After washing the accelerator, the fuel consumption of Animal 650 becomes higher.

1. After cleaning, the fuel injection diameter of the fuel injector increases, and the fuel ejected per unit time increases, so the fuel consumption increases.

2. Because the throttle valve was cleaned and the relevant matching treatment was not done, the computer detection program still adjusted the fuel injection amount according to the original throttle valve calculation. Generally speaking, cars will gradually adapt to this possibility after driving for a period of time.

3. The position of throttle and throttle arm is worn too much, because the throttle has not been cleaned for a long time. At this time, after cleaning the throttle, the gap is even bigger.

4. Too much carbon deposition in the throttle will lead to irregular throttle closing, which will lead to increased fuel consumption.
