Abstract
The utility model provides a throttle valve and an idle speed control device for an engine. The throttle valve comprises a valve body and a valve block which is arranged inside an chamber of the valve body; the valve block which is flexibly arranged inside the chamber of the valve body can swing around a throttle valve shaft; the throttle valve shaft is connected with the valve body; the internal wall surface of the chamber is a curved surface; a gap which is used for enabling the air leakage amount to be increased and decreased smoothly is formed between the periphery of the valve block and the internal wall surface of the valve block. The throttle valve has the advantage of accurately control the air inlet amount of the engine under the idle speed state.
Description
Technical field
The utility model relates to a kind of throttling arrangement, particularly the throttle valve of air inflow and the idle speed controller of motor under a kind of accurately control engine idling mode.
Background technique
The idling operation of motor is even more important concerning the vehicle travelling on urban road, and dead time accounts for 1/3 of total run time, and fuel consumption accounts for 30% of cumulative fuel consumption.In vehicle behavior emission test, the amount of substance such as the carbon monoxide of idle exhaust emission account for 70% left and right of total displacement conventionally.The height of auto idle speed rotating speed is the key factor that affects engine fuel consumption and control discharge, past attempts thinks that idling is more low better, like this can capable of saving fuel oil, but idling is lower, more easily cause the unstable combustion of motor even flame-out, so denseer mixed gas is provided, this can make again the discharge of the materials such as carbon monoxide increase.The target of Gasoline Engine on Idle control should reduce under the discharge amount of the materials such as carbon monoxide as much as possible, keeps idling operation to operate steadily under lower rotating speed, to reach the object of saving fuel oil and reducing discharge; Reaching the above object will be more accurate to rotating speed control, and the air quantity of entering while relating to idling is accurately controlled.
The control of motor to air inflow, the namely control to electronic throttle valve opening.Under idling operation, throttle valve body aperture mainly concentrates on valve block and opens and control to the angle limping position from full close position.When idling, air leakage rate is exactly the air quantity that air flows through from the gap producing between valve block and body.
Model utility content
The technical problems to be solved in the utility model is that the electronic throttle in order to overcome prior art enters the coarse defect of air quantity under idling operation, and the throttle valve of air inflow and the idle speed controller of motor under a kind of accurately control engine idling mode is provided.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of throttle valve, it comprises that a valve body and is arranged at the valve block in the cavity of this valve body, this valve block is movably arranged in the cavity of this valve body and can swings around this throttle plate pin by a throttle plate pin, this throttle plate pin is connected with this valve body, the internal face of described cavity is a curved-surface structure, between the periphery of described valve block and this internal face, is formed with the gap that can make air leakage amount increase gently or subtract in the time that valve block swings.
Preferably, this curved surface is the blending surface that includes any two or three in concave surface, convex surface and plane, and between each concave surface, convex surface and plane for being smoothly connected.
Preferably, one end of this throttle plate pin and this valve body are affixed, and the other end and this valve block are affixed.
Preferably, this throttle valve is an electronic throttle, this electronic throttle also comprises that one for controlling the electronic control unit of this valve block amplitude of fluctuation, this electronic control unit is connected to by wire harness on the socket of this electronic throttle, and transmit the control signal between this electronic throttle and this electronic control unit by wire harness, this electronic control unit is for sending the instruction that drives direct current generator, this direct current generator drives joint reseting gear to rotate by intermediate gear, and this throttle plate pin is fixed on this joint reseting gear.In the time that this joint reseting gear rotates, this throttle plate pin is followed rotation like this, and now this valve block is opened or closes with this throttle plate pin.
Preferably, the upper end of this valve body has a suction port, and the lower end of this valve body has an air outlet.The air entering from suction port can flow through the gap between valve block and valve body, and discharges from air outlet.
An idle speed controller for motor, it comprises throttle valve as above.
Positive progressive effect of the present utility model is: be convenient to control the engine air capacity under idling mode.

Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment 1
Understood incorporated by reference to Fig. 2, Fig. 3, a kind of throttle valve comprises that a valve body 1 and is arranged at the valve block 3 in the cavity 2 of this valve body 1.This valve block 3 is movably arranged in the cavity 2 of this valve body 1 and can swings around this throttle plate pin 4 by a throttle plate pin 4, one end of throttle plate pin 4 and this valve body 1 are affixed, the other end and this valve block 3 affixed (such as, valve block 3 passes throttle plate pin 4 and is fixed on throttle plate pin 4), curved surface and the valve block 3 of the internal face 5 of cavity 2 match around the rotary motion trace of throttle plate pin 4, and then make the leakage rate variation of motor required air in the time of idling milder, be convenient to the idle speed control of motor.The internal face 5 of cavity 2 is a curved-surface structure, and this curved surface is the blending surface that includes any two or three in concave surface, convex surface and plane, and between each concave surface, convex surface and plane for being smoothly connected.Between the periphery of valve block 3 and this internal face 5, be formed with the gap 6 for air leakage amount can be increased and decreased gently.This throttle valve is an electronic throttle, this electronic throttle also comprises that one for controlling the electronic control unit of this valve block amplitude of fluctuation, this electronic control unit is connected to by wire harness on the socket of this electronic throttle, and transmit the control signal between this electronic throttle and this electronic control unit by wire harness, this electronic control unit is for sending the instruction that drives direct current generator, this direct current generator drives joint reseting gear to rotate by intermediate gear, this throttle plate pin is fixed on this joint reseting gear, in the time that this joint reseting gear rotates, this throttle plate pin is followed rotation, now this valve block is opened or closes with this throttle plate pin.The upper end of valve body 1 has a suction port, and the lower end of this valve body 1 has an air outlet.
