Auto Parts Diesel engine fuel injector nozzle 093400-7680 for Auto Fuel Common Rail Nozzle injector parts

A single nozzle can be cleaned using special chemicals.  For example, the same additives that are added to the fuel to clean the system or the so-called “Carburetor Cleaner”.  In this case, you need to act according to the following algorithm:

prepare in advance “Carburetor Cleaner” (or its equivalent in the form of a spray can), a contact button without fixing the closed position, a syringe with a volume of 5 ml or more, a tube for extending the neck of the syringe with a seal, an empty container, preferably a large volume (5-10 liters ), charger from a mobile phone with a cut plug, contact wires with terminals;

then you need to insert the test nozzle into the back of the syringe (as tightly as possible, with or without an elastic band);

after that, connect the terminals through the button to the charger and plug it into the outlet;

insert the tube into the sprayer of the cleaning agent, and deploy the back of the nozzle into the prepared empty container;

after that, press the sprayer so that a certain amount also gets into the nozzle;

press the contact button to activate the nozzle.

If the nozzle is in good order, detergent should come out under pressure from its reverse side.  The purge procedure must be repeated several times to achieve the desired degree of purity.

If your car is equipped with low-resistance injectors, then you need to press the injector open button for a fraction of a second. If you have high-resistance nozzles, then you can hold the button for 2-3 seconds.
