Abstract

The invention provides an intake valve of an internal combustion engine. The intake valve of the internal combustion engine comprises an intake tube (2), wherein the inlet of the intake tube (2) is provided with three valves (7) being the same in the shape and having fan-shaped cross section, and the angle between the engaging surfaces of any two valves (7) and the cross section of the intake tube is 30 to 45 degrees. The intake valve of the internal combustion engine further comprises a valve fixing and driving device, the valve fixing and driving device is fixedly connected with the outer wall of the intake tube (2). The air in the intake tube can be mixed sufficiently, the controllability of the air amount in each air cylinder is good and the combustion efficiency of the engine fuel oil can be guaranteed as well as the engine is protected.

Description

technical field [0001] The invention relates to the field of air intake control equipment for internal combustion engines, in particular to intake valves for internal combustion engines. Background technique [0002] The structure of the intake valve of most automobile engines today is that a linkage mechanism drives an integral disc-shaped throttle valve to achieve the purpose of adjusting the intake air volume of the engine. When the integral disc-shaped throttle valve is perpendicular to the intake pipe, it is fully closed. When the integral disc-shaped throttle valve is parallel to the intake pipe, it reaches the maximum opening and closing state. At any angle, the air flows along the throttle valve and the intake pipe. The gap between the air pipe walls enters. At this time, after the air enters the intake pipe from the gap between the throttle valve and the intake pipe wall, due to the bias flow of the air flow, the distribution of the air flow in the intake pipe is un...
