Description
Technical field
The invention relates to a kind of throttle control structure of engine, the overall volume of throttle valve maximizes by espespecially a kind of avoiding, simultaneously can the allocation project of summary engine intake, and then can promote the throttle-valve structure of engine of use effect of engine.
Background technique
Cooperatively interacting between the design of air inlet pipeline and engine is very important for engine, such as, engine at a slow speed or claim the slow-speed of revolution time, the sectional area of the air inlet pipeline required for it is less, length is longer, so can be conducive to improving the gas flow rate in air inlet pipeline, and therefore strengthen effect of inertia and pulsation effect, and then promote intake efficiency, increase engine torque; Otherwise engine is in fast or when claiming high rotating speed, the air inlet pipeline sectional area needed for it is comparatively large, length is shorter, so can reduce flow resistance, thus be conducive to the lifting of intake efficiency, and then improve combustion process, promotes horsepower.
Refer to shown in Fig. 1, the function mode of engine 1, control appropriate fuel oil by electronic control unit (ECU) 11 via injection apparatus 12 to spray in the firing chamber 13 of engine 1, this fuel oil is mixed into mist of oil shape with the extraneous fresh air entered by throttle valve (variable air inlet component) 2, and send Ignition signal to spark coil 14 by electronic control unit 11, make ignition mechanism (spark plug) 15 fight this mist of oil lighted, make piston 16 reciprocating by this, 16, this piston band dynamic crankshaft 17 rotates, and produces power by this.
But, when vehicle non-under travelling state time, 1, engine is that (idling) at low speed mode operates, and avoids engine 1 to stop working by this.This engine 1 is when idling operates, electronic control unit 11 can reduce the amount of fuel sprayed via injection apparatus 12, extraneous fresh air simultaneously, then supplied by the idle speed air admission bypass 21 being located at variable air inlet component 2 other, this idle speed air admission bypass 21 is provided with electronic control valve 211, the extraneous fresh air inlet of control by this electronic control valve 211, makes the idling running that engine 1 can remain fixing by this.
Known engine 1 by be set forth in that throttle valve 2 is other arranges idle speed air admission bypass 21 and electronic control valve 211, no doubt can make the idling running that engine 1 can remain fixing, not stop working and the object of minimizing fuel consume to reach engine 1.As shown in Figure 2, when engine 1 links a generator 3 or other power in addition, this generator 3 linked in addition just can be activated when being and operating in engine 1 in idling, now meeting undoubtedly causes the load of engine 1 significantly to increase, this engine 1 is generator 3 normal operation that this can be allowed external, rotating speed that engine 1 certainly will will promote its running come in response to.The above-mentioned idle speed air admission mode of the engine 1 commonly used obviously cannot be in response to, and engine 1 load transients when idling operates increases, and must promote the demand that air inflow improves to make engine 1 rotating speed simultaneously.Therefore how to provide a kind of engine 1 that makes can because of the control structure of the throttle valve 2 of non-loaded idling and load idle speed air admission amount, the real problem urgently overcome for current Rail car manufacture dealer.
Summary of the invention
Because known throttle valve cannot provide the non-loaded idling of engine and the disappearance of load idle speed air admission amount simultaneously.
Technical way of the present invention is in the throttle control structure providing a kind of engine, and this throttle valve at least includes valve body, valve, control block, control unit, control motor and controls flap; This valve is provided in valve body, and this valve is linked with control axostylus axostyle, and this control axostylus axostyle one end is stretched out outside valve body and is positioned at control block; This control block is on the outside of valve body, and this control block has a pivot hole seat, connect apertures seat, wire outlet portion; This control unit includes a Returnning spring and controls rocking arm, and this control rocking arm has a linking department, and this linking department has connect apertures, and this connect apertures is sheathed on to control on axostylus axostyle, and separately this control rocking arm is provided with wire bond portion, positioning part and ejection part; This control motor is linked on the connect apertures seat of control block, and the front end of this control motor is provided with catch bar, and the front end of this catch bar relies on the ejection part of control rocking arm; This control flap by locking closure in control block; Control unit start can be made by this by control motor, and then carry out the aperture of control valve in valve body, engine can be made on the one hand to maintain the motion of normal idling, when the generator of engine power supply of its interlock under idling mode can be made to start simultaneously, because high-revolving idling required for the load that increases instantaneously still can normal operation and not stopping working, by above-mentioned structure, the overall volume of throttle valve can be avoided by this to maximize, simultaneously can the allocation project of summary engine intake, and then use effect of engine can be promoted.
