What is the reason for the increase in fuel consumption after cleaning the throttle?

After the throttle valve is cleaned, the injection diameter of the injector increases, and the amount of fuel injected per unit time increases, resulting in an increase in fuel consumption. The following is a description of cleaning the throttle: Reasons for the increase in fuel consumption: After cleaning the throttle, the increase in fuel consumption is normal. Most cars are like this. The original factory throttle is dirty, especially when the throttle opening is not large. Because the throttle valve is too dirty, the actual diameter becomes smaller and the intake air volume becomes smaller. In order to match the air-fuel ratio, the computer will also reduce the fuel injection. However, after cleaning the throttle valve, the amount of air flowing through the throttle valve suddenly increases, so the precautions for cleaning the throttle valve are: clean the carbon deposit on the electronic throttle valve every 10,000 kilometers, or wait until the fault indicator light is on. After removing the carbon deposit, it will have a certain impact on the performance of the car. After removing the carbon deposit, the driving computer needs a learning process to adapt to the running environment of the automobile engine. The adaptation process is about 1000 km. In general, the computer needs to be reset after cleaning the throttle valve. If you don't do it, it is likely to cause a big increase in fuel consumption. Generally speaking, the simplest reset method is to disconnect the battery cord for more than 30 seconds.
