Cleaning the throttle can reduce fuel consumption?

Cleaning the throttle can reduce fuel consumption?

If the throttle is dirty, cleaning does have an effect.

First of all, the throttle is really dirty, which is really a little different from the carbon deposit in our usual impression.

The oil will condense on the air intake and throttle, and then the carbon deposited in the steam will also deposit on these parts. These dirty things on the accelerator are more like a layer of oil pollution than a simple layer of carbon deposit. Imagine a dirty range hood.

If the throttle has a thick oil stain, the air intake at the same opening will actually decrease.

How long does it take to clean the throttle?

So how soon will the throttle get dirty and need cleaning?

Different models are actually different. Some cars get dirty faster, but some cars are 70,000-80,000 km, which seems to have no feeling.

Except for this special model, most cars can wait until they feel unusually obvious before washing.

How is it that the fuel consumption of cleaning the throttle valve becomes higher instead?

After the throttle valve is cleaned, the ECU still controls the air-fuel ratio of the mixture according to the original learning adaptation value. As a result, it is divorced from the actual needs, which often leads to abnormal engine idle speed and increased fuel consumption.

ECU didn't know we washed it, and thought it was dirty. According to the original habit, is it still panting? If you don't change it, there will be some adverse reactions.

It is not entirely accurate to say that washing the throttle can reduce fuel consumption.

So in general, 4S stores say that washing the throttle can reduce fuel consumption, which is not completely rigorous or accurate.

Only when the throttle is really dirty and exceeds the original adjustment range will it be cleaned and re-matched, and the fuel consumption will be improved.
