Description
Technical field
The utility model relates to the closure technical field of gasoline, DENG, internal-combustion engine, exactly relates to a kind of EFI variable vortex throttle body.
Background technique
Variable vortex fuel economizer (closure) is exactly to change a slice of the discoidal closure of traditional integral into three fan-shaped guide vanes, forms closure by three fan-shaped guide vanes, and its purpose is just for the above-mentioned defective of customer service tradition closure.During work, under the motor action of negative pressure, air-flow gets into and produces stronger eddy current swirling eddy under the water conservancy diversion of three fan-shaped guide vanes; So this closure can provide uniform air inlet, gas flow rate is very fast, and resistance is little; Crushing is low, and can form stronger eddy current, has the effect of eddy current supercharging; Thereby increased air inflow and suction pressure, oil, gas blending more evenly, fully can improve the oil gas rate fully of burning under square one; Increase motor output power, improved motor at low, the moment of torsion of medium speed and the susceptibility of throttle.Simultaneously, reduce oil consumption, reduce the discharging of CO, NOx, HC, reduce pollution air.
Publication number is CN1303315C, and the Chinese patent document that open day is on March 7th, 2007 discloses a kind of disc motor car engine, internal-combustion engine variable eddy current closure, and its disk is divided into fan-shaped closure identical more than three roads equably; The fan-shaped closure of per pass all is fixed on the throttle plate pin, and is rotated by 7 drivings of throttle valve drive dish, and this invention is owing to there is the above door in three roads; When opening simultaneously, there is the inclined-plane of water conservancy diversion leaf to get in motor action of negative pressure downstream along the per pass closure, and produces the eddy current rotation; Increase air inflow and suction pressure, air inlet is even, and flow velocity is fast; Resistance is little, and fuel combustion is complete, reduces environmental pollution; Increase engine horsepower; Practice thrift oil plant, and can improve moment of torsion and the sensitivity of throttle of motor when low, middling speed, the intake manifold length that can shorten available engine is to reduce the intake resistance of motor under maximum load work.
In the above-mentioned patent documentation; One side that the fan-shaped closure of per pass rotates all is designed with guide vane; What the guide vane moulding was adopted is the gradual change type channelization angle; The sectional shape of guide vane is triangular in shape substantially, and that limit towards the closure center in the triangle is the circular arc (see figure 7), and concrete blade structure and assembling situation see that Fig. 6 is to shown in Figure 9.Though the variable vortex throttle body of this kind blade structure can produce the eddy current rotation; Increase the air inflow and the suction pressure of motor; Produce effects such as fuel-economizing; But the variable vortex throttle body of in engineering practice, finding this structure has following shortcoming: under the effect of guide vane, air can produce the eddy current rotation before getting into motor, but because its guide vane sectional shape is triangular in shape substantially; That limit towards the closure center in the triangle is a circular arc; Such structural type will certainly produce a spot of backflow effeet, though more effective than the air inlet of the throttle body of conventional one-piece disc type blade, also do not given play to the effect of variable vortex throttle body.
The model utility content
For solving the problems of the technologies described above; The utility model provides a kind of EFI variable vortex throttle body; The utility model can be brought into play the fuel-economizing effect of variable vortex throttle body in bigger effect ground, and can effectively avoid three guide vanes occurring in the interference problem between the guide vane in the rotary course synchronously.
The utility model is realized through adopting following technical proposals:
A kind of EFI variable vortex throttle body; Comprise fan-shaped closure identical more than three roads; One side that the fan-shaped closure of per pass rotates is equipped with guide vane; What the guide vane moulding was adopted is the gradual change type channelization angle, and the sectional shape of guide vane is triangular in shape, it is characterized in that: that limit towards the closure center in the triangle is a straight flange.
Cooperate through the inclined-plane between the fan-shaped closure of per pass, the angle on said inclined-plane is 15 degree.
The sharp corner that on the fan-shaped closure of per pass, is positioned at the closure center portion has chamfering.
Described fan-shaped closure is three.
Compared with prior art, the beneficial effect of the utility model shows:
1, in the utility model; Be straight flange towards that limit at closure center in the triangle; Such structural type is than the CN1303315C patent of invention, when closure is worked; The channelization angle of straight flange structure can not produce backflow effeet, can bring into play to bigger effect the effects such as fuel-economizing of variable vortex throttle body.
2, in the utility model; Cooperate through the inclined-plane between the fan-shaped closure of per pass; The angle on said inclined-plane is 15 degree; With respect to the CN1303315C patent of invention be disclosed 10 degree of the existing technology of representative, can further improve the cooperation tightness between the fan-shaped closure of per pass, the matching gap between the blade is littler; Full cut-off leakage rate at the variable vortex throttle body of assembling condition is littler than the full cut-off leakage rate of CN1303315C patent of invention throttle body, the performance that has directly improved variable vortex throttle body effect.
3, in the utility model; The sharp corner that on the fan-shaped closure of per pass, is positioned at the closure center portion has chamfering; Can effectively avoid three guide vanes in the rotary course interference problem between the guide vane taking place synchronously; Can better satisfy the requirement of motor to throttle body full cut-off leakage rate; Because the variable vortex throttle body after improving can effectively be avoided the interference problem between the blade, thereby the matching gap between the blade can further reduce, and the variable vortex throttle body of the utility model blade shape construction can satisfy the technical parameter requirement of available engine to throttle body fully.
