Automobile oil circuit cleaning notice two or three things

There are several types of automobile oil circuits

What we usually call the automobile oil road usually includes two kinds: oil road and gasoline road.

The oil path refers to the way the oil runs through the oil pump inside the engine. The gasoline road is also called the fuel system, which refers to the pipeline between the car fuel from the tank to the engine combustion chamber.

The oil circuit mentioned in this article refers to the latter, that is, the fuel system of the car. It includes: fuel filter, gasoline pump, fuel pressure regulating valve, gasoline pipeline, carbon tank, fuel nozzle.

The role of oil circuit in engine operation:

For the complete working principle of the various components of this entire oil circuit, most of the owners are not professional and technical personnel, do not have to study very thoroughly, just understand the basic working principle. The general working principle is also very simple, including the following steps:

1. The oil pump pumps the oil in the tank into the pipeline to maintain a pressure of about 2.5 kg.

2. The fuel filter is in the middle of the oil pump and the fuel pressure regulator, and plays a filtering function to filter out harmful particles and moisture in the fuel.

3. The fuel pressure regulator controls the pressure in the oil circuit, and then the fuel is injected into a mist through the fuel injection nozzle, and the air is mixed into the cylinder (some engines also use direct injection in the cylinder).

Car cleaning equipment - Oil circuit reasons:

After the fuel system has worked for a period of time, the carbon deposits and colloids formed by combustion will adhere to the fuel nozzle, making the fuel nozzle stick or even block.

The impurities and dust in the air and gasoline will also cause the oil circuit to be blocked or blocked, and eventually form carbon deposits and deposits on the fuel injection nozzle (the valve, combustion chamber, and intake pipe will also form carbon deposits, but this article only refers to the carbon deposits on the fuel injection nozzle).

General method of cleaning oil circuit

1. Add fuel cleaner directly to the fuel tank, which is the easiest way, but the general product effect is not lasting, and the cleaning effect is not complete. Suitable for vehicles with short mileage (in-cylinder direct injection motor cleaning). Direct injection into cylinder

2. Use non-dismantling and washing machine for cleaning (most repair factories use the "bottle" method, which is also a form of non-dismantling and washing machine). This method is through a special no-disassembly cleaning machine, the engine inlet oil pipe and return oil pipe are connected with the inlet oil pipe and return oil pipe of the no-disassembly cleaning machine, and the special interface is connected to the inlet oil pipe and return oil pipe to form a loop. However, the cleaning of the oil circuit alone, the effect is obvious, is a good way to clean the oil circuit.

3. Directly remove the entire oil circuit and thoroughly clean it.

This method is suitable for vehicles with more than 100,000 kilometers and very serious oil road congestion. It goes without saying that the effect must be good, but the time spent is also the longest, and the technical requirements for maintenance personnel are also high standards. And if you usually pay more attention to the care of the car, it is generally not necessary to use this method. So this is a last resort.

Frequency of cleaning oil circuit

Cleaning the oil circuit is an essential maintenance project, but it is not necessary to do every maintenance. Take washing your hair for example, washing your hair once a day is clean, washing your hair once a week is disgusting, but washing your hair every hour is unnecessary, not only unnecessary, but also harmful to your hair.

The cleaning of the oil circuit is the same, some feel that the cleaning of the oil circuit is useless, never clean the oil circuit, there will be possible failures. There are also some owners like online reports, listening to some profit-making black heart repair shops, cleaning too often.

It seems to be "love clean", in fact, it is completely unnecessary, not only unnecessary, because the cleaning agent contains a large number of chemical components, overfrequency cleaning will also cause great damage to the three-way catalytic converter, causing unnecessary damage to the vehicle. The normal cleaning frequency should be 30,000-40,000 km/time, and increase or decrease according to the road conditions and vehicle conditions of their own driving, for example: urban road congestion will accelerate oil road congestion.
