Injector FAQ
FAQ: Common Rail Fuel Injector Frequently Asked Questions. Pin stuck?
ERIKC Answer:The moisture or acid in diesel oil will cause the needle valve to rust and get stuck. After the conical surface of the needle valve is damaged, the combustible gas in the cylinder will invade into the mating surface to form carbon deposits, which will cause the needle valve to seize the fuel injector. Loss of fuel injection causes the cylinder to stop working.
Remedy: Remove the injector, remove the nozzle assembly, use the tool to pull out the needle valve. If it is not easy to pull out, you can first put the fuel injector into the diesel heating about 20 minutes and then take it. Take a copper pad on the tail of the needle valve, and pull the pliers to grip the tail while rotating. Remove it, place it in the cleaning solution, clean it, and reload it. If it is dirt intrusion, it will be flexible after cleaning. If it is due to the flexible geometry of the coupling, it is necessary to add a small amount of grinding paste, gently polish it, and polish it.
FAQ: Common Rail Fuel Injector FAQ. Injector Poor Atomization?
ERIKC Answer:When the injection pressure is too low, the nozzle hole wears carbon, the spring face wears or the elastic force drops. This will cause the injector to open in advance, delay closing, and cause poor atomization of the fuel injection. The power of the diesel engine was reduced, the exhaust gas was black smoke, and the machine operation sound was not normal. In addition, because the diesel droplets with too large particle size do not fully burn, they flow down the cylinder wall into the oil pan, which increases the oil level of the oil, lowers the viscosity, deteriorates the lubrication, and may cause an accident of burning the cylinder. At this point, the injector should be disassembled, cleaned, overhauled, and recommissioned.
