What is the normal throttle opening? Does the throttle opening need to be repaired?

Throttle is a switch to control the air inlet, where air enters and then mixes with fuel to form combustible gas. The throttle valve has a valve. When it is open, air will enter from here, and when it is closed, the valve will be completely closed. The throttle can't be opened too much, which will have some influence, so how much is the throttle generally opened? Does the opening need mending?

What is the throttle opening? Normal throttle opening is the opening of engine throttle. The driver can change its angle through the accelerator pedal. When the car is idling, the normal throttle opening is generally around 3-5%, and it is generally not more than 8% at the beginning, but it also varies with different models. If the opening value is a bit large, it is generally not that the throttle is broken, and it is estimated that the throttle is too dirty. Just wipe the throttle clean.

For the electronic throttle, accurately speaking, if there is no bypass idle channel, the idle speed of the car is maintained by opening the electronic throttle to a certain extent. Some models have electronic throttle body, and some idle motors with bypass pipes are turned on at a certain angle to control idle speed.

Does the throttle opening need to be repaired? This is generally caused by carbon deposition, so it is recommended to clean it.

The throttle opening standard of different models is different, and the throttle also depends on whether it is electronic or mechanical. Whether the throttle valve has a bypass valve.

If the idle speed becomes low or unstable. Electronic throttle generally has no bypass valve. At this time, if you don't step on the accelerator, the idle speed will normally start at 5%, and it will not exceed 8% when starting. If it exceeds a lot, the intake pipe and throttle need to be cleaned. If the throttle valve is opened too much, it will lead to unstable idle speed of the engine, abnormal black smoke from the exhaust pipe and corresponding increase in fuel consumption.

If the throttle has a bypass valve, the engine has a fault light. At this point, it means that there is too much carbon deposit, and the bypass valve may be blocked.

If there is no bypass valve of mechanical throttle, the opening of 17% is not too big, just a little bigger. There is nothing serious at this time, but there is a slight carbon deposit on the accelerator, which can be cleaned or ignored.

What does the throttle opening mean? The throttle valve controls the intake of the engine through the valve plate in the middle of the air passage, and completely closes the air passage when the engine is turned off. When the engine is idling, ECU will control the throttle plate to rotate by a small angle according to the idling speed to ensure the air intake of the engine. Because the air intake at idle speed is very small, the throttle will rotate by 2%-5%, which is the throttle opening.

A few days ago, it was learned from the official of Wuling Automobile that Wuling has added a number of operating models, including five versions of Wuling Hong Guang V, Wuling Hong Guang PLUS and Wuling 730, and the price is 545-73800. Most of these models are low-profile versions of autonomous models, but more safety configurations such as front double airbags, central locking and tire pressure monitoring have been added. Mainly suitable for some consumers with short-distance passenger transport needs. The operating version of Wuling 730 was transformed from Baojun 730. The appearance of the new car basically follows the main design of the old Baojun 730, only replacing the Wuling brand's China Net and the whole car logo.
