Description
Technical field
The invention relates to a kind of throttle valve control structure of engine, espespecially a kind of avoiding maximized the overall volume of throttle valve, but the allocation project of summary engine intake simultaneously, and then can promote the throttle-valve structure of engine of the use effect of engine.
Background technique
Cooperatively interacting between the design of air inlet pipeline and engine is very important for engine, for example, engine is at a slow speed or when claiming the slow-speed of revolution, the sectional area of its needed air inlet pipeline is less, length is longer, so can be conducive to improve 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, its required air inlet pipeline sectional area is large, length is shorter, so can reduce flow resistance, thereby be conducive to the lifting of intake efficiency, and then improve combustion process, promotes horsepower.
See also shown in Figure 1, the function mode of engine 1, to 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 the mist of oil shape with the extraneous fresh air that is entered by throttle valve (variable air inlet member) 2, and send Ignition signal to spark coil 14 by electronic control unit 11, making 15 of ignition mechanisms (spark plug) fight lights this mist of oil, make by this piston 16 reciprocating, 16 band dynamic crankshafts 17 of this piston rotate, and produce by this power.
Yet engine 1 is to operate in low-speed running (idling) mode in travelling state lower time when vehicle is non-, avoids by this engine 1 flame-out.This engine 1 is when idling operates, electronic control unit 11 can reduce the amount of fuel via injection apparatus 12 ejections, needed extraneous fresh air of while, by being located at 21 supplies of the other idle speed air admission bypass of variable air inlet member 2, this idle speed air admission bypass 21 is provided with electronic control valve 211, by the extraneous fresh air inlet of the control of this electronic control valve 211, make by this engine 1 can keep fixing idling running.
Known engine 1 by on 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 engine 1 can keep fixing idling running, flame-out and reduce the purpose of fuel consume to reach engine 1.As shown in Figure 2, when engine 1 links a generator 3 or other power in addition, the generator 3 that should link in addition is just can be activated when operating in engine 1 in idling, this moment, meeting undoubtedly caused the load of engine 1 significantly to increase, this engine 1 be for can allow these external generator 3 normal operations, the 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 of commonly using obviously can't in response to, when engine 1 operates in idling, load moment increases, and must promote air inflow simultaneously so that the demand that engine 1 rotating speed improves.Therefore how to provide a kind of engine 1 that makes can be because of the control structure of the throttle valve 2 of non-loaded idling and load idle speed air admission amount, the real problem of demanding urgently overcoming for present vehicle manufacturer.
Summary of the invention
Because known throttle valve can't 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 to provide a kind of throttle valve control structure of engine, this throttle valve include at least valve body, valve, control block, control unit, control motor and control flap; This valve is to be located in valve body, and this valve links to be had control axostylus axostyle, this controls axostylus axostyle one end to stretch out valve body to be positioned at control block outward; This control block is on the outside of valve body, and this control block has a pivot hole seat, connect apertures seat, wire outlet section; This control unit includes a Returnning spring and controls rocking arm, and this controls rocking arm has a linking department, has connect apertures on this linking department, and this connect apertures is to be sheathed on to control on axostylus axostyle, and separately this control rocking arm is provided with wire bond section, positioning part and ejection part; This control motor is to be 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 is to rely on the ejection part of controlling rocking arm; This control flap by locking closure on control block; Can make the control unit start by controlling motor by this, and then come the aperture of control valve in valve body, can make on the one hand engine keep normal idling motion, in the time of can making simultaneously the generator startup of engine power supply use of its interlock under idling mode, because the required high-revolving idling of load that moment increases still can not stopped working in normal operation, by above-mentioned structure, can avoid by this overall volume of throttle valve is maximized, but the allocation project of summary engine intake simultaneously, and then can promote the use effect of engine.
