How to clean the throttle of the van

Question 1: How to clean the throttle of the van? First of all, if there is a plastic heat shield on the engine, it needs to be removed first. When the hood is removed, we can usually see the throttle. There are some air pipes around the throttle. We need to remove these pipes and remember their positions clearly. After removing the air line on the throttle, we can remove the whole throttle. Trent's throttle is fixed on the engine block with four bolts, and we can quickly remove it with suitable tools. The side of the throttle near the combustion chamber is generally dirty with black carbon deposits, which is the main part we want to clean. Cleaning the throttle is mainly to remove carbon deposits on it. We can use special throttle washer fluid or cleaner. It should be noted here that the cleaning principle of this cleaning agent is to dissolve carbon deposit, and its composition is harmful to human body. It is best to wear gloves and masks when cleaning. Spray the cleaner to the position with more carbon deposits on the throttle, and wait for about 5- 10 minutes to dissolve the carbon deposits. Using brushes can speed up the removal of carbon deposits. When we see that the stain on the accelerator has completely dissolved, we can wipe the detergent inside the accelerator with a clean towel. The picture above shows the clean back of the throttle, with no traces of carbon deposition. Install the cleaned throttle valve on the machine body according to the original position, and then install all air pipes to complete the whole process of cleaning the throttle valve. After all the hardware is installed, we need to initialize throttle.

Question 2: How to clean the throttle of the van? The probability of throttle valve is only 5%. Please check other problems and clean the oil head. The operation of the idle valve is very simple. Just buy a can of carburetor cleaner and spray it. Be careful not to buy fakes! The fake one won't come off.

Question 3: What are the benefits of cleaning the throttle of the van? Clean up carbon deposit, improve intake and injection accuracy, improve fuel efficiency and prolong engine life. The advantage is that the engine sounds good, the fuel consumption is reduced and the exhaust gas is reduced.

Question 4: The van cleaned the throttle valve. How to deal with unstable idle speed? After cleaning the throttle valve, the most direct manifestation of not re-matching is that there will be high idle speed, and some engines will accelerate to 1500 r/min or even higher, with high fuel consumption and excessive emissions. The exhaust pipe will emit black smoke when accelerating.

Question 5: Where are the solar terms of minivan and Wuling Light? How to clean them? How many solar terms are there? I don't understand the throttle: it is a controllable valve to control air entering the engine. After entering the intake pipe, it is mixed with gasoline (the design mixing parts of different models of cars are different) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in today's EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.

The throttle can be removed, but the sealed part of the air inlet must be cleaned, and the idling motor can only be cleaned after it is removed. There are advantages and disadvantages of cleaning the nozzle by disassembly. Generally speaking, the maintenance station suggests disassembling and washing to prevent other wastes, such as replacing the sealing ring or touching other gaskets for installation, or delaying the owner's time when disassembling.

How to clean and prevent it should be removed and washed! Correct some misunderstanding of throttle cleaning!

The main cause of throttle scaling is oil and gas, followed by particles and moisture in the air. In other words, using qualified air filter and removing the crankcase ventilation pipe will slow down the scaling speed of throttle valve. Crankcase built-in crankshaft

throttle valve

The lower part is connected with the oil bottom, and its working temperature is about 100 ~ 180. Oil will volatilize when used. The longer it takes, the higher the temperature and the stronger the volatilization. In addition, the compressed gas in the cylinder will squeeze into the crankcase through the gap of the piston ring, so there must be a channel for the gas to escape, otherwise the oil bottom will form a positive pressure (see the related article in Nightcrawler for details). The reason why the crankcase ventilation pipe is connected to the throttle valve is the requirement of environmental protection on the one hand, and the gas is pumped out of the crankcase by using the negative pressure of intake air on the other hand. When the oily steam reaches the intake pipe and cools, the oil in it will condense on the intake and throttle valve, and then the carbon deposit in the steam will also be deposited on these parts. Because the gap where the throttle valve is opened has the largest air flow, small space and low gas temperature, this part is the easiest to condense.

Therefore, how long the throttle will be dirty depends on the quality of the air filter, the brand and quality of the engine oil, the condition of the driving section, the temperature, the working temperature of the engine, driving habits and so on. Even for individuals, it is impossible to determine the time to clean the throttle with a fixed number of kilometers. The interval between cleaning the throttle valve for the first time in a new car is the longest. Because of the constant condensation of oil and gas in the crankcase ventilation pipe and air inlet, the cleaning frequency will increase, and different weather conditions will also affect the dirty speed of the throttle valve. ......

Edit the cleaning of throttle valve in this paragraph.

Throttle is the most important component in today's EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the accelerator should be removed for cleaning is the focus of discussion among car owners.

Pay attention to this question:

If there is too much sludge in the accelerator, it may cause poor engine acceleration and increase fuel consumption, which is a big worry for the owner. What should I do if the throttle is dirty? As long as you clean it, you can get it in the 4S shop quickly, but don't you go to the 4S shop every time? Actually, you don't have to. You can handle it yourself. Just don't forget to initialize.

When cleaning the throttle valve, first remove the intake throat to expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can hold a rag and scrub it carefully where your hands can't reach it.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled for cleaning. There are advantages and disadvantages of cleaning nozzles by borrowing and disassembling. Generally speaking, the maintenance station suggests disassembling and washing, which can prevent other unnecessary waste, such as replacing the sealing ring after disassembling, installing other gaskets, or delaying the owner's time because of oil and gas leakage when disassembling. [ 1]

After cleaning, the throttle will be initialized according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage in the past. In order to ensure the air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.

But there is no sludge blockage after cleaning. If the throttle valve remains open as before ... >>

Question 6: How much does it cost to clean the throttle of the van? About 20 years old

Question 7: Where is the throttle of Wuling van? When the passenger seat is turned on, the air filter hose is connected by removing the hose to start the engine, cleaning it with the oil filter, and flashing the throttle at the same time, otherwise the engine will stall, because the throttle of Wuling car has a water cooling device, so it is not recommended to remove and clean it. After washing, remove the air filter to see if it needs to be replaced.

Question 8: The idle speed of the van is unstable, which is what happens after the throttle is cleaned. What's the problem? Buying a semi-automatic idling motor with power-assisted and fuel-saving function online in 25 minutes can solve the problem of idling. This problem is idle system failure.

Question 9: What should I do if the throttle of the van is cleaned or will it automatically refuel? Spend some time with the idle motor ~ I used to drive like the accelerator was stepped on the end ~

Question 10: What should I do if the spark plug of the van burns more carbon? Is it because the accelerator is washed, or is your car burning oil?
