How is the high fuel consumption after cleaning the throttle?

1, after washing, the injection diameter of the 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 the throttle valve is cleaned, the clearance is larger.

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

Extended data:

There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.

Maintenance of throttle valve:

1, which should be dismantled and cleaned;

2. Correct some mistakes in cleaning the throttle valve;

3. The fouling of the throttle is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle will be much slower.

The crankshaft is built in the crankcase, and the lower part is connected with the oil bottom. The working temperature of this part is about 100 ~ 180.
