There are two or three things you need to know about car oil cleaning

What we usually refer to as automobile oil roads usually include two types: motor oil road and gasoline road. The oil circuit refers to the path inside the engine through which the oil runs through the oil pump. Gasoline is also called fuel system, which refers to the pipeline between car fuel and the combustion chamber of the engine.

 

The oil circuit in this article refers to the latter, which is the fuel system of the car. It includes: fuel filter, gasoline pump, fuel pressure regulating valve, gasoline pipeline, carbon canister, and fuel injector.


 

The main role of automobile oil cleaning is:

Prevent the fuel supply system from being blocked to ensure normal driving, remove carbon deposits in the oil circuit, improve the nozzle’s rubber quality, improve the atomization of the nozzle, promote full combustion, reduce knocking, knock on the cylinder, increase power, reduce fuel consumption, and protect the engine , Restore the vehicle’s startability, power and economy.


Reasons for cleaning the oil circuit:

After the fuel system has been working for a period of time, the carbon deposits and colloids formed by combustion will adhere to the fuel injection nozzles, causing the fuel injection nozzles to stick or even block. The impurities and dust in the air and gasoline will also cause the oil path to be blocked or blocked, and eventually form carbon deposits and deposits on the fuel injection nozzle. If the oil circuit is not cleaned for a long time, carbon deposits and deposits will block the needle valve and valve hole of the injector, affecting the performance of the precision components of the injection system, resulting in poor injection, poor atomization, and even non-injection. As a result, the car’s idling speed is unstable, fuel consumption rises, acceleration is weak, and starting is difficult.

If the oil circuit is not cleaned for a long time, carbon deposits and deposits will block the needle valve and valve hole of the injector, affecting the performance of the precision components of the injection system, resulting in poor injection, poor atomization, and even non-injection. As a result, the car’s idling speed is unstable, fuel consumption rises, acceleration is weak, and starting is difficult.

 

  • General cleaning method:
  1. Add fuel cleaner directly to the fuel tank. This is the easiest method, but the effect is not lasting and the cleaning effect is not thorough. Suitable for vehicles with short mileage.
  2. Use “Bang Hang” method for cleaning.

 

The “hanging bottle” method can simultaneously clean the carbon deposits and deposits of the oil circuit and the valve, which is also the method generally recommended by car repair shops.

  1. Use a disassembly-free washing machine for cleaning.

This method uses a special no-disassembly washing and cleaning machine to connect the engine’s oil inlet and return pipes with the no-clean cleaning machine’s oil inlet and return pipes, and uses a special interface to connect the oil inlet and return pipes to form a circuit. It is convenient and quick to operate, but it is generally not recommended because it only cleans the fuel injection nozzles and does not clean the carbon deposits on the valves. However, on the cleaning of the oil circuit, the effect is obvious, it is a good way to clean the oil circuit.

  1. Remove the entire oil path directly for thorough cleaning.

This method is suitable for vehicles with more than 100,000 kilometers and very severe oil jams. Needless to say, the effect is definitely the best, but it also takes the longest time and has the highest technical requirements for maintenance personnel. And if you usually pay more attention to car care, this method is generally not necessary. So this method is also a last resort.

 

  • Frequency of cleaning the oil circuit:

Cleaning the oil circuit is an essential maintenance item, but it is not necessary to do every maintenance. For example, washing your hair once a day is clean, and washing your hair once a week is disgusting, but washing your hair once an hour is not necessary. It is not only unnecessary, it also causes hair damage.

The cleaning of the oil road is the same. Some car owners carelessly think that cleaning the oil road is useless. Never cleaning the oil road will cause the above mentioned consequences for a long time. There are also car owners like the ones mentioned at the beginning of this article. They heard that some black-hearted repair shops that only paid for profits had been cleaned frequently. It seems to be “love clean”. In fact, it is completely unnecessary, not only unnecessary. Due to the large amount of chemical components in the cleaning agent, over-frequency cleaning will cause great damage to the three-way catalyst and unnecessary damage to the vehicle.

The normal cleaning frequency should be 30,000 km / time, and it should be appropriately increased or decreased according to the driving conditions of the vehicle and the vehicle conditions. For example, the congestion of urban road conditions will accelerate the oil road jam.

  • How to maintain automobile oil road?

“Three-point repair, seven-point maintenance” If you want to extend the cycle of cleaning the oil circuit and protect the oil circuit of your car, daily maintenance is also essential. Summarized into the following points:

  1. Refueling should go to a regular gas station and fill with high-quality fuel.
  2. You can choose to add some fuel enhancement treatment agent to the fuel tank after a certain period of time.
  3. During maintenance, we must pay attention to the inspection and replacement of the fuel filter to enhance the filtering effect of the fuel.

 

to sum up:

As the saying goes, “three points of cultivation, seven points of maintenance.” If you want to extend the cycle of cleaning the oil circuit and protect the oil circuit of your car, daily maintenance is also essential. Summarized into the following points: 1. Refueling should go to a regular gas station and add high-quality fuel. 2. You can choose to add some fuel cleaner to the fuel tank after a certain period of time, but it should not be too frequent. 3. During maintenance, we must pay attention to the inspection and replacement of the fuel filter to enhance the filtering effect of the fuel.
