Baotou beiben Heavy Truck Parts Injector copper sleeve is damaged, some electronic controlled high pressure common rail engine common fault, the fault are really annoying, once the fuel injector copper sleeve is damaged, the antifreeze will with diesel oil return pipeline into the tank, causing mixed antifreeze and diesel, if it meets the oil-water separator suck. Then the damage of high pressure oil pump injector, so how can we point the day and await for it, to prevent the failure?
Why old bad coolant is the key
This is a problem in many a commonplace talk of an old scholar, a card, especially a card in the south, because no antifreeze, antifreeze in the absence of later, often use tap water instead of. This does not seem to be a problem in the short term, but a long time will cause the damage to the fuel injector copper sleeve and sealing ring.
Some card friends said that I have been using the antifreeze ah, but my copper sleeve is still bad, and this is why? This situation in general, is in the replacement of antifreeze, when to buy a fake, fake antifreeze and water, also on the copper sleeve and sealing ring corrosion, over time will produce the above fault.
Cooling liquid without reason to reduce the timely check out
When we found that the cooling liquid in the absence of no reason, and can not find running outside the case of leakage, it should be checked in a timely manner. To determine whether the Baotou beiben Heavy Truck Parts Injector copper sleeve damage is very simple, first look at the oil tank will become turbid, if the tank is not clear, can see the water filter, which can visually see if you find any antifreeze, antifreeze, so can be found, is your fuel for copper sleeve damage.
In general, Baotou beiben Heavy Truck Parts Injector copper sleeve is the need to replace the cylinder head down, but the master in the private sector, many specialized electronic controlled diesel engine master, homemade tools can not lift the cylinder head can be replaced. Although there is a simple way, or need to pay attention to prevention, after all, is also a need for a lot of money to repair, bad fuel injector and then damaged, it is more expensive.
