Why is the fuel consumption getting higher and higher after cleaning the throttle?

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

It is best to clean up the carbon deposit in the intake pipe and the carbon deposit in the valve, and use the computer to match and learn after the oil circuit is washed, otherwise the data read by the computer will still be the data before you wash it, and at this time you have washed it, but the computer parameters are still the same, so the fuel injection quantity will increase and the fuel consumption will increase.

Extended data

1. The time for minor maintenance depends on the effective time or mileage of the old oil and oil filter. Different brands of mineral engine oil, semi-synthetic engine oil and whole synthetic engine oil have different validity periods, please refer to the manufacturer's recommendation. Oil filters are generally divided into conventional oil filters and long-acting oil filters. The conventional oil filter is replaced by oil, and the long-acting oil filter has a longer service life.

2. Engine oil is the lubricating oil for engine operation. It can play the role of lubrication, cleaning, cooling, sealing and reducing engine wear. It is of great significance to reduce the wear of engine parts and prolong the service life.

3. The oil filter is a component used to filter oil. Engine oil contains a certain amount of colloid, impurities, moisture and additives; In the process of engine operation, metal chips, impurities in the inhaled air, oil oxides, etc. generated by the friction of various components. Are the targets of oil filter. If the oil directly enters the oil circuit without filtering, it will have an adverse impact on the performance and life of the engine.
