Throttle is mainly composed of valve and throttle valve.

These are two pipes-the pipes are for heating the throttle body! Due to the cold climate in the north. The air flow in the damper is large, and it is easy to freeze in winter! In order to avoid this situation, it is a small cycle to heat the throttle body of the cylinder head by pumping it out of hot water. The water temperature is kept at about 90 degrees. It should be noted that there are two clarinets in front of the throttle body, namely the positive crankcase ventilation system (PCV).
