There are some reasons for fuel injector failure:
1.Pollution and restrictions
All the fuel burned by the engine eventually passes through the injectors. As a result, the injectors are susceptible to contamination and carbon deposits, ultimately restricting the flow of fuel. There are many factors that contribute to this, including fuel quality, driving conditions and injector design.
2.Electrical failure
The injector consists of a coil wound on a spool. When an electric current passes through the coil, it creates a magnetic field that causes the pivot to move away from its base, allowing fuel to be injected. When the current is cut off, the magnetic field disappears and the spring pushes the pivot against its base, cutting off the flow of fuel.
3.Engine blowby
Blowby is fuel and oil residue blown through the piston into the crankshaft during compression. Your car's PVC system should be able to keep the blow-by air out, but if the air filter isn't catching the blow-by air, or the PCV system isn't working properly, this sludge can end up clogging your fuel injectors.
4.Poor injector atomization
When the injection pressure is too low, the nozzle is worn and carbon deposited, the spring end face is worn or the elasticity is reduced, which will cause the injector to open too early and close too late, resulting in poor atomization.
5.Needle valve stuck
The engine power drops, vibrates, and even fails to start in severe cases.
6.Oil dripping from the injector
When the injector is working, the sealing cone of the needle valve body will be frequently and strongly impacted by the needle valve, and high-pressure fuel will be continuously sprayed out from there, causing the cone to gradually wear or have spots, causing the injector to drip oil.
How to reduce problems?
1.Regular inspection and cleaning
Check them regularly to prevent sediment buildup.
2.Use of fuel additives
Another good way to keep your injectors healthy is to regularly add injector cleaner. You just add it to your tank.
3.Regular engine maintenance
Regular oil and filter changes go a long way in keeping your engine healthy. If the engine is not running efficiently, it will put extra pressure on the injectors. It is also important to replace the fuel filter regularly to ensure proper fuel flow.
4.Good driving habits
Driving the vehicle hard and making short starts and stops will increase the wear on the injectors. Allowing the engine to cool down before shutting it off will extend the life of the injectors. Therefore, a well-maintained fuel injection system will keep your vehicle running for many years.
What should I do if the fuel injector fails?
When problems occur, it may be due to a lack of regular cleaning of the fuel injectors. To prevent any form of clogging, it can be cleaned at 30, 000 miles. If the O-ring leaks, replace the O-ring promptly. In addition, the injector may be damaged, so it needs to be replaced with a new injector according to the specific vehicle type.
