[0028] As Figures 1-3The utility model provides a novel throttle body, including throttle main part 100, throttle main part 100 has air passage 110 and with air passage 110's gas passage 120. The air inlet end of gas passage 120 is communicated with gas delivery pipeline, and the air outlet end is communicated with air passage 110. Specifically, the air inlet end of gas passage 120 is communicated with gas delivery pipeline through gas joint 300. In working condition, gas enters air passage 110 through gas delivery pipeline and gas passage 120, mixes with the air in air passage 110, and finally enters the cylinder of engine.

[0029] As Figures 1-3 The air outlet end of gas passage 120 is provided with a plurality of gas outlets 121, and in working condition, gas enters air passage 110 from a plurality of gas outlets 121, so that gas is dispersed into air passage 110, thereby achieving the purpose of making gas and air mix more uniformly, and further achieving the purposes of improving combustion efficiency, reducing fuel consumption and emission. It should be noted that the plurality of gas outlets 121 can be sequentially and spacedly arranged along the axial direction of air passage 110, or can be sequentially and spacedly arranged around the axial direction of air passage 110. As Figure 2 、 3 In this embodiment, the gas outlet 121 is provided with six.

[0030] Since the plurality of gas outlets 121 are sequentially and spacedly arranged along the axial direction of air passage 110, gas still enters air passage 110 from a single direction on one side of air passage 110, resulting in poor uniformity of gas and air mixing. Therefore, as Figures 1-3 In this embodiment, the plurality of gas outlets 121 are sequentially and spacedly arranged around the axial direction of air passage 110, so that gas enters air passage 110 from a plurality of directions on one side of air passage 110, thereby achieving high uniformity of gas and air mixing.

[0031] As Figures 1-3 The air outlet end of gas passage 120 is provided with a gas guide hole 122, and the plurality of gas outlets 121 are sequentially and spacedly arranged along the length direction of the gas guide hole 122. It should be noted that the length direction of the gas guide hole 122 can extend along the axial direction of air passage 110, or can extend around the axial direction of air passage 110.

[0032] Since the length direction of the gas guide hole 122 can extend along the axial direction of air passage 110, and the plurality of gas outlets 121 are sequentially and spacedly arranged along the axial direction of air passage 110, gas still enters air passage 110 from a single direction on one side of air passage 110, resulting in poor uniformity of gas and air mixing. Therefore, as Figures 2-3As shown in the embodiment, the length direction of the air guide hole 122 extends around the axial line direction of the air passage 110, and the plurality of air outlets 121 are sequentially and spacedly arranged around the axial line direction of the air passage 110, so that the fuel gas enters the air passage 110 from multiple directions on one side of the air passage 110, and the mixing uniformity of the fuel gas and the air is high.

[0033] As shown in the embodiment, the length direction of the air guide hole 122 extends around the axial line direction of the air passage 110, and the plurality of air outlets 121 are sequentially and spacedly arranged around the axial line direction of the air passage 110, so that the fuel gas enters the air passage 110 from multiple directions on one side of the air passage 110, and the mixing uniformity of the fuel gas and the air is high. Figure 3 As shown in the embodiment, the length direction of the air guide hole 122 extends around the axial line direction of the air passage 110, and the plurality of air outlets 121 are sequentially and spacedly arranged around the axial line direction of the air passage 110, so that the fuel gas enters the air passage 110 from multiple directions on one side of the air passage 110, and the mixing uniformity of the fuel gas and the air is high.

[0034] Figure 1 As shown in the embodiment, the length direction of the air guide hole 122 extends around the axial line direction of the air passage 110, and the plurality of air outlets 121 are sequentially and spacedly arranged around the axial line direction of the air passage 110, so that the fuel gas enters the air passage 110 from multiple directions on one side of the air passage 110, and the mixing uniformity of the fuel gas and the air is high.

[0035] Specifically, the air inlet end of the fuel passage is communicated with the fuel delivery pipeline through the fuel joint 400. In the working state, the fuel enters the air passage 110 through the fuel delivery pipeline and the fuel passage, mixes with the air in the air passage 110, and finally enters the engine cylinder, so that the purpose of providing the mixture of fuel and air to the engine through the throttle valve provided in the embodiment and providing the mixture of fuel gas and air to the engine through the throttle valve provided in the embodiment can be achieved, and the purpose of improving the adaptability of the throttle valve provided in the embodiment can be achieved.

[0036] Preferably, the throttle valve body 100 is provided with a fuel atomization device 500, the oil inlet end of the fuel atomization device 500 is connected with and communicated with the fuel joint 400, and the oil outlet end is communicated with the fuel passage, so that the fuel is atomized and then introduced into the air passage 110 through the fuel passage, thereby achieving the purpose of improving the mixing effect of the fuel and the air.
