Abstract

The invention relates to a hinge type throat adjusting system and belongs to the technical field of internal combustion engines. The hinge type throat adjusting system comprises an engine air inlet pipe, an engine, an engine exhaust pipe, a vane plate, a rotary shaft, a push-pull rod, a moving body, a spring, a slide body and a connecting pipe, wherein the vane plate is arranged in an air inlet branch and fixedly connected with the rotary shaft, the right wall face of the slide body is connected with right wall face of a control body through a second spring, one end of the connecting pipe is communicated with the inner cavity of the control body, the other end of the connecting pipe is connected with the engine exhaust pipe between a catalyst package and a silencer. The hinge type throat adjusting system has the advantages that air inlet tumble is large when the engine operates under a low-speed working condition, and pump air loss is small when the engine operates under a high-speed working condition; the hinge type throat adjusting system is reasonable in design, simple in structure and applicable to optimization design of the air inlet system of natural air suction internal combustion engines.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a articulated neck adjustment system capable of realizing self-regulation of an air intake system of a naturally aspirated engine. Background technique [0002] At the beginning of the 20th century, British B. Hopkinson found in the internal combustion engine test that when the air in the cylinder is disturbed, the combustion process can be accelerated Effect, the use of tumble flow to increase the turbulence intensity in the combustion chamber and the use of lean mixture combustion mode, etc., have become the focus of research on spark ignition engines. The air movement in the engine cylinder is transient and complex. From the point of view of the overall movement of the gas macroscopically, it generally appears as an oblique axis vortex. At this time, the vortex and tumble can be regarded as two independent components of the oblique axis vortex....
