How does Li Xia a+ clean the throttle?

First of all, engine cleaning is divided into two parts.

1. Cleaning of fuel system. There are three ways:

A, go to the repair shop for manual disassembly and washing. It can only rush to the nozzle, which has corrosive effect on plastic parts and sealing rings. Cost 100-300 yuan.

B, go to the 4S workshop to clean the equipment. The fuel nozzle and air inlet can be cleaned. Cleaning is fast but not thorough, and a large amount of carbon deposits are easy to fall into the combustion chamber, resulting in three-way catalytic blockage. The cost is 600- 1000 yuan.

C, cleaning with cleaning additives. With fuel as the carrier, oil can be cleaned everywhere, such as nozzle, air inlet, intake valve, combustion chamber, piston ring and so on. However, the cleaning additives on the market all say that they can clean carbon deposits, which is a mixed bag. Cost 200-300 yuan/bottle.
