That which injects is called the injector . These devices are used for fluid injection: that is, to introduce a liquid somewhere.
Among the words that can function as synonyms for injector we find syringe, syringe, valve or irrigator, for example.
Internal combustion engines have injectors that are responsible for providing the necessary amount of fuel for their operation. The injectors therefore supply fuel to the combustion chamber, trying to distribute it homogeneously.
The injection pump is responsible for propelling the fuel. This pump generates the pressure necessary to activate the operation of the injectors, which spray the fuel into the combustion chamber. The injectors can be electronic or mechanical depending on the type of engine.
In addition to those exposed, there are other types of injectors in car engines. We are referring to the following:
-Direct injection, which is the system that allows fuel to be injected directly into the combustion chamber.
-The indirect injection ones, which are the ones that are located in the so-called intake manifold.
Injection systems in car engines are considered to be very beneficial since they achieve more efficient fuel consumption, achieve greater and better engine performance, considerably reduce the heating of the aforementioned engine, and contribute to pollution. less and, in addition, they considerably improve the starting of the car.
In the same way, we cannot ignore that there are more types of injection systems. Among those are these:
-Single-point injection, which uses a single injector.
-Multipoint injection, which is identified by having the same number of cylinders as injectors.
-Intermittent injection, which is defined as being a fully electronic system where the injectors work intermittently. It is further divided into sequential injection, semi-sequential injection and simultaneous injection.
-Continuous injection, which, as its name indicates, is carried out without interruptions of any kind, even when the engine is idling.
Problems with vehicle injectors are common. In fact, current cars usually have sensors that detect when a failure occurs in the system and mark the problem on the dashboard through a light on. One of the most common failures is that an injector becomes clogged due to the accumulation of dirt.
Dirty injectors can cause a car to consume excess fuel, cause the engine to shake when running or have little power , or cause the car to jerk when starting. In any case, it will be necessary to clean these elements or, if they are damaged, to replace them.
Beyond their use in engines, early injectors were often used in steam boilers . These injectors used the steam generated by the boiler, which came out of the nozzle at high speed and mixed with the water, producing condensation. As a result of the process, a jet of water emerged with the kinetic energy necessary to enter the boiler.
