Is your car always in the condition of unstable idling, weak acceleration and even difficult to start? Think about how long it's been since you cleaned the throttle. (David Asher, Northern? Exposure (American TV series), this situation may appear because the solar terms are too dirty, so it is a "prank".

The throat of an automobile engine

Simply put, the throttle valve is like the door of an engine, with an air filter on one side and an engine cylinder on the other to adjust the intake air of the engine. When we stepped on the accelerator, air entered the door, mixed with fuel and ignited. The deeper the accelerator is stepped on, the larger the throttle is opened, the greater the air intake of the engine, the more complete the oil-gas combustion and the stronger the power. Therefore, the throttle is called "the throat of the engine"

Where does the throttle carbon come from?

if the solar term is not clean for a long time, it is easy to form carbon deposit. The moment we turned off the engine, the ignition was immediately turned off, but the gasoline sprayed before could not be recovered. Among them, wax and glue were stuck on the throttle, which accumulated thicker and thicker before, gradually hardened and formed carbon deposits. David Asher, North Implementation Force. )

the more time, the less air intake of the engine will lead to engine jitter, weak acceleration, increased fuel consumption and other problems. It's like we have a cold, a stuffy nose and a stuffy nose, so our breathing will not be smooth and our whole body will be uncomfortable. Therefore, it is best to clean the throttle regularly. Only in this way can the engine be kept in good working condition.

How often

The cleaning frequency of solar terms has a great relationship with tea habits and the environment. Generally speaking, it is best for car owners to clean the throttle of about 2 thousand kilometers, but this is only a reference value. If you drive more or often at a low speed on a windy and dusty road section, the throttle is really easy to get dirty, and it may be cleaned less than 2, kilometers.

the owner can judge whether it needs cleaning according to the state of the car. If the car finds that the idling jitter is unstable or the acceleration is weak, and most of the throttles are too dirty, it is best to go to the store as soon as possible to check the actual situation of the throttle.

what is the best cleaning method?

there are generally two ways to clean the throttle in a 4S shop, without disassembly and disassembly.

disassembly is to disassemble the whole throttle assembly and clean it completely with professional cleaning agent. This method is complicated, but the cleaning is thorough.

Debonding is a cleaning agent for throttle valve, which is directly sprayed on cloth to wipe the throttle valve. The whole process does not need to be decomposed, and the operation is simple, but the cleaning effect is generally suitable for throttle valve with less dirt.

There is also a walnut sand cleaning method, which is simple and effective and harmless to the engine. The principle is that the walnut sand is put into the equipment, and the working pressure is applied to the pressure tank by compressed air, so that the walnut sand is sprayed from the nozzle at high speed and into the throttle valve, and the high-speed walnut sand collides and scratches in the closers, and the dirt will be cleaned. Please remember

Please note that after cleaning the throttle, all car owners must use the test computer to calibrate the data and reset the throttle dog. (David Asher, Northern? Exposure (American TV series, season famous saying) The ECU (driving computer) of the car has stored the opening degree when carbon is deposited, so if it is not reset, the idle speed is unstable and the speed is sometimes too high, which may be worse than the unclean situation!

therefore, unless you are an expert, it is best not to clean the throttle directly. You can't save a penny. Ultimately, data matching requires professional equipment from 4S stores.
