Do I have to clean the throttle every maintenance? How to clean it?

The mileage of normal throttle cleaning varies from car to car. Some suggest cleaning once every 2-4w kilometers, and some even do not necessarily need cleaning after 6w! The key depends on the phenomenon!

Why is the throttle dirty: 1. The fuel nozzle of the EFI vehicle is located in the intake manifold. When the engine is turned off, the sprayed gasoline vapor will condense on the intake manifold and throttle. When it is started again, the trace dust in the air will attach to the gasoline condensate of the throttle valve and gradually become dirty.

2. Due to the demand of environmental protection, a small amount of oil vapor discharged from the engine crankcase forced ventilation system will be injected into the throttle after passing through the oil-gas separator, and some oil vapor will adhere to the throttle at this time, resulting in long-term dirty throttle.

Consequence of dirty throttle: 1. Increased fuel consumption: The throttle valve controls the air intake of the engine, and it will be affected when the throttle valve is dirty. When the flow detected by the air flow sensor at the air inlet deviates from the actual air intake of the throttle, it will affect the fuel injection calculation of the EFI system and increase the fuel consumption.

2. When the calculated air intake deviation is within a certain range, the engine gear driving computer can calculate and compensate the deviation, but when the deviation is too large to compensate, the automobile will appear: increased fuel consumption, difficult starting, unstable idle speed, engine jitter and other phenomena. At this time, you need to clean the throttle.

How to clean it: Throttle is a part of daily maintenance, and it is very simple to remove. Generally, after disconnecting the negative electrode of the battery, remove the air inlet pipe and use the wrench number. 10 to disassemble it After disassembling, spray it with special cleaning agent. After cleaning, the throttle must be matched and reset, otherwise the engine will automatically match after driving for a period of time.

Hello, tens of thousands of kilometers don't need to be cleaned often. It should not be called maintenance, it should be called cleaning. Remove it after the intake pipe, spray it with carburetor cleaner or head water, wipe it and blow it. Some models consume a little oil after cleaning, and it will be fine to run for a while. Computers have a self-learning process. After cleaning up some models, it is very simple to re-match the computer to clear the learning value.

Is it necessary to clean the throttle regularly? First of all, tell my friends what they are most concerned about: it is meaningful to clean the throttle regularly.

I'll tell you why later, and what the throttle is and what it does. I think I wrote very well. Remember to give me a look after reading it. I spent a lot of time writing it.

During the long-term use of the engine, carbon deposits will inevitably accumulate around the throttle. Dirty throttle will affect ECU's control of throttle opening, and then affect idle speed, causing jitter and other problems. More seriously, if a carbon step is formed, the throttle will get stuck, which may lead to further failure and flameout.

If there is less dirt on the throttle, the driving computer of the engine can adjust the air intake by itself. It's no use washing at this time, it's a waste of money.

When there are a lot of dirty things in the throttle, it may be a little blocked, resulting in inaccurate intake control, unstable idle speed, poor acceleration and power, and high fuel consumption. That's because the air intake has decreased. At this time, it is very necessary for us to wash it.

Of course, some friends will know this very well, and it is ok to clean it yourself, but if you don't understand, you should find a professional institution and person.

Generally, when the engine is difficult to start, wobbles and the speed is unstable when idling, it is necessary to clean the throttle valve, intake manifold, fuel injector and other components when a large amount of carbon deposit is found through inspection.

How often should the throttle be cleaned? Why is it dirty? Generally, it should be washed every 20,000 kilometers. If the pollution is serious, you can wash it in advance.

Generally speaking, it is not reliable if you are asked if you want to spend hundreds of dollars to clean the throttle every time you go to maintain your car. It's not too late to think about this problem when our car runs about 20 thousand kilometers.

Because of the ventilation function of engine crankcase and the function of activated carbon canister solenoid valve, a small amount of gasoline vapor will be brought to the throttle, and the oil and gasoline attached to the throttle will continue to attach to dust.

How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and so on.

Dirty oil, long-term non-replacement of air filter and poor quality of air filter will aggravate the dirtiness of throttle valve.

What the hell is a throttle? Throttle is a controllable valve, which is used to control air to enter the engine. Above (or in front of) it is an air filter, and below it is an engine block.

The position of the throttle valve is equivalent to the "throat" of the car. After the air enters the intake pipe, it needs to pass through the throttle valve, and then it is mixed with gasoline to form a combustible mixture, which participates in combustion and does work.

Electronic throttle system is widely used in modern cars.

In layman's terms, this air filter is like a mask you wear, which is responsible for filtering gas. The throttle is like your nose or mouth. You can control the amount of air entering by closing and opening it. Then sometimes you need to take a deep breath when you exercise, and sometimes you don't.

Summary: Throttles are like our mouths or noses. It controls the amount of air entering the body by expanding and contracting. Regular cleaning is beneficial. It is usually washed once every 20,000 kilometers. If the pollution is serious, it can be cleaned in advance.

In fact, there is no need to clean the throttle of our car engine every time we maintain it, because the throttle of our car engine is not so dirty.

I suggest you clean the throttle valve. It is the most cost-effective period to clean the throttle as far as possible at a distance of more than 30 thousand kilometers, and it is also a good cleaning cycle for the throttle.

But everyone's car environment is different, so the impact on our throttle is different. The environmental factors in the use area and the driver's habits have a great influence on the dirtiness of our throttle.

So I suggest you try to pass the inspection of the throttle before deciding whether to clean it.

If we compare our human nose to the accelerator of a car, then the masks we wear are equivalent to the air filters on the car. The air filter is used to filter air dust impurities entering the engine through the throttle.

If the air filter is not replaced for a long time, or the place where it is used is particularly dusty, more dust and sundries will enter the throttle through the air filter and slowly attach to our throttle. In this case, we need to clean the accelerator in advance.

Of course, our most accurate method is inspection. When the throttle is dirty, it even affects the idle speed of our engine and makes the engine slightly shake, then we need to clean the throttle.

Simply put, it is not necessary to clean the throttle every time, unless the use environment is too bad, such as driving in a high dust and high pollution environment for a long time, then clean it simultaneously every time. There are many kinds of throttles, so it is generally recommended to go to a professional garage to find a professional master to clean them.

As for how to clean, here are a few points that can be supervised even by a professional master. First, it is necessary to use a special cleaning agent for the throttle valve, mainly to protect parts, and chemical oil cleaning is a bit corrosive; Second, if the carbon deposit is not so serious, don't take it apart for cleaning, especially when the new car has just entered the maintenance period. Mainly unnecessary, frequent disassembly is not good for parts. And some models can't be disassembled; Thirdly, if the car is old and the throttle has never been cleaned, the risk of cleaning is greater, because it is very likely that the throttle valve body has been irreversibly worn, which may lead to unstable idle speed and increased fuel consumption after cleaning, and finally only accessories can be replaced; Fourth, it is the problem of collocation. Many electronic throttles need computer matching. If it is a common model, it is generally not a big problem. These repair shops will know better.

Last but not least, a car with a clear throttle will be unstable at first, even if it is well matched. This is a normal phenomenon, so after a period of normal driving, it is beneficial to learn and adapt to the body computer system.
