Incorrect operation of the fuel system and low-quality fuel leads to pollution. Such pollution leads to a decrease in engine idling speed and a decrease in its power during operation.
Throttle cleaner, its purpose and application
We can say that the car engine is the heart of transport. Like a human organ, it needs prevention and care to function well. One of the vital procedures in engine maintenance is cleaning throttle valve. To successfully complete such an operation, a special tool is used, a cleaning liquid.
Liqui Moly is the most common cleaner in this series. The procedure helps to avoid unstable engine operation. Most often carried out in early generation cars. How often it will be necessary to perform the cleaning procedure depends largely on the correct operation of the fuel system.
In addition, incorrectly adjusted system valves can cause contamination, as gases from the piston chamber can return to the intake manifold. As a result, exhaust gas particles will settle on the walls of the channels.
Such pollution leads to a decrease in engine idling speed and a decrease in its power during operation. Therefore, there is an urgent need for a throttle cleaning procedure using liquid from Liqui Moly or other manufacturers.
Purifier
Liqui Moly Pro-Line is a throttle body cleaning fluid. Allows you to dissolve with subsequent removal of various deposits. Helps to get rid of particles of oil, resin, glue, etc. Great for cleaning injectors and other car engine parts.
From a number of the main properties of this liquid, the following can be distinguished:
- Effectively and quickly removes carbon deposits.
- There is no need to dismantle for the cleaning procedure.
- Quite simple and easy to use.
- Compatible with catalysts.
Good for cleaning intake manifolds, throttle bodies, axles. The tool has found its application both in injection systems and in carburetor systems. Provides good mobility of parts of the nodes, which allows the entire system to function correctly. The kit comes with a flexible probe, the use of which allows you to carry out preventive maintenance of nozzles and valves without dismantling them. Processing is done with the engine running. It is used only in cars that run on a gasoline engine.
Cleaning procedure
Throttle valve prevention is carried out by carrying out simple operations. This will require the following steps:
- It is necessary to remove the tube that provides evacuation of crankcase gases in the idle system. It also needs to be cleaned, since it is directly involved in fuel processes, and, accordingly, is subject to pollution.
- Next, you need to loosen the screw that secures the air filter pipe.
- Disconnect the fasteners located on the edges of the air filter cover.
- Then we clean the throttle body. To do this, we use a Liqui Moly cleaner or any other that is designed for such procedures.
- Disconnect the tube connected to the vacuum valve.
- Now we start the car engine so that it warms up. This is very important to increase the level of cleansing properties if you use a cleaning fluid.
- Carefully and carefully perform spraying in the following nodes:
- intake manifold. We process all the walls, spraying the product abundantly.
- Air supply channel. It is located near the throttle valve and provides an increase in the speed of the car's engine when it warms up. Through a hole in the shape of an ellipse, we penetrate inside. Also an important point. For its high-quality cleaning, you should not spare Liqui Moly in the process of spraying it. Otherwise, with poor-quality processing, dirt may remain. This will cause incorrect operation during warm-up and may require cleaning of the valve control mechanism itself. And this is a procedure that is different from the current one, since flushing is carried out by other means. Flush the entire system.
- Our next target is the tube on the intake manifold. We make it internal spraying. A rubber tube was connected to it and, as a rule, the junction is very dirty.
- Throttle assembly.
The cleaning effect is greatest when the engine is warm. Spray liberally on all listed nodes. Wait 5-7 minutes. This will allow particles of old dirt to exfoliate. After that, start the engine and, without turning it off, spray all the nodes again. Thus, you will get the maximum result from Liqui Moly.
Have you ever wondered why the motor reacts when you press the gas pedal? Thanks to the throttle valve, you can control the speed of the car. Like any machine mechanism, the throttle can become dirty. If this device is allowed to become excessively clogged, it will be more difficult for you to operate the machine. What to do if the throttle in your car is too clogged? Let's discuss this issue.
Appointment of a throttle cleaner
Every car owner understands that the engine is the heart of the car. Since the engine is constantly in operation, it is prone to contamination. That is why engine components need periodic cleaning. In particular, you need to clean the throttle body. For a successful operation, you need to use special tools to clean the throttle. There are also craftsmen who use quite exotic means for these purposes. But now there is no need to reinvent the wheel.
You can use liquids that are made specifically for cleaning the throttle. Thanks to these tools, the throttle valve will remain clean for a long time. That is, the next cleaning will need to be done not in a week, but after 50-60 thousand km. run. A special tool will not only protect the throttle from contamination, but will not have any detrimental effect on the element. This will be the case if everything is done correctly. The composition of cleaners includes a solvent and various kinds of additives, which together will give the desired result.
The leader in the production of auto chemicals, in particular, throttle cleaners, is the Liqui Moly brand. Of course, this company is not the only one of its kind, but still has established itself as the best. If the nearest automotive chemistry store did not have a product from the aforementioned manufacturer, you can purchase a regular carburetor spray. Some use WD-40 fluid or acetone. These products remove oil deposits and dirt, but can cause permanent damage to the throttle mechanism itself.
Application of throttle cleaner
Liqui Moly Pro Line- This is a liquid that is designed to clean the throttle body of a car. This tool is able to dissolve various kinds of deposits, after which they can be easily removed. Also, the cleaner will be able to cope with particles of oil, glue, resin and other compounds. As for the properties of such a liquid, they can be distinguished in the following points:
1. Fast and effective carbon removal.
2. For surface cleaning of the mechanism, it does not need to be dismantled.
3. The tool is very easy and convenient to use.
4. Excellent compatibility with catalysts.
Liqui Moly Pro-Line is suitable for cleaning not only throttles, but also axles, as well as intake manifolds. Special aerosols can also be used to clean the throttle. They need to be applied to the surface, left for 15 minutes and remove contamination.
Throttle Cleaning Procedure
It should also be said about the causes of pollution. Deposits appear on the throttle valve due to crankcase gases that carry oil dust. Gases enter the combustion chamber by accident, seeping through the valve cover of the ventilation system. The composition of crankcase gases includes the remains of the fuel mixture and its combustion products, as well as oil particles. It is the oil that creates a layer of pollution on the damper, it is this that should be removed.
Signs of an excessively dirty throttle body are as follows:
- the motor starts with failures;
RPMs at idle are uneven;
There is a failure during the transition from idling;
The car twitches during acceleration (at speeds below 15 km / h).
There are several ways to remove carbon deposits from the throttle. Some blow the cleaner into the mechanism while the engine is running. This option will not be very successful and gentle, and the cleaning composition itself is very undesirable to pour directly into the mechanism.
It is difficult to dismantle the assembly, but it is better to do so. Indeed, due to the excessive aggressiveness of the damper cleaners, plastic and rubber elements may suffer. It is in order to secure elements of rubber and plastic that everything needs to be disassembled. In no case should the cleaner be sprayed thoughtlessly, it should only be applied to the elements that are to be cleaned. If you use a cloth for cleaning, then you will not only make everything neater, but also more thorough. Throttle cleaning has a number of features:
Before using auto chemical goods, read the instructions for the product; when working, follow the mode established by the manufacturer. Always thoroughly dry the surface so that no threads or lint remain on the surface. If present, blow the surface with compressed air. Foreign elements must not be allowed to enter the system while the motor is running.
Do not resort to using a brush, which will remove a thin layer of molybdenum from the surface of the parts - this is highly undesirable, because this coating facilitates the movement of air. Be careful when cleaning - you can accidentally flood the throttle sensor, which cannot be dismantled.
It is highly advisable not to use cotton swabs, which will leave a lot of lint on the details. Cleaning the throttle valve is carried out as follows: Remove the tube that pumps out crankcase gases from the idle system. The tube must be cleaned, as it is directly involved in the combustion of fuel, which is subject to severe contamination.
Loosen the screw that secures the air filter fitting. Disconnect the fasteners that are located at the edges of the air filter cover. Then you can go directly to cleaning the throttle. Disconnect the tube that connects to the vacuum valve.
Start the engine and leave it running until it warms up. This is especially important because the throttle cleaner will perform its function more actively due to the temperature.
Gently treat the following nodes with the tool:
- intake manifold. Treat the walls by carefully spraying the cleaner on them
Air supply channel. It is located near the throttle and provides an increase in engine speed during warm-up. Air enters through an ellipsoidal hole. The channel must be very carefully cleaned so that no dirt remains in the system.
Next, clean the tube on the intake manifold. Treat it from within. A rubber tube goes to it, a lot of dirt accumulates at the attachment point. The valve assembly itself.
The best cleaning effect will be if the engine is preheated. Treat all the above knots liberally, then wait 5 to 7 minutes. Due to this, the particles of old dirt will quickly peel off. After that, start the engine again, process the nodes a second time, but just do not turn off the engine. So the result of processing will be the best.
Most car owners have noticed that over time, the engine speed begins to float, and difficulties appear when starting the engine. At idle, vibrations are felt, and the speed freezes. All these troubles can be associated with a dirty throttle or its channels. Due to dust and deposits, the damper cannot close properly. She jams and bites. In this case, it is recommended to clean the throttle assembly. Let's look at why they clean the throttle body, where the dirt comes from, how to do it yourself and what chemicals to use for this.
What it is?
Not every driver thoroughly knows the device of his car. Therefore, before you know why to clean the damper, you should figure out what it is.
Any internal combustion engine works due to the combustible mixture that enters the cylinders. Fuel burns in the chambers, due to which the pistons move and the crankshaft rotates. A spark is needed to ignite the mixture. But it is necessary not only to ignite the mixture, but also to maintain the normal combustion process in the future. Combustion requires an oxidizing agent - oxygen. When air and gasoline are mixed, an effective mixture is obtained that ignites perfectly and burns inside the cylinders. The throttle assembly is used to supply air to the engine, as well as to regulate its amount. The reliability and stability of the internal combustion engine depends on it.
Types of dampers
Distinguish between mechanical and electromechanical throttle valves.
The first type is connected to the accelerator pedal directly, using a cable. When the driver presses it, the damper opens. Air will enter the collector, which is mixed with a combustible liquid. This is an outdated design, and it is practically not used on modern cars.
Modern cars use an electronically controlled damper. The control unit controls the mechanism, which receives information from various sensors and decides in which position to install the damper. The electronic throttle paired with the ECU provides optimal torque performance in any engine operating mode. This design of the throttle ensures safety and allows you to comply with environmental regulations.
Where is the dirt from?
In modern cars, a forced system is used. A closed system to reduce the amount of harmful emissions. During operation, oil vapors, as well as gases from the cylinders, fly out of the crankcase during operation (albeit in small volumes).
A pipe comes to the throttle that comes out. There is always a small concentration of oil mist. If the engine is high mileage, then the number of oil particles will increase. The damper will become more and more dirty. This will cause the throttle to "stick". Why clean the throttle body? To stabilize the operation of the motor in all its modes.
The air that enters the damper is by no means clean, as in the laboratory. It contains, in addition to dust, solid suspension and a lot of what the air filter could not hold. Part of the dust due to rarefaction will enter the engine, while the other will settle on the pipe and damper.
As a result, a mixture of oil and dust forms on the throttle, as well as on the walls of the intake manifold. After ten thousand kilometers, this raid can even disable the throttle assembly. Why clean the throttle body? To avoid the need to repair or replace the throttle assembly.
When should you clean?
Why it is necessary to carry out throttle prevention, we understand. But when will that moment come? Let's try to find out. There are several symptoms that directly indicate the need for damper service.
So, the first reason is poor starting of the motor. That's why they clean the throttle on the VAZ-2110. Often cleaning it turns out to solve the problem with the launch. The idle speed can also float - the tachometer needle jumps or irregularities in operation are heard. The need for cleaning is also reported by increased fuel consumption, loss of power. Naturally, many of these symptoms can also be indicative of other problems. But the purity of the throttle plays an important role in the operation of the motor.
You can visually determine the level of contamination. If there are no visible oil stains on the throttle, then the solution to the problem must be sought elsewhere. If the damper is covered in oil and dust, then it's time for it to be cleaned. Now it’s clear why they clean the throttle on the Kia Sid and many other cars.
How does the damper affect idle speed?
It's simple - it has two devices installed. This is a throttle position sensor, as well as an idle speed control. These elements make it possible to add a combustible mixture to the cylinders and help maintain the optimum speed of the crankshaft. If the damper is dirty, these sensors will not be able to provide reliable information - hence the unstable idling.
That's why you need to clean the throttle body. A clean mechanism is the key to stable operation of the power unit.
How do they clean at the service station?
Most car owners are aware of the throttle problem, but prefer to have their cars serviced at a service station. In any service there are people who do not really like to work. In this case, the damper is washed without dismantling. In this case, do not even touch the idle speed controller.
In fact, the cleaning work is considered completed, but there is no result - the problems remain the same. The best effect can be achieved with self-prevention. We already know why they clean the throttle body. Now we will learn how to do it yourself.
How to clean the damper correctly?
Regardless of the model and brand of the car, the algorithm of operation is the same. This requires a minimum set of tools. So, this is a screwdriver, wrenches, as well as special chemicals that are sold in any car dealership.
First of all, remove the air pipe, and then unscrew the air filter housing. Further, this entire structure is removed completely assembled. At this stage, you can check the rubber seals - they lose their elasticity over time. If so, they should be replaced.
The damper may have a mechanical link connecting it to the "gas" pedal drive. The traction must be removed - it is easily hooked and effortlessly laid aside. Then remove the throttle position sensor. After dismantling, remove the connectors from the sensors. The work requires accuracy - force is useless here. Why clean the throttle valve on the VAZ-2110? To make the motor run better. And if you show excessive force, you can break the sensors.
Remove the idle speed controller from the damper. It is usually fastened with screws, by unscrewing which, you can easily pull the element out of the assembly. The tunnel under this sensor is often full of dust and oil deposits.
You don’t need to clean the damper to a mirror shine - there is not much point in this. Outside, it will always be dirty. The main thing is to clean it from the inside. It is necessary to ensure that there is no visual trace at the point of contact of the damper with the body. When this edge is gone, cleaning can be considered complete. The process itself is carried out with an aerosol can or with a brush. After cleaning, it is recommended to dry the unit thoroughly. Then you can safely assemble the throttle assembly - the work is finished.
How often to do it?
We know why they clean the Cadillac throttle valve - a gasoline engine is installed there, which means, one way or another, the valve will be dirty and the engine will start to work unstably after a while.
Another important question is how often to clean? In fact, everything here is very individual. If the engine is running at high loads, then the cleaning procedure is carried out approximately every 40-50 thousand kilometers. If you drive more calmly, then it is recommended to look at the state of the damper after about 100 thousand kilometers. The problem may come earlier, so you should be guided by characteristics that have been listed above.
Cleaning products
Why they clean the throttle valve at the VAZ is very clear. What's the best way to clean it up? The modern market offers several options available:
- One of the most the best means considered an aerosol from Liqui Moly Drossel Klappen. The volume of the can is 400 milliliters. Estimated cost of the product - 520 rubles. Removes oil deposits, oxides and dirt.
- The Mannol cleaner for cleaning carburetors also works effectively. The liquid cleans oil and dirt well. The price is 215 rubles for 400 milliliters in the form of an aerosol.
You can also highlight the liquid from "Abro". This is a fairly high-quality cleaner that is suitable for both carburetors and throttle bodies.
The cost is from 200 to 240 rubles for a can with the same volume (400 milliliters). Reviews note the speed of the drug - within 10 minutes after application, all dirt is washed off the surface.
Finally
So, we found out why they clean the throttle valve on Ford Focus 3, on VAZ, Cadillac and other models and brands. This is a necessary procedure - dirty air and oil mist, sooner or later, can disrupt the normal operation of even the most reliable and flawless motor. By performing regular preventive maintenance, we will significantly extend the life of the engine.
During the operation of the vehicle, the throttle assembly inevitably becomes clogged and requires timely cleaning. With the active use of the vehicle, the throttle assembly is constantly exposed to crankcase gases, small dust particles and working fluids. As a result, the carburetor begins to function unstably. Therefore, it is necessary to diagnose and maintain the throttle assembly in a timely manner. According to most manufacturers, flushing the throttle should be carried out after a run of 50,000 km. In addition, it is necessary to carry out preventive maintenance in a timely manner, which involves partial disassembly and cleaning of the assembly. The throttle body may be cleaned prematurely when the vehicle is operated in difficult climatic conditions. In this case, obvious symptoms will indicate contamination of the throttle assembly.
Signs of contamination of the throttle assembly.
If the car's engine has a problem with the transition from high speed to idle, then the probable cause of this is contamination of the remote control. A striking example of throttle contamination is the case when, instead of a gradual return to the required speed, the torque drops rapidly and the engine stalls with characteristic sound accompaniments. At the same time, the car engine with great difficulty restores the necessary torque. If this malfunction occurs, it is necessary to promptly start cleaning the remote control. Flushing the throttle valve will save some of the funds for vehicle maintenance, and return the productivity of the internal combustion engine.
Another symptom indicating a malfunction of the throttle assembly is difficult starting of the motor system. As a rule, when the throttle is dirty, it becomes more difficult to start the engine cold. If the node is fairly clogged, the hot start of the internal combustion engine may also be disturbed. As a rule, when the throttle is dirty, you have to turn the starter for a long time, and you can notice the smell of gasoline from the exhaust system. If you open the damper by pressing the gas pedal, the car engine starts. In this case, it becomes necessary to diagnose the remote control.
Do-it-yourself throttle assembly cleaning technologies.
To carry out the work, we need the following materials and tools:
- Socket wrench 13.
- Standard screwdriver set.
- Composition for cleaning the carburetor.
One of the main safety requirements when performing work is a cold engine!
Stages of work.
1. The first step is to dismantle the plastic engine protection.
2. The next step is to remove the tank cap and loosen the clamps in order to reduce the pressure in the cooling system.
3. Now we dismantle the pipe ventilation conductor and perform visual diagnostics for traces of oil. If traces of working fluid are found in the air pipe, the narrow channel of the remote control is most likely clogged.
5. Dismantle the tank ventilation hose and remove the remote control cable.
6. Now it remains to unscrew the holders of the throttle assembly and clean the system with a special fluid.
7. After successful cleaning, we restore the system in the reverse order.
Cleaning the throttle assembly is a simple procedure that every vehicle owner can handle. High-quality cleaning of the damper will allow you to get rid of problems when starting the vehicle and restore the productivity of the car's propulsion system.
" you will learn, how to clean the damper, do-it-yourself throttle, naturally. The work is not dusty and does not require special skills and knowledge. Moreover, on our website we have already talked about this, last time.
It should be noted right away that there are no cardinal differences in the performance of this work on different VAZ models, the principle is the same - we remove the throttle assembly, take a special liquid and spray it onto the damper. In rare cases, you have to make more effort and rub the throttle with cotton swabs, or even a toothbrush.
As always, before proceeding, a few words about what a throttle valve (DZ) is, why it gets dirty and how to understand what is needed throttle body cleaning. Go...
What is a throttle valve?
throttle valve (DZ) - an integral part of the fuel system of a gasoline engine. The main task of the DZ is the dosage of the air supply that enters the cylinders to form a combustible mixture. The throttle is located after the air filter and before the intake manifold. Simply put, DZ is an air valve that regulates the air supply. When the throttle valve opens, excess pressure in the intake system disappears; when it closes, negative pressure is formed in the system. Each time you press on the gas pedal, the damper opens or closes, since the remote control is connected to the gas cable.
In what cases is it necessary to clean the throttle body?
Signs of a dirty throttle, as well as the need to clean the throttle:
- Bad engine start, ;
- Jerks while driving at low and medium speeds.
Causes of throttle body contamination:
- Air. Although it is filtered, it still contains dust.
- Oiling and crankcase gases. These two substances form an oily coating on the DZ, which prevents the normal operation of the throttle assembly. The damper starts to open and close poorly (bad response to the gas pedal).
How to flush the throttle valve VAZ 2114-2115
There are two types of cleaning - with and without removal. First way provides for the following points:
1. Disconnect the air filter corrugation, remove the pipes, as well as the adsorber pipe. The coolant pipes must be bolted or bent and clamped so that the coolant does not spill out.
3. After the throttle is removed, it is necessary to remove the sensors ( , ) and clean them.
4. Next, using WD-40 or a special carburetor cleaning fluid (for example, ABRO), we clean the DZ. This is done simply, it is necessary to apply the composition to the damper, as well as the inner surface of the throttle and let the special tool do its job. After a few minutes, everything will be clean, but if the result does not satisfy you, repeat the cleaning, you can use cotton swabs or a toothbrush.
Attention! Never use sharp metal objects!
5. Let the DZ dry, after which everything is assembled in the reverse order.
Second way provides for disconnecting the air corrugations and cleaning the throttle valve right on the spot. The principle is the same: the solution is sprayed from one side and the other side of the DZ (for this, you can turn the shutter by hand at the place where the cable is attached). I did not try the second method, because in my opinion it does not make it possible to clean the throttle valve in full, so I cannot advise this method or talk about the results of such cleaning.
When flushing the throttle valve, I recommend replacing the DZ gasket. Basically everything. You can finish the article about how to clean the throttle valve VAZ 2114. I think that the knowledge gained will be enough for you to repeat all the above steps on your own.
