Reasons why engine fuel injectors should be cleaned regularly

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.

Hello, the fuel injector is injected, if it is not washed for a long time, it is easy to cause blockage, resulting in abnormal fuel injection

Hello! The engine will be generated.

Carbon deposits. But to a certain extent, carbon deposits are blocked.

Fuel injectors. As a result, the atomization of the fuel injector is not good, and the efficiency is reduced, so it is recommended to clean it regularly!

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.

The fuel injector can generally be cleaned once every 2 years or 5 to 80,000 kilometers, depending on the quality of gasoline in the area where the vehicle is used.

There are two ways to inject fuel nozzles: one is disassembly and cleaning, and the other is disassembly and cleaning.

It is necessary to clean the engine fuel injector, the engine fuel injector is dirty, which will lead to an increase in fuel consumption of the vehicle, insufficient power, idle shake and a series of failures, I personally feel that the biggest impact is the increase in fuel consumption, after all, the current oil price is so expensive, or a little distressed. It is recommended that it is necessary to clean the fuel injector regularly, and it is also necessary to go to a large gas station to refuel. Because the quality of gasoline is not good, it is a bit more than worth the loss if the fuel injector is deposited or damaged.

If the fuel injector is rotten and the rubber is transported, it does not need to be cleaned under no abnormal conditions, or it is cleaned for about 5 to 80,000 kilometers.

As one of the key components of the EFI engine, the fuel injector will seriously affect the performance of the engine. A clogged fuel injector can seriously affect the performance of the car. The cause of the blockage is due to the deposit of carbon in the engine on the fuel injector, or due to impurities in the fuel that block the injector path.

After the car has been driven for a while, a certain amount of deposits form in the fuel system.

The formation of sediment is directly related to the fuel of the car: first of all, the gasoline itself contains gums, impurities, or dust and impurities brought in during storage and transportation, etc., which accumulate over time to form sludge-like deposits in the fuel tank and inlet pipe of the car.

The second is due to the reaction of the unstable components in gasoline at a certain temperature, forming a gummy and resinous viscous. These sticky substances are found in areas such as fuel injectors and intake valves, and when burned, the deposits become hard deposits.

The fuel injector does not need to be cleaned under no abnormal conditions, or it can be cleaned once for about 5 to 80,000 kilometers.

Clogged injector can lead to:

1. It affects the working performance of the precision parts of the electronic injection system, resulting in a decrease in power performance.

2. The sediment will form a late round carbon in the intake valve, resulting in its loose closure, resulting in unstable engine idling, increased fuel consumption and deterioration of exhaust emissions.

3. The sediment will form a hard carbon deposit on the piston top and cylinder head, which is easy to cause engine knocking and other faults due to the high heat capacity and poor thermal conductivity of the carbon deposit.

4. In addition, it will shorten the life of the three-way catalytic converter.

Therefore, Xun Zheng should clean the fuel injector to maintain the condition of the car.

Reasons why the fuel injector of the car should be cleaned frequently:

The quality of the fuel injector plays a fundamental role in the power play of each engine. Poor fuel will lead to ineffective injectors, serious carbon deposition in the cylinder, accelerated wear of cylinder barrel and piston rings, resulting in unstable idling, increased fuel consumption, weak acceleration, difficult start-up and excessive emissions;

In serious cases, it will completely block the fuel injector and damage the engine. Therefore, it is necessary to clean the fuel injector regularly, and not cleaning the nozzle for a long time or cleaning the nozzle frequently will cause bad effects.

Introduction: Many car owners should find that if they don't wash their cars for a long time, there will be a lot of dust on the surface of the car. Especially on rainy days, the dust becomes even more severe.

In fact, in addition to the appearance of the car, the fuel injector of the car also needs to be cleaned. Do you know why, the fuel injector of the car must be cleaned regularly? <>

Many car owners may find that if the car is not cleaned for a long time, there will be a lot of dust on it. The reason why this is so is that the outside is relatively dirty, and there will be some pollutants attached to the surface of the car. In addition to the appearance of the car that needs to be cleaned, the fuel injector of the car should also be cleaned regularly, because only in this way can the engine of the car be better protected.

Once the fuel injector is not cleaned for a long time, it may have a particularly large impact on the engine, and the wear and tear of the engine will be more serious at this time, and even lead to some engine failures. <>

In addition to maintaining the engine, regular cleaning of the fuel injector can also reduce the fuel consumption of the car. Because the car may have some deposits and even carbon deposits during long-term use. If you don't clean the fuel injector at this time, it may increase the fuel consumption of the car.

There may even be a lack of power in the car, so once this situation occurs, it may take a lot of money to repair, so it is very important to clean the fuel injector regularly. <>

After reading the introduction, I believe you also know why you should regularly clean the fuel injector of your car. If you don't clean it, it may cause a lot of damage to the car, and over time, all parts of the car or the combustion rate and parts of the car will be affected. Then everyone must want to drive for a long time after buying a car, and changing the car casually is very wasteful, and it is also not conducive to environmental protection.

Therefore, if you want to extend the service life of the car, you must maintain and maintain the vehicle regularly. However, if it is washed too often, it may also cause some damage to the car.

This results in a drop in power and unstable idling.

This will lead to the blockage and adhesion of the fuel injector, resulting in fuel injection leakage, poor atomization, or even no fuel injection, resulting in increased fuel consumption, increased sail loading, decreased engine power, unstable idling, poor acceleration and cold start difficulties, etc., these problems can be solved after cleaning.

Cleaning is harmless, cleaning can improve the air intake and fuel injection accuracy, but also improve the efficiency of the fuel, prolong the service life of the engine, the benefit is that the engine sound becomes better, fuel consumption has decreased, exhaust gas is reduced. If you do not clean the throttle and fuel injector for a long time, it will cause excessive dirtiness, such as weak acceleration, loud noise, fuel consumption, and car shaking, so it is necessary to clean it regularly.

This is because the fuel injector is very important, if the zero gear of the hood is not cleaned for a long time, it is likely to be blocked, and there may be very serious carbon deposits, and then it will also affect the performance of the engine before the stupidity, which will affect the normal safe driving.

This is done so that the oil nozzle can be used normally, which can avoid clogging and better ensure the cleanliness of the fuel system.

This is because the injector may become clogged, and if it is not cleaned regularly, it may cause damage to the parts.

In order to be able to use the fuel injector normally, the car will not be stuck while driving, and the fuel system will be kept clean.

How often should the injector be cleaned?

There is no fixed answer to how long the injector should be cleaned. The fuel injector is not a vulnerable part, and if the vehicle is idle and starts normally, it generally does not need to be cleaned. At the same time, the fuel injector is also a precision product, including multi-point EFI, single-point EFI, direct injection and other different types.

It is recommended to use something similar to additives to maintain the daily cleaning of the fuel injector when using it normally, once the disassembly and cleaning operation is improper, it is likely to have a little impact on the future assembly.

The advice given by the maintenance master I know is: if you love the car and are willing to consume, then it can be cleaned once every 20,000 kilometers, and the average car owner can search once for 30,000 kilometers. If the car is in good condition and the fuel quality is good, then it can be extended to 4 to 60,000 kilometers to be cleaned.

How much does it cost to clean the injector once?

If you go to the 4S shop, then they will generally recommend that you do a full set, that is, car oil cleaning, basically using the way of hanging bottles, hanging a bottle-shaped tool above the engine, and then pouring the detergent into the bottled tool, through the conduit into the engine, to achieve the purpose of cleaning the digital calendar carbon deposit, **at about 1000 yuan,**for reference only. If it is an external repair shop to clean the fuel injector alone, it will be much cheaper, generally around 200-300 yuan.

How to clean the fuel injector?

Hang the bottle" in the way of cleaning.

This method is simple and easy to operate, as long as the appropriate cleaning agent is snapped into the special equipment, the connecting pipe is connected to the air inlet and the oil inlet pipe according to the regulations, and then the engine runs for 20 minutes.

Wash-free cleaning.

This method uses the pressure of the engine's original system and the circulation network to clean the carbon deposits in the cylinder with cleaning agent instead of oil combustion, and then discharges it by the exhaust system. Although this method is simple, there are too many varieties of cleaning agents, and the specifications are different, if it is a poor quality cleaning agent, it will be easy to damage the piston, exhaust valve and cylinder wall during the cleaning process because of the different calorific value, and also have certain damage to the nozzle and sealing ring of the injector and the three-way catalytic converter.

Ultrasonic cleaning method.

This is now the most common model and the cleaning effect is also relatively good, and the fuel injector needs to be removed.
