How often is the throttle maintained? Why does the fuel consumption increase after washing the throttle?

Has your car been in a state of unstable idling, weak acceleration and even difficult starting? Think about how long it's been since you cleaned the accelerator of your car. (David Asher, North? Exposure (American TV series), this situation may be 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 step on the accelerator, air enters the door, mixes with fuel and ignites. The deeper you step on the accelerator, the bigger the accelerator 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 deposit come from?

Long-term unclean solar terms are easy to form carbon deposits. The moment we turned off the engine, the ignition turned off immediately, but the gasoline we sprayed before could not be recovered. Among them, wax and glue stuck to the accelerator, which accumulated thicker and thicker before, gradually hardened and formed carbon deposit. David Ashe, North Executive Force. )

The more time, the less air intake of the engine, which will lead to engine jitter, weak acceleration and increased fuel consumption. It's like we have a cold, and our nose is blocked, so we can't breathe smoothly and feel uncomfortable all over. Therefore, it is best to clean the throttle regularly. Only in this way can the engine maintain a good working condition.

How often do you clean it?

The cleaning frequency of solar terms has a great relationship with tea drinking habits and environment. Generally speaking, it is best for the owner to clean the throttle at about 20 thousand kilometers, but this is only a reference value. If you drive more on windy and dusty roads or often drive at low speed, the throttle is really easy to get dirty, and it may be cleaned in less than 20 thousand kilometers.

The owner can judge whether it needs cleaning according to the state of the car. If the car finds that the idle speed is unstable or the acceleration is weak, and most of the throttle is 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 most suitable cleaning method?

There are generally two ways to clean the throttle valve in 4S shop, no disassembly and disassembly.

Disassembly is to disassemble the whole throttle assembly and thoroughly clean it 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 the cloth to wipe the throttle valve. The whole process does not need decomposition, and the operation is simple, but the cleaning effect is generally suitable for throttle valves 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 compressed air is used to apply working pressure to the pressure tank, so that the walnut sand is ejected from the nozzle at high speed and enters the throttle valve, and the high-speed walnut sand collides and scratches in the closer, 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, North? Exposure (American TV series, season famous sayings) The ECU (driving computer) of the car has stored the opening when carbon is deposited, so if it is not reset, the idle speed is unstable, and sometimes the speed is 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. Not a penny can be saved. Finally, data matching requires professional equipment from 4S stores.
