[0008] Furthermore, a gas guide hole is provided at the gas outlet end of the gas channel, and a plurality of gas outlets are sequentially spaced apart along the length direction of the gas guide hole.

[0009] Furthermore, the length direction of the air guide hole extends around the axial center line direction of the air channel.

[0010] Furthermore, with the axis direction of the air channel as the X-axis, the plane perpendicular to the X-axis as the YOZ plane, the angle between the lines connecting the two ends of the air guide hole and the projection of the axis of the air channel on the YOZ plane is α, wherein 150°<α<180°.

[0011] Furthermore, the throttle body is also provided with a fuel channel connected to the air channel, the fuel inlet end of the fuel channel is connected to the fuel delivery pipeline, and the fuel outlet end is connected to the air channel, so as to introduce fuel into the air channel to form a mixture.

[0012] Furthermore, a control valve is provided on the throttle body, and the control valve is used to control the on-off of the gas channel.

[0013] On the other hand, the present invention further provides an engine, comprising the novel throttle body described in any one of the above items.

[0014] Beneficial effects of the present invention: The novel throttle body and engine provided by the present invention have simple structure and reasonable design. By setting a plurality of air outlets, the fuel gas is dispersed into the air passage, thereby achieving the purpose of improving the mixing uniformity of the fuel gas and air.

[0024] like Figure 1-3 As shown, the present invention provides a new throttle body, including a throttle body, the throttle body having an air passage 110 and a gas passage 120 communicating with the air passage 110. The inlet end of the gas passage 120 is communicated with the gas delivery pipeline, and the outlet end is communicated with the air passage 110. Specifically, the inlet end of the gas passage 120 is communicated with the gas delivery pipeline through a gas connector 300. In the working state, the gas enters the air passage 110 through the gas delivery pipeline and the gas passage 120, mixes with the air in the air passage 110, and finally enters the engine cylinder.

[0025] like Figure 1-3 As shown, the outlet end of the gas channel 120 is provided with a plurality of gas outlets 121. In the working state, the gas enters the air channel 110 from the plurality of gas outlets 121, so that the gas is dispersed into the air channel 110, thereby achieving the purpose of making the gas and air mix more evenly, thereby achieving the purpose of improving combustion efficiency, reducing fuel consumption and emissions. It should be noted that the plurality of gas outlets 121 can be arranged in sequence along the axis of the air channel 110, or can be arranged in sequence around the axis of the air channel 110. Figure 2 , 3 As shown, in this embodiment, six air outlets 121 are provided.

[0026] Since the multiple gas outlets 121 are arranged in sequence along the axis direction of the air channel 110, the gas still enters the air channel 110 from a single direction on one side of the air channel 110, resulting in poor mixing uniformity of the gas and air. Figure 1-3 As shown, in this embodiment, a plurality of air outlets 121 are arranged in sequence and spaced apart in the direction of the axis of the air passage 110, so that the gas enters the air passage 110 from multiple directions on one side of the air passage 110, thereby making the mixing uniformity of the gas and air higher.

[0027] like Figure 1-3 As shown, the gas outlet end of the gas channel 120 is provided with an air guide hole 122, and a plurality of air outlets 121 are sequentially arranged at intervals along the length direction of the air guide hole 122. It should be noted that the length direction of the air guide hole 122 can extend along the axis direction of the air channel 110 or around the axis direction of the air channel 110.

[0028] Since the length direction of the air guide hole 122 can extend along the axis direction of the air channel 110, and the multiple air outlets 121 are arranged in sequence along the axis direction of the air channel 110, the gas still enters the air channel 110 from a single direction on one side of the air channel 110, resulting in poor mixing uniformity of the gas and air. Figure 2-3 As shown, in this embodiment, the length direction of the air guide hole 122 extends around the axial direction of the air channel 110, and the multiple air outlets 121 are arranged in sequence at intervals around the axial direction of the air channel 110, so that the gas enters the air channel 110 from multiple directions on one side of the air channel 110, thereby making the mixing uniformity of the gas and air higher.

[0029] like Figure 3As shown, the axis direction of the air channel 110 is the X-axis, the plane perpendicular to the X-axis is the YOZ plane, and the angle between the lines connecting the two ends of the air guide hole 122 and the projection of the axis of the air channel 110 on the YOZ plane is α, where 150°<α<180°.

[0030] like Figure 1 As shown, the throttle body 100 is also provided with a fuel channel connected to the air channel 110. The oil inlet end of the fuel channel is connected to the fuel delivery pipeline, and the oil outlet end is connected to the air channel 110, so as to introduce the fuel into the air channel 110 to form a mixture. The mixture eventually enters the cylinder to burn and do work, thereby achieving the purpose of converting internal energy into mechanical energy.

[0031] Specifically, the air inlet end of the fuel channel is connected to the fuel delivery pipeline through the fuel joint 400. In the working state, the fuel enters the air channel 110 through the fuel delivery pipeline and the fuel channel, mixes with the air in the air channel 110, and finally enters the engine cylinder, so as to achieve the purpose of providing the engine with a mixture of fuel and air through the throttle provided by this embodiment, and also providing the engine with a mixture of gas and air through the throttle provided by this embodiment, thereby achieving the purpose of improving the adaptability of the throttle provided by this embodiment.

[0032] Preferably, a fuel atomization device 500 is provided on the throttle body 100, and the oil inlet end of the fuel atomization device 500 is connected and communicated with the fuel connector 400, and the oil outlet end is communicated with the fuel channel, so that after the fuel is atomized, it is introduced into the air channel 110 through the fuel channel, thereby achieving the purpose of improving the mixing effect of fuel and air.

[0033] like Figure 1-3 As shown, the throttle body 100 is provided with a control valve 200, and the control valve 200 is used to control the on-off of the gas passage 120. In the working state, the control valve 200 is opened to make the gas passage 120 unblocked, so as to achieve the purpose of allowing the gas to enter the air passage 110 through the gas passage 120. In the non-working state, the control valve 200 is closed to disconnect the gas passage 120, so as to achieve the purpose of preventing the gas from entering the air passage 110 through the gas passage 120.

[0034] The present invention also provides an engine, comprising the novel throttle body described in any of the above embodiments.

[0035] It should be noted that, since the engine includes the new throttle body in any of the above-mentioned embodiments, the engine has the same technical effects as the new throttle body in the above-mentioned embodiments, which will not be repeated here.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
