Or similar label represents same or similar element or has the element of same or like function.Retouch below with reference to accompanying drawing
The embodiment stated is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
As shown in Figures 1 to 5, a kind of engine cylinder-body cooling flow guide system is embodiments provided, including cylinder body
1, cylinder body 1 is provided with water inlet 14 and outlet (mark), in cylinder body 1, is provided with cylinder barrel 11, wherein, water inlet 14 is close
The exhaust side 15 of cylinder body 1, outlet is near the air inlet side 16 of cylinder body 1；Cooling flow guide system also includes mozzle 2, mozzle 2
One end is fixing with water inlet 14 to be connected, and the other end of mozzle 2 is blind end 23, and is fixed on cylinder body 1 relative to water inlet 14
Side；Pod apertures 221 it is provided with on the sidewall of mozzle 2.Engine cooling water, after water pump pressurizes, flows from water inlet 14
Entering mozzle 2, and then full mozzle 2, cooling water enters cylinder body water jacket 13 from pod apertures 221, cools down cylinder barrel 11.
It will be appreciated by persons skilled in the art that pod apertures 221 can be multiple, and horizontal along the sidewall of mozzle 2
To arrangement, thus can realize synthermal cooling water and multiple cylinder barrels 11 be cooled down simultaneously, it is to avoid newly entering cooling water
Temperature is low, and the cooling water temperature having been enter into is high, the problem to cylinder barrel 11 cooling effect difference；Cooling water from mozzle 2 out after,
Cylinder barrel 11 exhaust side 15 is cooled down by major part, and fraction enters corresponding air inlet side 16 by cylinder body 1 rear end cylinder body water jacket 13
Cylinder body 1 inner chamber in, the air inlet side 16 of cylinder body 1 is cooled down, water (flow) direction, thus can as shown in the direction of arrow in Fig. 1
It is weaker than the cooling of exhaust side 15 realizing the cooling of cylinder body 1 air inlet side 16, and then air inlet side 16 and exhaust side 15 can be balanced
Temperature.
As shown in Figure 2 to Figure 3, further, mozzle 2 includes that main body 22 and construction section 21, main body 22 are semicircular pipe
