Why do you clean the fuel injector, clean the throttle, and the fuel consumption rises sharply

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.

Go to the repair shop and match it with a decoder, please click thank you.

And how often should the injector be cleaned? What happens if you don't wash it? Throttle valves are generally cleaned every 20,000 kilometers or so.

The injector is generally cleaned once every 2 years, 60 km. If you don't clean it all the time, it will lead to an increase in fuel consumption and a decrease in power. It is best to wash it regularly.

As one of the key components of the EFI engine, the work of the EFI engine will seriously affect the performance of the engine. A clogged nozzle can seriously affect the performance of a car. The cause of the blockage is that carbon deposits in the engine are deposited on the injectors, or the injector channels are clogged due to impurities in the fuel.

After a car has been driven for a while, a certain amount of deposits form in the fuel system. The formation of sediments is directly related to the fuel of the car: firstly, due to the colloids and impurities contained in the gasoline itself, or the dust and impurities brought in during storage and transportation, over time, sludge-like deposits are formed in the fuel tanks and inlet pipes of the car; Secondly, the unstable components in gasoline react at a certain temperature to form a gummy and resinous viscous substance.

When these sticky substances burn in injectors, intake valves, etc. , the sediment will turn into a hard carbon deposit. In addition, cars tend to be at low speed and idle due to urban traffic congestion, which will exacerbate the formation and accumulation of these deposits.

Sediment in the fuel system is very harmful. The sediment will block the needle valve and valve hole of the injector, affect the working performance of the precision parts of the EFI system, and lead to the decline of power performance; Deposits can form carbon deposits in the intake valves, leading to unstable engine idling, increased fuel consumption, and worsening exhaust emissions. Deposits can form hard carbon deposits on the top of the piston and cylinder head, which can easily cause failures such as engine vibration due to its high heat capacity and poor thermal conductivity. In addition, the service life of the three-way catalyst will be shortened.

The performance of the injectors plays a vital role in the power of each engine.

Due to poor fuel, the injector works poorly, resulting in serious carbon deposition in the cylinder; Accelerated wear of the cylinder barrel and piston rings leads to unstable idling, increased fuel consumption, weak acceleration, difficulty starting, and excessive emissions, which can completely clog the injectors and damage the engine.

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

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.

It is recommended that the throttle and fuel injector be cleaned once every six months. If it is not cleaned for a long time, it will cause clogging and damage to the parts. This results in greater repair costs. Causing machine failure.

Generally speaking, it has to be cleaned after about 20,000 kilometers, and the fuel injector can be washed once every two years. If you don't wash it, it is likely to cause your fuel consumption to increase when driving.

20,000 km. If you don't wash it, you may reduce the service life of the car, and it is also prone to some dangerous breakdowns.

The reason why the car washes the throttle and fuel injector is particularly fuel-efficient and the idle speed is also high is: the car does not re-match the throttle and fuel injector after washing.

The solution is: if the throttle and fuel injector do not match, you need to go to the 4S shop or repair shop of the car in time to re-match the computer, which can solve the situation of high fuel consumption and idle speed.

When the fuel injector and throttle of the car are used for tens of thousands of kilometers in the car, the throttle is more seriously dirty, and the fuel injector is blocked, then it is very necessary to clean the dirty throttle and fuel injector, which is very beneficial to the normal operation of the car engine.

This is the case in most cars after washing the throttle, and the computer needs to be rematched. You can go to 4S and do it with a computer, or you can match it manually at home.

Manual Matching Method:

First, screw the key to the power supply gear (computer self-test), and do not start the car, that is, the ignition state.

After standing for about 10 seconds, quickly press the accelerator pedal to the end, be sure to press it quickly to the end, and quickly lift the pedal after 15 seconds.

After that, close the key door, remove the key, and let it sit for about 15 seconds.

Start the car normally and the match is complete.

This is the manual matching method of most electronic throttle cars, which is basically universal, and the reason is to use the adaptive learning function of the computer.

If it is not ideal at once, it can be repeated several times.

The throttle valve is not installed in place, and the throttle valve is leaking.

How to manually match the cable-type throttle.

For the "never wash the throttle injector" such a point of view, some car owners are supportive, some car owners feel that this statement is ridiculous, so why don't wash the throttle injector?

In fact, the statement "don't wash the throttle injector" is wrong, the throttle and fuel injector need to be cleaned regularly, and the owner needs to follow the advice of professionals. The throttle is used to control the engine intake, and the fuel injector is to control the amount of fuel, if the throttle is dirty, it will directly affect the air intake, then the throttle will be sluggish, or there will be flap jams. Moreover, if the throttle is dirty and not cleaned in time, the fuel consumption of the car will also increase, and the vehicle will have unstable idling, shaking, and even difficulty in starting the car.

If the injector is dirty and not cleaned in time, the engine will also shake, and if the injector is damaged, it will also lead to a lack of cylinder in the engine. At the same time, the exhaust of the vehicle will also turn black, and the fuel consumption will also increase.

The cleaning effect of the throttle and fuel injector of the car is not very good. It depends mainly on whether the throttle is dirty or not, and whether the injector is clogged with carbon deposits. If the throttle is not dirty and the injector is not clogged with carbon deposits, then the throttle and injector are also normal.

If you wash it a hundred times, it will be useless and effective. Cleaning the fuel injector and throttle separately can save fuel and improve vehicle power, and the owner does not feel the cleaning effect obviously. Clean injectors, throttle valves, and three-action catalysts do not reduce carbon monoxide, hydrocarbons, and nitrogen oxides in exhaust emissions.

Cleaning the injector and throttle valve separately will exacerbate the contamination and clogging of the three-way catalyst, which can be counterproductive in severe cases. If your car is due to the vehicle idling shake after the throttle is dirty, or the idle shake after the air conditioner is turned on, the idle speed is unstable, or even the engine fault light is on, the effect and function of cleaning the throttle at this time is obvious! After the throttle matching study of cleaning, the engine idle speed was normal, the air conditioner was not shaking, and the engine fault light was not on.

For example, Toyota's throttle valve is too dirty and may not activate after disconnecting the battery.

The Toyota Camry had a couple of meetings because the throttle valve was too dirty. After disconnecting the battery, the computer data of the engine is directly restored to the factory value, and the throttle opening given by the engine computer is not suitable for the opening after the throttle is dirty, so the vehicle cannot be started, because Toyota can match and learn the throttle by cutting off the battery after cleaning the throttle. When the vehicle travels every 20,000 km; Feel that the fuel consumption of the vehicle increases and the power decreases; Before each vehicle exhaust condition test; It is recommended to clean the vehicle's fuel injectors, throttle valves, and three-way catalytic converter according to the above.

Effectively remove carbon deposits and colloids from the combustion chamber, throttle and intake manifold, so that the oil-gas mixing ratio can be restored to normal. Improve combustion, reduce fuel consumption, increase the effective power of the engine, and stabilize the idle speed. It is harmless to sensors and three-way catalysis, and non-corrosive to metal and rubber products.

The inner wall of the air intake system forms an effective protective film to ensure the normal operation of all components and reduce fuel consumption. As a result, after a power outage, the previously stored values in the engine computer disappear and the new values do not fit the current engine state, causing the engine to malfunction or be difficult to start. When the injector is clogged by carbon deposits, the amount of fuel injected is inaccurate, resulting in engine shaking and lack of fire failure, causing the engine fault light to illuminate.

At this point, the engine injectors need to be cleaned. The cleaning of the injector includes non-disassembly and cleaning and disassembly and cleaning. Hanging bottles are generally used for disassembly and cleaning.

If the injector is removed and cleaned, it will be cleaned again. In general, after cleaning the injectors, the engine will not shake and lack fire, accelerate faster, and of course, it will be more fuel-efficient.

I think it plays a big role because the throttle and fuel injector are prone to carbon deposits, which affects the power of the engine.

The effect is very large. Because this fuel injector can make Xiamen a little cleaner, it can also enhance the life of the car.

I don't think it's big, because now it's all EFI trucks, the throttle generally doesn't have carbon deposits, and the probability of carbon deposits from the fuel injector is very small.

Cleaning the solar term jujube hunger door and cleaning the fuel injector are not the same thing.

After the throttle is dirty, it affects the air intake, the throttle response is sluggish or the flap is jammed, etc., what kind of fault phenomenon will the car have: difficulty in starting, especially the most obvious cold car, unstable idling, shaking, increased fuel consumption, slow response of the fuel pedal and other phenomena.

After cleaning, it is necessary to make a match with the engine control unit Xinque, re-remember the angle of the opening position, and the control of the air intake can determine the fuel injection volume of the fuel injector.

The fuel is not completely clean, it will contain some impurities, then these impurities in the pipeline of our fuel supply system, will slowly form some substances that block our fuel supply pipeline.

Especially in our injectors, which need to provide atomization effect to fuel, because our early oil nozzle needs to provide atomization effect, so the oil hole of the oil nozzle is very small, so the smaller oil hole is easy to be blocked by impurities.

Therefore, regularly replacing the fuel filter in our fuel supply system and cleaning the fuel common rail of our injector is a better maintenance method for our fuel supply system.
