How much does it cost to clean the fuel nozzle?

Clean the injector 200 ~ 300 yuan once.

At present, the fuel injector for automobile is actually a simple solenoid valve. When the electromagnetic coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is ejected at high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, forming mist, which is beneficial to full combustion.

definition

The injector itself is a normally closed valve (normally closed valve means that the valve is always closed when there is no control signal input, and normally open valve means that the valve is always open when there is no control signal input), and a valve needle moves up and down to control the opening and closing of the valve.

When the ECU sends the fuel injection instruction, its voltage signal will make the current flow through the coil in the fuel injector, generate a magnetic field to attract the valve needle and open the valve, so that the fuel can be ejected from the fuel injection hole.
