Solar term door is one of the most important parts of the modern system of EFI engine, the owner is usually the most discussed focus. Whether you go to the 4S shop or repair shop, there will always be some people to you recommend cleaning solar term door, little take many spent hundreds, so not too understand the difficult choices, below Cairo electronic throttle for everyone to introduce throttle related knowledge.

What is the throttle valve

Throttle control air into the engine of a controllable valve, when air enters the intake pipe and gasoline mixed become combustible gas mixture, involved in the combustion of acting. The upper part of the air filter is the air cleaner, the lower part of the engine block, and the throat of the engine.. Whether the vehicle acceleration is flexible and idle is stable, and the cleanliness of the throttle valve has a certain relationship.

Two, throttle type

Solar term door pull door is divided into solar term and electronic solar term door two. Carol electronic throttle says traditional engine throttle control mechanism is through cable throttle cable) or pull rod, and the other end is connected to the gas pedal, and the other end is connected with throttle linkage plate and work. The electronic throttle valve is mainly through the throttle position sensor to control the opening angle of the throttle valve according to the engine energy, thus adjusting the intake quantity. The pull type throttle has gradually been eliminated, more advanced, more and more electronic throttle.

Three, clean throttle cycle

How long will the throttle valve depends on the air filter quality, the quality of the oil, the road, air temperature, engine operating temperature, driving habits and so on many aspects. Even if the individual is not able to determine the time for cleaning the throttle fixed number of kilometers. Car the first cleaning solar term door the longest interval, due to the crankcase ventilation tube and the inlet port of oil and gas continue to condensation, cleaning frequency will increase and the different weather will impact throttle dirty speed. So by several kilometers to determine intervals of throttle cleaning is not accurate, general when driving appear idle instability, traveling by car, acceleration, or oil collecting cars suck and flameout phenomenon, consider whether or not the throttle dirty.

Four, throttle cleaning method

The specific cleaning method of the throttle valve can refer to another article of the vehicle maintenance "how to clean the throttle valve". By the way despise part of the repair shop or 4S shop use do not dismantle the section valve in place scrub practice, after the owners of friends met this can not go to this shop again.

Five, how to prevent premature valve premature change dirty

1 try to reduce the time when the idling car.

2000 use of manual file models to avoid high-grade low-speed driving, should be 2 to shift the above.

3 less congested road, running high-speed.

4 air filter to frequently change, and do not use the filter filter.

5 to use suitable oil.

Six, clean the throttle why the initial initialization

Cairo said electronic throttle for electronic throttle, throttle cleaning after the initialization is a must. Because the computer adjusts the throttle open degree when is has the memory function, because the previous sludge blockage, in order to ensure the air intake, the computer will automatically adjust the throttle opening, so that the air intake in the normal state. And after cleaning, no sludge blockage. If throttle also maintained before the opening, then it will cause excessive intake. If the throttle valve is not initialized after cleaning, the electronic unit and idle speed control element will appear the work of the non coordination, performance is idle speed control is not accurate, unstable, such as idle and high and high. However, this kind of bad performance is only temporary, because the electronic control unit has the function of studying and adapting automatically, but this study is not as fast as the adaptation process.. Some models clean the throttle after the throttle, not only to initialize, but also to remove the original learning value. This is related to computer software for models.

Seven. Manually initialized throttle valve method

Cairo electronic throttle said initialization method according to the different cars there are mainly two kinds of:

1 key second gear, also is the instrument indicating the full light of that file, and then wait for 20 seconds, the pedal to the metal, maintain 10 seconds, release the accelerator pedal, switch off the ignition, remove the key and initialization is complete.

2 open key second stop, hold for 30 seconds, then turn off ignition switch, pull out key.

Carol electronic throttle remind the need to pay attention to is that finish after two kinds of methods, to wait for a period of time, can try to strike, waiting for 15 - 20 seconds, and then strike a light, look at idle is normal, if at first you don't succeed, do it the second time, until the success so far. But according to the models of different reduction method is not the same, some cars must to through the computer to complete the initialization if it is that it is recommended that the owner of the car sent to have professional equipment store to do the cleaning.
