Abstract
A variable air inlet pipe for an engine comprises an air inlet interface, an air outlet interface, a casing, a closing plate, a rotary slide block, a stepping motor and a control system; the casing is annular, and the rotary slide block has an annular outer surface and is connected with the stepping motor; the annular outer surface of the rotary slide block is in sliding fit with the closing plate; the two side surfaces of the rotary slide block are in sliding fit with the inside wall of the casing; a pipeline is formed by the rotary slide block and the casing; the closing plate is positioned on one side of the air outlet interface and closes the pipeline formed by the rotary slide block and the casing; and the air inlet interface is formed in the center of the casing. The variable air inlet pipe has the advantages that the length of an air inlet pipe can be adjusted accurately and continuously, and the structure is simple.
Description
Technical field
The utility model relates to a kind of engine variable suction tude.
Background technique
For good utilisation resonant intake system effect more improves air input of engine by air, the suction tude of more existing variable-lengths is used for motor car engine, when high engine speeds with short suction tude air feed, during low speed with progress tracheae air feed.They are divided into length has level can be in harmonious proportion adjustable two classes of stepless continuous.Length has the adjustable suction tude of level to utilize the resonant intake system effect to improve air input of engine by air under some rotating speeds of motor.The suction tude that the length stepless continuous is adjustable then can be accomplished under each rotating speed of motor.Patent 201120177953.7 discloses the adjustable suction tude of a kind of length stepless continuous, but its needs to rotatablely move and be converted to straight line motion by leading screw and nut, and structure is comparatively complicated.
Summary of the invention
For the deficiency that solves the problems of the technologies described above, the utility model provides a kind of length stepless continuous adjustable suction tude, need not to be converted to straight line motion with rotatablely moving, and can make motor can both utilize the air inlet resonance effect to improve air inflow under each rotating speed.
The technological scheme that its technical problem that solves the utility model adopts is: designed variable inlet duct comprises intake interface, the interface of giving vent to anger, housing, shut, turning block, component such as stepper motor and control system, described housing is circular, turning block has rounded outer surface, turning block connects with stepper motor, the rounded outer surface of turning block and shut sliding fit, turning block bi-side and housing madial wall sliding fit, turning block and housing form pipeline, shut is positioned at a side of the interface of giving vent to anger and seals turning block and the formed pipeline of housing herein, and intake interface is positioned at the housing center portion.
The working principle of the technical program is, control system is according to parameters such as engine speed, and to the instruction that stepper motor sends amounts of rotation, therefore drive turning block rotates corresponding angle to stepper motor, thereby change the length of turning block and pipeline that housing forms, also just changed intake manifold length.
The beneficial effects of the utility model are, can regulate intake manifold length accurately, continuously, make motor can both utilize the air inlet resonance effect to improve air inflow under each rotating speed, and are simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's main insight structural map.
Fig. 2 is the A-A sectional view of Fig. 1.
1. give vent to anger interface, 2. housing, 3. turning block, 4. intake interface, 5. stepper motor, 6. shuts among the figure.
Embodiment
Among the embodiment by Figure 1 and Figure 2, variable inlet duct comprises intake interface (4), the interface (1) of giving vent to anger, housing (2), shut (6), turning block (3), stepper motor (5) and control system component such as (not drawing among the figure), housing (2) is circular, turning block (3) has rounded outer surface, turning block (3) connects with stepper motor (5), the rounded outer surface of turning block (3) and shut (6) sliding fit, turning block (3) bi-side and housing (2) madial wall sliding fit, turning block (3) forms pipeline with housing (2), shut (6) is positioned at a side of the interface of giving vent to anger (1) and seals turning block (3) and the formed pipeline of housing (2) herein, and intake interface (4) is positioned at housing (2) center portion.During work, control system is sent rotation command according to parameters such as engine speed to stepper motor (5), and therefore drive turning block (3) rotates corresponding angle to stepper motor (5), thereby change the length of turning block (3) and housing (2) institute formation pipeline, also just changed intake manifold length.
Because control system is sent the pulse signal of accurate control step motor (5) according to parameters such as engine speed, the rotation angle of turning block (3) is just precisely controlled by stepper motor (5), turning block (3) is also just accurately controlled with the length of housing (2) institute formation pipeline, continuously change intake manifold length thereby reach according to engine operating condition, realize that motor can both utilize the air inlet resonance effect to improve the purpose of air inflow under each rotating speed.
Claims (1)
1. engine variable suction tude, comprise intake interface, the interface of giving vent to anger, housing, shut, turning block, component such as stepper motor and control system, it is characterized in that: housing is for circular, turning block has rounded outer surface, turning block connects with stepper motor, the rounded outer surface of turning block and shut sliding fit, turning block bi-side and housing madial wall sliding fit, turning block and housing form pipeline, shut is positioned at a side of the interface of giving vent to anger and seals turning block and the formed pipeline of housing herein, and intake interface is positioned at the housing center portion.
