6.2.16 Air Filter
The engine is a very precise machine part, and even the smallest
impurities will cause the wear of the engine. Therefore, the air must be filtered
by the air cleaner before entering the cylinder. Therefore, the disassembly,
maintenance or replacement of the air filter will cause some particulate
impurities in the air to enter the car parts. At this time, the air filter learning and
matching functions need to be performed to make the air filter work normally.
