How often does Rena clean the throttle?

Everyone is concerned about "how often does Rena's throttle clean?" Let me explain something to you:

Rena's throttle is cleaned every 20,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. 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. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. The length, width and height of Rena are 4300mm, 1705mm and 1460mm respectively, and the wheelbase is 2570mm. Equipped with 1.4l naturally aspirated engine, the maximum power is 70kw, and the maximum torque is 132.4nm, matching with a five-speed manual gearbox.
