The working principle of the automotive fuel injector is to atomize the fuel and inject it into the engine cylinder through electromagnetic control, as follows:
Electromagnetic control: When the engine control unit (ECU) sends a control signal, the coil inside the fuel injector generates a magnetic field, lifts the needle valve, and allows the fuel to be ejected through the nozzle. When the ECU stops power supply, the magnetic field disappears, and the needle valve closes under the action of the return spring, and the fuel injection stops.
Fuel injection: The fuel injector atomizes the fuel through high pressure and injects it into the engine cylinder. According to different injection methods, it can be divided into single-point electronic fuel injection and multi-point electronic fuel injection. Single-point electronic fuel injection installs the injector at the carburetor position, while multi-point electronic fuel injection installs the injector on the intake manifold of each cylinder.
When using the fuel injector, to ensure its normal operation and extend its service life, the following points need to be noted:
Regular cleaning: To avoid the clogging of the fuel injector affecting the vehicle performance, it is recommended to have it cleaned at a professional repair shop regularly. However, be careful that the cleaning frequency should not be too high, and the correct cleaning method should be adopted to extend the service life of the fuel injector.
Avoid long-term idling: Long-term idling is prone to causing carbon deposits and blockages in the fuel injector. To maintain the good working condition of the fuel injector, it is recommended to run at high speed regularly to reduce the formation of carbon deposits.
Timely inspection and replacement: When the vehicle has abnormal phenomena such as increased fuel consumption, excessive emissions, difficult starting, and unstable idling, it may be related to the failure of the fuel injector. At this time, it should be inspected in time, and if it is damaged, it should be replaced immediately.
