Disc shaped variable vortex throttle piston for automobile engine, internal combustion engine

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 ...
