Outside.
The second flow channel being connected with Cooling of Cylinder Head chamber, second flow channel and cylinder body cooling chamber interval are provided in cylinder body 1
It opens.That is, the inside of cricoid cylinder body cooling chamber is arranged in cylinder holes, and the outer of cricoid cylinder body cooling chamber is arranged in second flow channel
Side, to prevent the heat of cylinder holes from having an impact to the cooling fluid in second flow channel.
Fig. 2,3 and 5 schematically show the structure of second flow channel 22, and entering cooling fluid can be by second flow channel 22
It is conveyed to Cooling of Cylinder Head chamber.Since the other side of cylinder body cooling chamber 12, the heat generated at cylinder holes is arranged in flow-guiding structure

As shown in Fig. 2,3 and 5, the meet of sprue 24, second flow channel 22 and first runner 21 is provided with current stabilization
Chamber, current stabilization chamber have biggish volume.The biggish current stabilization chamber of volume can reduce the flow velocity of cooling fluid, so as to make cooling fluid
State tend to be steady.Since when the flow velocity of cooling fluid is excessively high, the resistance entered in thinner runner is larger, cooling stream
Body but can cannot more tend to flow into the bigger runner of circulation area it is anticipated that shunt as design.Thus
And current stabilization chamber is set so that cooling fluid can according to the circulation area of second flow channel and the circulation area of first runner, according to
Shunting, cylinder body is cooled down with cylinder cap respectively as desired design, thus ensure that cylinder body and cylinder cap energy effective temperature-reducing,
It ensure that the leakproofness and safety of cylinder.
