Problems solved by technology

[0002] For nearly a hundred years, the throttle valve of automobiles has such a structure: as shown in Figure 1, an integral disc throttle valve is designed in the intake pipe, which is driven by a connecting rod mechanism, and the integral disc throttle valve is connected with the intake pipe. When it is vertical, it is closed. When there is any angle, the throttle valve is opened, and the air enters along the gap between the valve and the wall of the intake pipe. At this time, such a situation will be formed: the air flowing into the lower side of the throttle valve is fast, The air flowing into the upward side of the valve is slow, the air intake is uneven, and a certain vacuum will be formed at the position of the valve shaft at the moment of opening, so that when the valve is opened, the air flow rate is slow, the resistance is large, and the fuel is not completely burned. air pollution

Embodiment

[0014] The disc-shaped automobile engine described in this embodiment, the variable vortex throttle valve of internal combustion engine, its disc has an outer ring gear 2, and this outer ring gear 2 is connected with intake pipe 1, and the disc is evenly divided into three For the same fan-shaped throttle valve 3, guide vanes 4 are designed on the downwardly rotating side of each throttle door, and the guide vanes are perpendicular to the throttle valve. Each fan-shaped throttle valve 3 is fixed on the throttle valve shaft 5, and the outer ring gear On ring 2, there is a throttle shaft gear 8 at the position corresponding to the throttle shaft. The throttle shaft 5 is fixedly connected to the throttle shaft gear 8, and one of the throttle shaft gears is fixedly connected to the throttle drive disc 7. The outer ring The ring gear 2 meshes with the throttle shaft gear 8. When the throttle valve needs to be opened, the throttle driving disc 7 drives the outer ring gear 2 to move ...

Abstract

The invention relates to a disk shaped variable eddy current restrictor of automobile engine and internal combustion engine. The disk is divided into more than three same sectorial restrictor 3, each sectorial restrictor 3 is fixed on the restrictor shaft 5, and rotate driven by restrictor driving disk 7. When the restrictors are opened simultaneously, under the action of engine negative pressure, airflow will flow in along the incline with flow guiding leaf of each restrictor, and generate eddy, and increase the intake airflow and intake pressure, for making oil combust completely, and improving the engine torsional moment and the throttle sensitivity in slow or medium speed. The invention can shorten the air intake pipe of existing engine for decreasing the intake resistance of engine working under the maximum load.

Description

technical field [0001] The invention relates to the improvement of throttle valves of gasoline and diesel automobile engines and internal combustion engines. technical background [0002] For nearly a hundred years, the throttle valve of automobiles has such a structure: as shown in Figure 1, an integral disc throttle valve is designed in the intake pipe, which is driven by a connecting rod mechanism, and the integral disc throttle valve is connected with the intake pipe. When it is vertical, it is closed. When there is any angle, the throttle valve is opened, and the air enters along the gap between the valve and the wall of the intake pipe. At this time, such a situation will be formed: the air flowing into the lower side of the throttle valve is fast, The air flowing into the upward side of the valve is slow, the air intake is uneven, and a certain vacuum will be formed at the position of the valve shaft at the moment of opening, so that when the valve is opened, the air ...
