therefore less emission of fine particles . And conversely direct injection will consume less but will be more polluting .
