Embodiment 1
[0031] Example 1: as Figure 1-4 As shown in the figure, a mixer assembly includes a mixer 1. A mixer pipe is provided on the mixer 1. The mixer pipe runs through the left end face and the right end face of the mixer 1. The pipe opening on the left end face of the mixer 1 is Mixed gas outlet, the pipe port on the right end face of the mixer 1 is the mixed gas inlet, the front end face of the mixer 1 is provided with two air inlets, the air inlet on the right side of the front end face of the mixer 1 is the EGR inlet 1-2, The air inlet on the left side of the front end face of the mixer 1 is the gas inlet 1-1, the right end face of the mixer 1 is provided with a mixer nozzle, and the mixer nozzle is provided with a flow guide structure.
[0032] The mixer nozzle is the elbow mixer nozzle 2, the bottom surface of the bending part inside the elbow mixer nozzle 2 is provided with a vertical lower guide structure 2-3, and the bending part inside the elbow mixer nozzle 2-3 The top ...
Embodiment 2
[0033] Example 2: as Figure 2-6 As shown, in this embodiment, the structure of the mixer is the same as that of Embodiment 1, wherein the mixer nozzle is a straight-tube mixer nozzle 3, and the interior of the straight-tube mixer nozzle 3 is provided with several sidewall guide structures 3-1 , the side wall guide structure 3-1 is a blade structure, and the side wall guide structure 3-1 is reduced from the right end to the left end to form an elongated blade structure.
[0034] A rotating fan blade can also be arranged in the nozzle of the mixer.
[0035] Working principle: Before the air takes over from the mixer to enter the mixer 1, the air passes through the upper diversion structure 2-2 and the lower diversion structure 2-3 or the side wall diversion structure 3-1 to disturb the disturbance. In the mixer 1, the EGR inlet 1- The EGR exhaust gas is introduced into 2 places, and the gas is introduced into the gas inlet 1-1. When the air reaches the mixer 1, it is in a turb...
