How to Clean Fuel Injection Nozzle of Data Center Generator Set

Dec. 14, 2021

In order to reduce the fuel injection nozzle failure of data center generator set and make the fuel injection nozzle function normally, users need to maintain the fuel injection nozzle of the unit. If the fuel injection nozzle is not cleaned for a long time, it will produce oil dirt. If these oil dirt block the fuel injection nozzle, it will lead to poor fuel injection. Therefore, the fuel injection nozzle of the unit should be cleaned. What are the requirements for the cleaning frequency of the fuel injection nozzle of diesel generator?


The fuel injection nozzle of data center generator set is an important component to realize fuel injection in the fuel supply system. Its function is to atomize the fuel into fine oil droplets according to the characteristics of diesel engine mixture and inject them into specific parts of the combustion chamber. The fuel injector should meet the requirements of different types of combustor for spray characteristics.

How to Clean Fuel Injection Nozzle of Data Center Generator Set

Some people think that the fuel injection nozzle should be cleaned frequently. But this is also one-sided. The fuel injection nozzle should be cleaned scientifically, otherwise it will be useless. In fact, there are not many parts that need to be cleaned. Why?


First, the fuel is filtered by the dense screen of the fuel pump and then filtered by the fuel filter. The size of impurity particles of diesel oil flowing through the fuel injection nozzle is not an order of magnitude compared with the clearance of the fuel injection nozzle.


Second, the glue contained in the fuel oil is ejected at high speed when passing through the gap, which is difficult to survive. The so-called drop of water wears through the stone. Moreover, the needle valve and contact surface are knocked many times a day.


Third, most of them adopt out of cylinder injection mode, and the temperature here is not high, which is several times better than the working environment of spark plug.


The position that is really easy to affect atomization should be the outer surface of the fuel injection port of the fuel injection nozzle. The so-called cleaning agents are things such as benzene or benzene aromatic hydrocarbons. When they are added to the engine for combustion, they can dissolve part of the carbon deposit. The cheap cleaning agent is carburetor cleaning agent, which can also be added for combustion.


Some friends always feel good when they see the black water flowing out from the back of the exhaust pipe when cleaning the carbon deposit. In fact, 90% of the black water is not the carbon deposit inside the generator. Moreover, after washing and drying, burning fuel oil still continues to produce carbon deposition until it is in equilibrium, which is of little significance. So don't wash it unless you have to.


The cleaning frequency of fuel injection nozzle of data center generator set is determined by the requirements. Of course, the specific methods and methods should be appropriate to the specific situation. I hope the above introduction of Dingbo power can bring reference to users.
