How to remove the fuel injector?

Remove the engine hood, remove the intake pipe, unplug the power plugs of the four injectors, and the throttle and idle motor. There are two screws on the bracket of the fuel injector assembly. Unscrew the left and right screws of the fuel injector assembly, and remove the assembly to take out the fuel injector. The following is an introduction about the choke: 1. Brief introduction of fuel nozzle: Now the fuel nozzle used in automobile is actually a simple solenoid valve. When the electromagnetic coil is energized, the needle valve is sucked up to open the nozzle hole, 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. 2. The main reason for the nozzle sticking is that the diesel oil is unclean, and there are impurities in the high-pressure oil pipe, which makes the needle valve couple not closed tightly, and the high-pressure gas in the combustion chamber flows backwards and burns the needle valve couple.
