10,000 km maintenance Do direct injection engines need to add fuel injection cleaners?

Engine maintenance needs to comprehensively remove carbon deposits and sludge from blocked oil circuits, fuel injectors, intake valves, etc., and different products can be used for in-depth maintenance of carbon deposits in different parts. If the direct-injection engine has never been maintained for more than 10,000 kilometers, it is recommended to use fuel injector cleaning agent. Inside the engine, it is recommended to use engine anti-wear protector for the maintenance of the oil tank.

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.

Third, in the case that the oil circuit is not cleaned and improved, cleaning the throttle will lead to increased air intake, thinning of the mixer, and the vehicle will shake at idle, 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 the 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, we have to first 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 cost.

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.

About 30,000 kilometers to clean the fuel injector, the cleaning method is: 1. Disconnect the power supply of the automobile fuel pump; 2. Connect the special tool for disassembly-free cleaning; 3. Open the valve of the special tool for disassembly-free cleaning, start the engine to keep idling, and adjust the flow switch; 4. Increase the engine speed every 2 minutes until the cleaning agent is completely exhausted; 5. Release the pressure of the no-dismantle cleaning tool system; 6. Start the engine and check whether there is any leakage in the oil circuit, and test the vehicle to ensure that it is normal.

It depends on your driving habits, road conditions, and fuel quality, and it should be cleaned once every 5-60,000 kilometers.

It cannot be used and must be replaced, because the cleaning agent and engine oil will be chemically reflected, resulting in the decline of various indicators of the engine oil and easy to cause abnormal damage to the engine.

Aside from the dosage and talking about the efficacy, it is a hooligan, too much will definitely have an impact!

Engine oil is meant to be lubricated and cleaned, not so delicate! Although the chemical composition of the fuel injector is not clear, it is less likely to have a chemical reaction with the oil (easy to corrode), mainly depending on the amount of water, which will emulsify the oil.

Suggestion - use the car normally for two days, then pull out the oil dipstick to see the oil status, there is no problem OK.

If the amount is small, it is okay, but if the amount is too much, it is not good, after all, the detergent and the oil are repulsive and cannot be mixed, it is best to change the oil again

Did you add it by mistake when you added the engine oil, just put the oil out, it's fine.

The oil must be drained and refilled.

There is no harm to the engine, the fuel injector cleaner is originally to clean the engine, and it is often recommended to clean the engine for maintenance, this ingredient is the same, and it is useful for cleaning the engine.

Start it to change the oil again, you have to change it.

It's a little bit harmful, it's like people drinking the wrong water and taking 7-Up for Sprite, it's not a big problem!

It needs to be cleaned, and the specific maintenance items are related to.

1. The engine cleaning agent contains special decontamination ingredients, which can effectively dissolve and clean the gum, oil sludge and carbon deposits in the engine oil circulation system, and know it with the old engine oil discharge mold, so as to improve the lubrication efficiency;

2. Disability inhibits the generation of acidic substances inside the engine and protects the generation of acidic substances inside the engine;

3. Protect the engine from corrosion, restore the engine power, reduce fuel consumption and engine wear, prolong the service life of the engine, and make the engine lubrication system smooth and quiet.

The engine fuel injector should be cleaned regularly, this is to avoid too much carbon deposition in the car engine, which will lead to insufficient power and fuel consumption of the car.

It can improve the fuel injection effect, save fuel, improve power and reduce the failure rate.

Clean the injector regularly because the grease is not clean or the oil is not good.
