Description
Technical field
the utility model belongs to technical field of internal combustion engines, is specifically related to a kind of plug-type engine charge control gear.
Background technique
20 beginnings of the century, Britain B.Hopkinson finds in engine test: during air in disturbance cylinder, can accelerated combustion process.After the eighties, the air movement in cylinder is organized by the gas handling system of motor, eddy current is utilized to realize charge stratification firing effect, stream is rolled in utilization to be increased the turbulence intensity in firing chamber and adopts lean combustion pattern etc., all becomes the research contents that current spark ignition engine is paid close attention to.Air movement in cylinder is transition and complexity, from the mass motion of gas macroscopic view, generally shows as inclined-axis swirl.At this moment eddy current and roll stream can as inclined-axis swirl two independently component.Test finds that rolling stream can improve the turbulence intensity compressing air movement at the end firing chamber equally, increasing turbulence intensity can impel rate of flame propagation to accelerate, and combustion duration shortens, and rate of heat release improves, thus improve combustion process, improve the power character of motor.Roll stream mode and be better than eddy current, because the formation of rolling stream relies on casing wall and piston movement, larger kinetic energy can be preserved in intake process, in compression process, a part of kinetic energy makes the air movement of large scale be broken into the microvovtex of numerous small scale, improve the turbulence intensity in cylinder, and eddy current generally experiencings the process of constantly decay.As a whole, why stream is rolled in petrol engine employing is because petrol engine rotational speed is higher on the one hand, this just causes each combustion stroke needs to complete within the shorter time, and rolls the tubulence energy that stream can ensure that the phase is larger upon compression, makes rate of flame propagation increase not shorten combustion duration; Two is the restrictions due to structure, and the available space of petrol engine is less, and swirl air passage takes up room larger.
Through existing literature search, find that number of patent application is 20121041673.5, name is called that a kind of petrol engine variable air inlet rolls the patented technology of stream controlling mechanism, provide a kind of electric actuator that utilizes to the technology regulating air inlet to roll stream, but he can not realize the self-control that stream is rolled in air inlet.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can realizes the plug-type engine charge control gear that the self-control of stream is rolled in air inlet.
The technological scheme that the utility model adopts is:
A kind of plug-type engine charge control gear, comprise connect successively engine air inlet tube, intake manifold, air intake branch, motor and engine exhaust pipe, engine air inlet tube is provided with air filter, closure, engine exhaust pipe is provided with catalysis bag, baffler, it is characterized in that:
In air intake branch upper wall surface be provided with perpendicular to air intake branch pipe to running shaft, running shaft is fixed with guide-leaf plate, guide-leaf plate plate face perpendicular to air intake branch pipe to.
Air intake branch pipe is outside equipped with the control volume of chamber shape, and control volume inside is provided with shifting board, is provided with spring between shifting board end face and control volume inner top surface, and shifting board plate edge seals with control volume interior sidewall surface and contacts;
Guide-leaf plate movable end end is connected with the pull bar stretching out air intake branch by articulated manner, pull bar the other end end is stretched into control volume from bottom and is connected to shifting board by articulated manner;
Cavity in control volume below shifting board is provided with connecting tube, the engine exhaust pipe between access motor and catalysis bag.
The utility model has the following advantages:
The utility model is reasonable in design, structure is simple, can realize natural aspiration, engine aspirating system self-control, when motor air inlet Tumble and swirl when speed operation runs is larger, when high-speed working condition runs, pumping loss is less, is applicable to the optimal design of natural aspiration induction system of internal combustion engine.
