What is a car throttle and how do you clean it?

What condition must the throttle valve of the car be cleaned?

How exactly should the throttle valve of a car be cleaned? With the hood removed, we can usually see the acceleration orange collapse valve. Find the location of the accelerator valve, find the most dense tube of the engine, a head, then a square box, the air cleaner cartridge and the other side behind the engine.

The throttle valve is located where the engine is connected to the tube. You can see that the throttle valve of some cars sprays the throttle valve with cleaning agent and then washes it with a cloth, or pours the cleaning agent on the cloth and leaves it dry under the throttle engine cover, you can see when the cover is removed, after finding the throttle, there are two ways to clean it.

Turn off the car and find the throttle position. For some special models, the accelerator must be matched after cleaning and communication can only be done via a dedicated computer. So, in this case, it is recommended that you do not clean yourself to nunnery so that you do not succeed in matching.

When we clean it carefully, the throttle can be completely cleaned like new. With a clean throttle, your car can work without any problems. It is located in the starting gas position, behind the air intake, and is connected to the air filter; After traveling about 200,000-30,000 km, the accelerator is cleaned once.

The accelerator can be removed and filled with a special cleaning agent. Most cars now use electronic throttle. If the exhaust velocity is unstable after cleaning the accelerator, the suction tube must remember the position of each pipe and should only be kept in good condition after cleaning and installation.

Do not disassemble when cleaning the accelerator valve. Clean the accelerator valve. Remove the clean passage of the throttle valve.

Usually, the air intake port is deflected into a single word for car wash and maintenance. All the owner's friends made these plans. The same applies to the cleaning of accelerator valves.

If it's dirty, it must be clean, but how do you clean it? You can go to a regular repair shop and ask a master for help. The accelerator is usually cleaned once above 10,000 km.

Some pilots don't often make plans to save money. Step on the pedal and here comes the problem! What is an Accelerator?

The accelerator is controlled by air.

1.Use a flathead screwdriver to loosen the metal clips of the air filter and the fastening screws of the throttle body, separating the air filter top cover from the throttle body.

2.It is best for two people to clean the electronic throttle, one is responsible for stepping on the throttle and the other is responsible for cleaning. Spray the carburetor cleaner onto a clean rag and wipe carefully with the rag.

3.After cleaning, see if the throttle valve is clean and can be opened and closed freely. The empty filter is then attached to the throttle body and a seal is made to ensure it is in place. Tighten the screws of the metal clip and if there are any sensor connectors, plug them back in again.

4.After cleaning the throttle, learn the throttle initialization.

When cleaning the throttle, pay attention: do not unplug the throttle position sensor plug of the automatic transmission car, it is on the throttle body, otherwise, you need to use the instrument to re-initialize the throttle pedal position; Be careful not to spray the carburetor cleaner onto the air filter sealing rubber ring of the throttle body, it will corrode the rubber ring and affect the sealing, do not spray the carburetor cleaner directly into the throttle valve when cleaning the throttle to prevent the hose from falling into the engine, the correct way is to spray the carburetor cleaner on a clean rag, and then wipe it carefully with a rag, the carburetor cleaner spray is strongly corrosive, it is best not to touch **.

Millions of car purchase subsidies.

1. Use a slotted driver to loosen the fastening screws of the metal clip of the air filter and the throttle body, so that the top cover of the air filter is separated from the throttle body.

2. It is best to have two people to clean the electronic throttle, one is responsible for stepping on the accelerator and the other is responsible for washing, spray the carburetor cleaner on a clean rag, and then wipe it carefully with a rag.

3. After the cleaning is completed, see if the throttle is wiped clean and whether it can be opened and closed freely. Then connect the air filter to the throttle body, connect it to ensure the seal, tighten the screws of the metal clip, and reinsert the sensor connector if there is one.

4. After the throttle is cleaned, the throttle initialization learning is carried out.

When cleaning the throttle, pay attention: do not unplug the throttle position sensor plug of the automatic transmission car, it is on the throttle body, otherwise, you need to use the instrument to re-initialize the throttle pedal position; Be careful not to spray the carburetor cleaner onto the air filter sealing rubber ring of the throttle body, it will corrode the rubber ring and affect the sealing, do not spray the carburetor cleaner directly into the throttle valve when cleaning the throttle to prevent the hose from falling into the engine, the correct way is to spray the carburetor cleaner on a clean rag, and then wipe it carefully with a rag, the carburetor cleaner spray is strongly corrosive, it is best not to touch **.

The specific method of self-cleaning of the electronic throttle valve is as follows.

Tools Raw materials: deerskin cloth or nanocloth, cotton swabs, cleaning agent: It is recommended to use a special cleaning agent for electronic throttle, do not use carburetor, carburetor is more corrosive, which will make the rubber parts age.

Steps: 1. Buy a bottle of carbon deposition cleaning agent from a reliable source;

2. Open the front cover, find the engine and the air filter, and loosen the hairpin screw near the side of the engine.

3. Spray the cleaning agent on the electronic throttle, wipe it with a deerskin cloth, repeat the operation, you can use a cotton swab to clean the parts that are not easy to wipe;

4. Turn the car key to the ON position and continue to wipe until the black substance inside is cleaned;

5. Dry for a while after wiping;

6. Finally, reinstall the air filter pipe hairpin and tighten it, OK, and the cleaning work is completed.

Precautions: 1. The card must be tightened tightly, and there should be no air leakage;

2. A bottle of cleaning agent can generally be used twice, because it has a certain corrosiveness, try not to get it;

3. After wiping, it needs to be dried for a while to avoid the residual cleaning agent burning in the engine when starting.

A dirty throttle can cause poor engine acceleration, unstable idling, and increased fuel consumption. The throttle valve is the most important part of the engine system of today's EFI truck, the upper part is the air filter, and the lower part is the engine block, which is the throat of the car engine. Whether the acceleration of the car is flexible or not is very related to the cleaning of the throttle.

Therefore, car owners should regularly go to the 4S store to check and clean the throttle and keep the throttle clean.

Cleaning the throttle valve is generally carried out as follows:

1. First of all, if there is a plastic heat shield cover on the engine, it needs to be removed first.

2. Remove the hood cover, and we can see the throttle under normal circumstances. There are some air lines around the throttle that need to be removed and the location of each line should be remembered.

3. After removing the air line on the throttle and fixing the screws on the throttle. It can be removed quickly with the right tools.

4. The side of the throttle valve close to the combustion chamber will generally be dirty, and there are traces of black carbon deposits that are the main parts we need to clean.

5. Cleaning the throttle is mainly to remove the carbon deposits on it, we can use special throttle cleaning liquid or chemical detergent. It should be noted here that the cleaning principle of this type of cleaning agent is to dissolve carbon deposits, and its composition is more harmful to the human body, so it is best to wear gloves and masks when cleaning.

6. Spray the detergent to the position where there is more carbon deposition on the throttle valve, and wait for it to dissolve the carbon deposition for about 5-10 minutes. Using a brush will speed up the removal of carbon deposits.

7. When we see that the stain on the throttle has been completely dissolved, we can use a clean towel to wipe off the detergent inside the throttle.

8. Install the clean throttle valve on the engine body according to the original position, and then install all the air pipelines to complete the whole process of cleaning the throttle. Once all the hardware is installed, we need to initialize the throttle.

It should be noted that: after the cleaning is completed, it must be in accordance with the procedure just disassembled, and the initialization of the throttle must be started after installation, and after the throttle is cleaned, the initialization is necessary, because when the computer adjusts the opening of the throttle, it has a memory function, because there was a blockage of sludge before, in order to ensure the amount of air intake, the computer will automatically adjust the opening of the throttle, so that the intake is in a normal state. Clean the throttle or go to the 4S shop, it will be done quickly.

How to clean the throttle valve of the carOperation steps:

1. Turn off the engine and remove the intake hose from the intake manifold;

2. Open the throttle valve to a suitable angle, extend the thin tube into the intake manifold and spray for 5-10 seconds;

3. Wipe the internal and external surfaces of the throttle valve and the carbon deposits and other stains in the recent pipe;

4. Blow dry the intake manifold with compressed air.

Remove the throttle with a hex screwdriver.

Cover the air intakes to avoid debris falling into the engine.

Spray the dirt with detergent.

Finally, let it dry naturally.

After the throttle is replaced, restart or redo the throttle mating after powering off.

How do you know when it's time to clean? Let me tell you a simple trick: all electronic throttle models, as long as the engine is not loaded, neutral, bang on the accelerator pedal for 3000 rpm, and then suddenly collect the oil, at this time pay attention to the tachometer pointer!

1. When the pointer falls rapidly to 1000 to 1200 rpm, the pointer will pause slightly and then fall.

Remove the plastic heat shield cover from the engine, note the location of the pipes, remove it, and then remove the throttle.

Put on a gloved mask, use a solvent to dissolve the carbon deposits, and dry with a towel after 1 2 minutes.

Idle operation for 2 to 3 minutes is fine.

Automobile throttle cleaning method: 1. First melt the carbon with throttle cleaning agent, gently push the plate open with your hand, and brush the gap with a toothbrush; 2. Clean the carbon deposits with carburetor cleaning agent; 3. Repeat several times until the original metallic color leaks out from the throttle.

If your car is idling unsteadily, then it may be because the throttle is dirty, and it's time to wash it. The throttle is like the sole of our shoes, if it is dirty, it will definitely be dirty, if you go to the 4S store to clean, you can't escape for two or three hundred yuan, and it may not be clean. In fact, the owner can DIY clean the throttle, and the operation is not as complicated as imagined.

How to wash: Spray the detergent and wipe it with a cloth, and after taking out the throttle, we can find that there are a lot of oil stains inside and outside the throttle, and a lot of dirt and impurities are adhered to it. Once you've sprayed the cleaner on the dirty area, it's time to wipe it down with a cloth carefully.

Don't be lazy when wiping, especially those crevices that tend to hide dirt and dirt. If the gap is too small, you can clean it with a cotton swab dipped in some detergent. As long as we wipe it carefully, the throttle can be completely cleaned, like new.

With a clean throttle, your car can "breathe" smoothly and freely. The throttle valve is removed for easy cleaning. Although it is a little troublesome to operate by yourself, it is better to clean thoroughly.

During the operation of the EFI engine, a small part of the exhaust gas generated by combustion in the cylinder will generate carbon deposits at the throttle body through the intake valve and intake pipe. In addition, after the air body passes through the air filter, especially the air filter that has been used for a long time, there will be impurities left in the throttle. These contaminants accumulate over time and take a long time.

When the engine is old and unstable at idle, pay attention to cleaning the throttle. Here's how to clean the throttle:1.

Use a flathead screwdriver to loosen the fastening screws of the air filter and the metal clips of the throttle body so that the top cover of the air filter is separated from the throttle body. 2.Keep the throttle closed, spray carburetor cleaner around the doors, and wipe carefully with a paper towel and a small plastic pad.

Check that the throttle valve is clean and can be opened and closed freely. The pin then attaches the empty filter to the throttle body, which is connected to the position to ensure a tight seal. Tighten the screws of the metal clamp.

4.Note: Do not pull out the throttle position sensor of the automatic transmission with a branch, it is on the throttle body; Otherwise, the position of the accelerator pedal needs to be reinitialized using the instrument; Be careful not to spray the carburetor cleaner on the air filter sealant of the throttle body, as this will corrode the rubber ring and affect the sealing performance.

Usually the throttle is cleaned once after driving about 2-30,000 kilometers, and the throttle can be disassembled and cleaned with a special cleaning agent, but the 4S shop or repair shop usually cleans it in the way of "hanging bottles", and the specific operation is as follows:

Detergent cleaning.

Turn on the engine, locate the air cleaner box, remove the tubing, and then remove the throttle. Then use a special cleaning agent or carburetor cleaner, spray it on the throttle, wait for the solvent to dissolve the carbon deposit, and then brush and dry it with a soft brush for 1-2 minutes, and the operation can be repeated. The whole cleaning process needs to be disassembled, sprayed, brushed, and reinstalled, which is more troublesome to operate, but the cleaning effect is good.

Hang the bottle. The cleaning agent is attached to the pressure device and the cleaning fluid is continuously sprayed through the infusion tube into the air intake. In order to ensure the cleaning effect, it needs to be carried out with the engine running at a constant speed.

Although it takes a long time, it is relatively simple to operate, but the effect is average, and it only has a certain effect on cleaning the intake tract, and the rear of the throttle is difficult to clean.

After cleaning the throttle, it is easy to have unstable idle speed and increased fuel consumption, which is generally caused by the fact that the throttle opening is not reset. As the throttle is squeezed by carbon deposits, the opening of the throttle will be expanded. After cleaning, if there is no reset, the throttle opening will remain in the same state as before carbon deposits, and the air intake will increase, resulting in unstable idling, high rev and increased fuel consumption of the engine.

Nowadays, most cars use electronic throttle, if the idle speed is unstable after cleaning the throttle, it is necessary to use a diagnostic instrument to connect and match the engine, or pull out the negative pole of the battery to idle for a few minutes, and initialize the throttle to resume normal idling; Some models use mechanical cable-pull throttle, for this kind of throttle, it can be restored after about 10 kilometers after cleaning the throttle.
