[0033] One end of each branch pipe is used to communicate with each cylinder of the engine, and the other end of each branch pipe is arranged opposite to at least one diversion notch, so that when the water level of the condensed water in the water storage tank 300 is located at the diversion notch, part of the condensed water passes through the corresponding diversion notch and is transmitted to a cylinder through a branch pipe.

[0034] The size of each guide notch is consistent.

[0035] That is, the condensed water transmitted by the input end 110 is first transmitted to the water tank 300, and the water tank 300 is used to store the condensed water, so that the condensed water forms a circulation along the length direction of the water tank 300 at the first time. When the water level of the condensed water reaches a certain height, the diversion notches of the same size are used to allow the condensed water to pass through the corresponding diversion notches at the same time and enter the corresponding branch pipes for diversion, so that the condensed water content entering each cylinder is consistent, thereby solving the problem of uneven condensed water transmission in the prior art, ensuring that the condensed water content flowing into multiple cylinders is consistent, and avoiding excessive condensed water in a certain cylinder, affecting the combustion of a certain cylinder, causing unstable combustion, and affecting the technical problem of engine performance.

[0036] It should be noted that, in this embodiment, the cylinder block of the engine belongs to the conventional technology in the field and is not shown in the drawings.

[0037] Specifically, to facilitate understanding of the present case, in the present embodiment, the multiple branches may be four branches, namely a first branch 400, a second branch 500, a third branch 600 and a fourth branch 700. It should be noted that the four branches in the present embodiment are not intended to limit the number of branches, but may also include other numbers, which are not specifically described herein.

[0038] In order to increase the circulation speed of condensed water, in some preferred embodiments, each edge portion of the special-shaped baffle 200 is arranged opposite to each side wall portion of the main pipe 100, so that the water storage tank 300 forms an annular structure, which can be a circular ring, and a part of the multiple guide notch portions are arranged on the first edge portion 210 of the special-shaped baffle 200, and another part of the guide notch portions are arranged on the second edge portion 220 of the special-shaped baffle 200, and the first edge portion 210 and the second edge portion 220 are arranged opposite to each other.

[0039] Specifically, the diversion device includes a plurality of first diversion notch portions 230 and a plurality of second diversion notch portions 240, the first diversion notch portions 230 and the second diversion notch portions 240 are respectively arranged on the first edge portion 210 and the second edge portion 220, each first diversion notch portion 230 and each second diversion notch portion 240 are arranged opposite to each other, and one end of each branch pipe close to the water storage tank 300 is respectively arranged opposite to a first diversion notch portion 230 and a second diversion notch portion 240.

[0040] That is to say, one end of the first branch pipe 400, the second branch pipe 500, the third branch pipe 600 and the fourth branch pipe 700 close to the water storage tank 300 is respectively arranged opposite to a first guide notch portion 230 and a second guide notch portion 240, and one end of the first branch pipe 400, the second branch pipe 500, the third branch pipe 600 and the fourth branch pipe 700 is respectively connected to a first guide notch portion 230 and a second guide notch portion 240, so that the condensed water flowing into each branch pipe can be transmitted by the corresponding first guide notch portion 230 and the second guide notch portion 240 at the same time, thereby greatly improving the transmission speed of the condensed water and ensuring the reasonable operation of each cylinder body.

[0041] In some other preferred embodiments, the second branch pipe 500 and the third branch pipe 600 are arranged between the first branch pipe 400 and the fourth branch pipe 700, the fourth branch pipe 700 is arranged on the side close to the input end 110, and the first branch pipe 400, the second branch pipe 500, the third branch pipe 600 and the fourth branch pipe 700 are all fixedly connected to the main pipe 100.

[0042] In summary, the present embodiment provides a flow diversion device for engine condensed water, by arranging a special-shaped baffle 200 with a plurality of diversion notches in the main pipe 100, and a gap is provided between the special-shaped baffle 200 and the inner wall of the main pipe 100 to form a water storage tank 300 for accommodating condensed water, that is, the condensed water transmitted by the input end 110 is first transmitted to the water storage tank 300, and the condensed water is stored in the water storage tank 300, so that the condensed water forms a circulation along the length direction of the water storage tank 300 at the first time.
