Abstract: An improved throttle body structure is provided. The structure includes a throttle body. The throttle body is provided with a plurality of airflow channels running from top to bottom, each of the airflow channels is internally provided with a butterfly valve for controlling a ventilation volume, and the throttle body is internally provided with injectors whose quantity corresponds to a quantity of the airflow channels. Each of the airflow channels is further internally provided with a tubular atomizer mounted and fixed in a radial direction, the atomizer is in a shape of a blind tube with one opening end, a tube wall of the atomizer is provided with a plurality of atomizing holes, and the opening end of the atomizer is connected to the injectors. The tubular atomizer is used, and the opening end of the atomizer is directly connected to the injectors.

Abstract: An electronic throttle body with an improved structure includes a throttle body. A plurality of vertically through airflow channels are provided on the throttle body, and a butterfly valve controlling a vent flow and a fuel atomizing ring configured to atomize fuel are arranged in each airflow channel. Centers of one or more butterfly valves are connected in series through rotating shafts to implement linked flipping, the rotating shafts are arranged parallel to each other, a drive gear is fixedly mounted to one end of each rotating shaft extending out of the throttle body coaxially, and the rotating shafts rotate synchronously through a servo driving apparatus. The servo driving apparatus and electrically controlled sprays respond synchronously, thereby improving the combustion efficiency of fuel in an engine. When the engine is idle, butterfly valves are directly driven through the servo driving apparatus to accurately control an air inflow of the engine.
