The injectors in the car are responsible for fuel injection. If this procedure occurs with deviations from the norm, then this leads to a violation of the dynamic characteristics of the vehicle, an increase in fuel consumption and can cause engine instability. A similar situation is associated with the appearance of extraneous noises under the hood and the presence of black exhaust gases. The car begins to start with certain difficulties, and leaks appear on the surface of the engine.
If these signs are present, you should immediately contact a car service. Further operation of the vehicle may lead to failure of the entire power plant. It is recommended to repair the injectors in a car service, because this procedure must be carried out in a clean room and according to a certain technology. High-quality repair work is possible with experienced and qualified specialists and the necessary equipment. All this is available at the car service.
The injectors are repaired when removed. Before dismantling, you will need to clean the engine with compressed air. If you do not do this, then during the process of removing the injectors, debris will get inside the engine, which will lead to its breakdown.
You need to unscrew these elements of the power plant with an open-end wrench. Using any other tools will damage its edges. This procedure is carried out carefully, because there is a risk of damaging the seat. The master will apply Litol to the thread, which will protect it from getting pieces of sealant.
After removing the injector, the master, using a maximeter, determines the pressure under which the fuel is injected. Then, he checks the operation of the sprayer, injecting onto a clean sheet of paper. When the injection system is functioning normally, all traces should be at an equal distance from the center and have the same configuration.
Having made sure that the injector is faulty, the auto mechanic disassembles it into its components. He washes all its parts in kerosene and then blows them with compressed air. A visual inspection by a specialist is enough to determine the worn out elements of the injector, which are subject to replacement. A large amount of accumulated dirt can also be the reason for its poor operation. In this case, the repair will be limited to cleaning and flushing the injection system.
After the repair is complete, the injector is assembled, and the threads are treated with grease – copper or graphite. Screwing in begins by hand. People resort to using tools when their hands are no longer strong enough.
