How often does Alto clean the throttle?

About the landlord's concern, "How often does Alto clean the throttle?" The following is my personal opinion:

Alto cleans the throttle valve for 20-30 thousand kilometers. Throttle is a controllable valve that controls air to enter the engine. There are two types: traditional cable type and electronic throttle valve. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is called the throat of an automobile engine, which is connected with the air filter and the engine block. The front suspension of Alto adopts McPherson independent suspension, and the rear suspension adopts torsion beam dependent suspension. Equipped with 1.0L naturally aspirated engine, the maximum horsepower is 7 1ps, and the maximum power is 52kw, matching the 5-speed manual transmission.
