Embodiment Construction

[0020] In view of the defects in the prior art, in order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0021] as attached Figure 5 , 6 , 7, the energy-saving throttle disclosed in this embodiment is used as a control component to control the intake air volume of the engine, so that the intake air volume, flow rate, and pressure are more uniform, and it can increase the air intake rate in the unit air intake section compared with the existing structure throttle valve. Pressure, to provide more sufficient combustion air for the internal combustion engine, so that the fuel is more fully fueled.

[0022] The energy-saving throttle valve designed in this embodiment includes a housing 1 provided with an air intake passage 11 and an air flow control valve plate 4 installed in the air intake passage 11 through a rotating shaft 3, wherein the valve plate 4 m...

Abstract

The invention relates to an energy-saving throttle, comprising a shell provided with an air inlet channel and an airflow control valve disc arranged in air inlet channel through a rotating shaft; the valve disc consists of a first valve disc and a second valve disc which are symmetrically arranged and swing in opposite directions along the rotating shaft; the two valve discs are provided with arc grooves which transform airflow passing through the valve discs into cyclostrophic flow. In the invention, airflow passing through the air inlet channel of the throttle is transformed into cyclostrophic flow and enters cylinders, so that airflow which enters all the cylinders becomes more uniform and stable and has faster flow velocity; as a result, fuel oil in a combustion motor can burn more fully, output power is improved and exhaust emission is accordingly reduced under the condition of the same amount of fuel oil, thus achieving the purpose of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to an improved structure of a throttle valve. Background technique [0002] as attached Figure 1~4 Shown is a schematic diagram of the existing common engine throttle structure. This type of engine throttle is mainly controlled by a housing 1 provided with an intake passage 11 and a circular valve piece 2 to control the intake air. The intake passage is a circular hole, and the circular valve piece is a whole circle. It is connected with the rotating shaft 3 in the casing, and the circular valve plate is driven to rotate through the rotating shaft to adjust the opening size of the intake passage. When the circular valve piece rotates an angle to open the intake passage, part of the gas (see attached figure 2 Part of the airflow in the direction of middle A) due to the obstruction of the circular valve plate, the flow to the inner wall of the intake passage impacts to the inner wall and then bends to flow to the engine, part of...
