Will it damage the fuel injector when cleaning the hanging bottle

Doing it the right way won't damage the injector.

It can be removed from the car for cleaning by removing the fuel rails, removing the injectors, and using carburetor cleaning agent (10 yuan a barrel). Auto parts stores are sold) clean the inlet and outlet carbon deposits of the injector, and then add 12V voltage to the injector, connect the thin tube of the carburetor cleaning agent at the inlet of the injector, too thin can be wrapped with black tape and thickened, one person holds it with both hands to ensure that the carburetor cleaning agent and the injector inlet do not leak oil, and the other person jogs the 12V power supply to make the cleaning agent sprayed out intermittently, until the oil mist sprayed by the injector is fine, and one can be completed evenly.

Others and so on. Pay attention to the rubber sealing ring of the injector, which can not be aged or defected. The oil mist from the unwashed injector looks like rain, and the oil mist from the washed injector looks like a mist.

After installing the injector, observe whether the upper and lower sealing rings of the injector leak oil, and there can be no gasoline leakage. Otherwise, change the seal.

Basketball. Based on what you say, the first thing to tell you is that the injector will never be damaged when cleaning the carbon deposit. It may be that the injector or intake and exhaust valve is not closed tightly because the injector or impurities are stuck on the injector or intake and exhaust valves during cleaning. So there is a jitter phenomenon.

It is recommended that you also check the spark plug for fault.

It is convenient and fast to hang the bottle, and the commonly used method now has the effect of cleaning not being thoroughly dismantled.

Summary. Hello friends. The hanging bottle method of automobile fuel injector cannot be cleaned.

Cleaning with hanging bottles is the previous method, and the hanging bottle method has been phased out because the operation process is too cumbersome and cannot completely clean up the precipitated carbon deposits. Nowadays, the cleaning machine is mostly used instead of the gasoline pump to pump the cleaning agent for cleaning, that is, the cleaning agent is poured into the cleaning machine, the cleaning machine is connected to the oil pipeline of the engine, the gasoline pump is disconnected, the engine is started, and the idle speed is more than 15 minutes until the cleaning agent is used up.

What is the effect of the car hanging bottle.

Hello friends. The hanging bottle method of automobile fuel injector cannot be cleaned. Cleaning with hanging bottles is the previous method, and the hanging bottle method has been phased out because the operation process is too cumbersome and can not completely clean up the precipitated carbon deposits.

Nowadays, the cleaning machine is mostly used instead of the gasoline pump to pump the cleaning agent for cleaning, that is, the closed group cleaning agent is poured into the cleaning machine, the cleaning machine is connected to the oil pipeline of the engine, the gasoline pump is disconnected, the engine is started, and the idle speed is more than 15 minutes until the cleaning agent is used up.

Cleaning the fuel injector, there is no certain mileage, it depends on the working condition of the engine. Some cars may be buried for about 40,000 kilometers to be cleaned, some cars may be cleaned for 80,000 kilometers, and some cars may not need to be cleaned for 100,000 kilometers. Today's gasoline is much cleaner than before, and if you can keep the rpm higher when driving, you can have a long mileage to clean the fuel injectors.

Generally, the "non-disassembly cleaning method" can be used to clean the fuel injector, that is, to clean the oil circuit, and at the same time clean the oil injector, the fuel injector is also bent and washed.

Can the hanging bottle be cleaned to the oil circuit?

Whether it is a hanging bottle or not does not have much effect.

Hello friends. This one can be cleaned to the oil circuit.

Can the fuel injector be washed?

Hello friends. It can be washed off, but it is not clean.

How do you need to wash it, and do you remove it for cleaning?

Hello friends. The cleaning steps of the injector are as follows:1

Open the engine cover, lay the protective pad, and check the operation of the engine: whether there is vibration, abnormal noise, oil and water leakage, check whether all kinds of oil pipes, vacuum pipes, and engine wiring harnesses are aging and cracking; 2.Disconnect the fuel pump from power:

Open the fuel tank cap to relieve pressure, disconnect the gasoline pump or circuit, start the engine, consume the remaining gasoline in the oil pipe, and then turn off the engine; 3.Install special equipment (bottle) for dismantle-free cleaning: After mixing the cleaning liquid with gasoline, pour it into the storage bottle of the no-dismantling cleaning tool; 4.

There is no need to disassemble the special cleaning tool to connect: first find the fuel supply pipe joint of the fuel nozzle, disassemble and connect the fuel hose, and then connect; 5.Start the engine, clean the grease nipple:

No need to disassemble, open the valve of the special cleaning tool, start the engine to maintain idle speed, adjust the flow switch (the flow rate is not too large), and always pay attention to the operation of the engine; Branch resistance 6In the process of Qingmeng filial piety, the engine speed is increased to 1500 rpm every 2 minutes.

So much, I can't read it. It can be removed and cleaned.

Hello friends. It can be removed for cleaning.

The fuel injector is the main component to assist gasoline and diesel in atomization, and its characteristics can directly endanger the main energy performance and fuel consumption of the car. Many drivers go to clean the fuel injector on time, but many car buyers find that the fuel consumption of their vehicles is becoming more and more abnormally high after cleaning the fuel injector.

The fuel consumption of cleaning the injector is astounding.

It is normal for fuel consumption to increase after cleaning the injector. The first-class computer is able to manipulate the ignition advance angle, and the driving computer has a self-learning function. Before we clean it, because the fuel injector is blocked, the trip computer will automatically raise the ignition advance angle to maintain the actual effect of the fuel pump.

However, when the fuel injector is cleaned, the trip computer has not been adjusted independently in a short period of time, so the fuel pump may be operated according to the previous main parameters, which leads to the situation of increased fuel consumption. If this happens, you don't have to pay attention to it, and the driving computer will automatically adjust it back after a while.

Is the actual effect of 4S hanging bottle cleaning fuel injector good?

The actual effect is very good, and the fuel injector can be cleaned reasonably, but the overall actual effect is not as good as removing it immediately for cleaning. When the car finds abnormal flutter, acceleration fatigue, car engine fault lights on, fuel consumption rises, it is very likely to confirm that the car is blocked by the fuel injector, and when the car is blocked by the fuel injector, people need to go to the car 4S shop as soon as possible to solve the problem. Fuel injector blockage is generally caused by carbon deposits or gasoline and diesel residues, and everyone must cultivate good travel habits to prevent fuel injector blockage.

How often should the injector be cleaned in rotation?

Fuel injectors are not consumables, and they may not be replaced and cleaned frequently, and too much cleaning will cause premature damage to the fuel injectors. Generally speaking, 30,000 kilometers of Shangsun replied to the letter to check and clear once, if it is in good condition of the vehicle, gasoline and diesel refined oil is good, it can be cleared every 4-60,000 kilometers. Even if the injector is slightly clogged, there is no need to be overly anxious, because the residue can be sprayed away and ignited and melted away when the high-end acceleration is accelerated, and the car's performance can be restored, so it is proposed that the bubble kart highway.

When the fuel passes through the fuel injector, there is a gel inside the fuel injector, and there is insufficient combustion impurity carbon deposit on the outside, which makes the fuel injector too dirty.

The role of the fuel injector is to deliver the fuel precisely to the inside of the engine for combustion. A car fuel injector is a simple solenoid valve. When the solenoid coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is sprayed out at high speed through the annular gap between the shaft needle and the nozzle hole at the head of the needle valve, forming a mist shape, which is conducive to full combustion.

When the fuel injector fails, it will lead to an increase in carbon deposition in the engine, unstable idling, increased fuel consumption, weak acceleration, difficult starting, excessive emissions, etc., and in serious cases, it will cause the fuel injector to be blocked, and then damage the engine.

Reasons for higher fuel consumption:

1. Poor ignition: the spark plug gap is too large, and the ignition coil energy is not enough;

2. Poor atomization of fuel injector: the fuel pressure regulator is faulty, and the fuel pressure is too high;

3. Excessive carbon deposition in the engine: part of the gasoline sprayed is absorbed by carbon deposition;

4. Sensor failure: For example, the failure of the water temperature sensor will cause the engine to be mistaken for a cold state, and will always send out a fuel injection signal, resulting in high fuel consumption;

5. Oxygen sensor failure: the fuel correction will be invalid, the computer will always send out the signal of fuel injection, and the failure of the air flow meter will cause the incorrect air intake data.

When encountering a blocked fuel injector, pay attention to the following points;

First, don't coax the throttle with a big foot, especially if the fuel injector is blocked, which will cause the fuel injector to be completely damaged.

Second, the fault light is not good for a long time, and the fault light will be reported after a certain number of times, indicating that the car is not burning well before, which may be oil or oil deterioration and there is no good fuel to burn.

Thirdly, in the case that the oil circuit is not cleaned and not improved, cleaning the throttle will lead to an increase in air intake, a thin and leaky mixer, and the vehicle will shake at idle speed, and the throttle will be channeled.

Fourth, repairing a car does not mean that it will be good, and repairing it may aggravate problems in other places. This is normal and requires the use of elimination.

Fifth, in the case of poor combustion, shaking, and scurrying, the first thing to clean the oil circuit is, and not to rush to replace the accessories.

This is very easy to deal with, encounter such a fault code, after detection, it has been determined that the fuel injector is blocked, then the traditional way is to disassemble the fuel injector to replace, not to mention the replacement of the labor costs, we will say the reason for this, the nuclear shed we have to figure out why it will be blocked, will be after the replacement, to avoid the later blockage, after all, the replacement cost is very high, you replace the plug again, is it to consume a lot of costs.

There are two types of blockage, one is the external blockage caused by ash and carbon deposits on the outside of the fuel injector in the combustion chamber, and the other is the internal blockage caused by the oil in the oil circuit. Both of these blockages can be cleaned and unblocked by PNF-based additives. But be sure to use effective additives.

Don't wait for the car to have a problem before thinking about changing the parts, the cost outweighs the loss.

The fuel injector is an important component to help fuel atomization, and its performance directly affects the power performance and fuel consumption of the vehicle. Many car owners will regularly clean the fuel injector, but many car owners find that the fuel consumption of their car becomes abnormally high after cleaning the fuel injector, so do you know the reason why the fuel consumption of the fuel injector becomes high?

The fuel consumption of cleaning the injector is amazing

It is normal for fuel consumption to become higher after cleaning the fuel injector. First of all, the trip computer can control the amount of fuel injection, and the trip computer has a self-learning function. Before we clean it, due to the blockage of the fuel injector, the trip computer will automatically increase the fuel injection volume to maintain the fuel injection effect.

However, when the fuel injector is cleaned, the driving computer has not adjusted itself in a short time, so it still controls the fuel injection according to the original parameters, which leads to high fuel consumption. We don't need to pay attention to this situation, after a period of time, the driving computer will automatically adjust it.

Is it good to clean the fuel injector in 4s?

The effect is good, it can effectively clean the fuel injector, but the overall effect is not as good as directly removing it for cleaning. When the vehicle has abnormal shaking, weak acceleration, engine failure light on, and high fuel consumption, it is very likely to prove that the vehicle is blocked by the fuel injector, and we should go to the 4S shop as soon as possible to deal with it when the vehicle is blocked. Fuel injector blockage is generally caused by carbon deposition or fuel impurities, and we must develop good car habits to avoid fuel injector blockage.

How often should the injector be cleaned?

Fuel injectors are not consumables and do not need to be replaced frequently, and excessive cleaning will lead to early scrapping of fuel injectors. Generally speaking, it is checked and cleaned once every 30,000 kilometers, and if it is in good condition and good fuel and oil products, it can be cleaned every 4-60,000 kilometers. Even if the fuel injector is slightly blocked, there is no need to be too nervous, because when accelerating in high gear, impurities can be sprayed away and burned and dissolved, and the performance of the car can be restored to normal.

1. Turn off the engine, open the hood and hold it steady.

2. Unplug the oil pump safety of the vehicle to be cleaned.

3. Confirm that the flow control valve under the equipment is closed. Add a whole bottle of ultra-concentrated EFI cleaner to the fuel system tamper-free device.

4. Connect the external air source to the air and air interface on the equipment, and set the fuel pressure according to the technical requirements of the vehicle to be cleaned. The pressure of the cleaning fuel system is set at 200-300kPa (some say 450kPa).

5. Hang the equipment after adding cleaning agent and pressurizing it on the front machine cover of the vehicle to be cleaned.

6. For cars with oil return pipes, remove the oil return pipes and seal them, and open the fuel tank cover at the same time, or unplug the vacuum pipe of the pressure limiting valve and open the fuel tank cover.

7. Place a cloth under the oil man's pipe, slowly remove the oil inlet pipe, and connect it to the fuel pipe of the equipment.

8. Turn on the fuel flow switch under the equipment, check whether there is leakage, and start the engine of the vehicle to be cleaned after confirming that it is correct.

After a few minutes, after the cleaning is completed, remove the cloth under the inlet oil pipe, plug in the fuel insurance, restore the oil pipe of the vehicle to be cleaned, and check whether it is installed. At this time, start the cleaned vehicle to idle for 3-5 minutes, increase the speed to 2000 rpm, and check whether there is leakage in the oil pipe.
