DeutschCommon reasons for the damage of the copper bushing of the fuel injector, how to judge whether the fuel injector is damaged, and how should we disassemble the copper bushing of the fuel injector once it is damaged?
● Common causes of damage to the copper sleeve of the injector
(1) In fact, this is already a commonplace question. Many people, especially those in the south, do not need antifreeze and often use tap water instead after the antifreeze is missing. It seems that there is no problem in the short term, but after a long time, it will cause damage to the copper sleeve and sealing ring of the injector.
(2) Some people use antifreeze, but the copper sleeve is still broken. Why is this? In this case, generally speaking, when the antifreeze is replaced, fake antifreeze is bought. Like water, the fake antifreeze will also corrode the copper sleeve and sealing ring, and the above faults will also occur over time.
● How to judge whether the copper sleeve of the fuel injector is damaged
When we find that the coolant is lacking for no reason, and there is no leaking or leaking outside, we should check it in time. It is very simple to judge whether the copper sleeve of the fuel injector is damaged. First, check whether the oil in the fuel tank becomes cloudy. If there is antifreeze, it can be basically determined that the copper sleeve of your fuel injector is damaged.
Generally speaking, the copper sleeve of the fuel injector needs to be replaced by lifting the cylinder head down, but the experts are among the people, and many experts who specialize in electronically controlled diesel engines have self-made tools, which can be replaced without lifting the cylinder head.
