| description | To prevent the local ebullition (a local abnormal temperature rise of a cylinder block) of cooling water without impairing a warmup promotion effect, in a two-system cooling type internal combustion engine which does not make the cooling water flow to a block jacket at a warmup operation.SOLUTION: Water is made to slightly flow to block jackets 6 (65, 66) at a warmup operation via a leak passage. A drill passage 69 for making cooling water flow to a head jacket 7 from a constricted part 66a of a block jacket intake-side portion 66 is opened at an inter-bore part 68. Also, the block jacket intake-side portion 66 and the head jacket 7 communicate with each other via a small-diameter ventilation hole 74. By a negative pressure effect of the head jacket 7, the cooling water can be made to flow to the head jacket 7 from the drill passage 69 and the ventilation hole 74.SELECTED DRAWING: Figure 7
【課題】暖機運転時には冷却水をブロックジャケットに流さない２系統冷却式内燃機関において、暖機促進効果を損なうことなく、冷却水の局部沸騰（シリンダブロックの局所的異常高温化）を防止する。【解決手段】ブロックジャケット６（６５，６６）には、リーク通路を介して暖機運転時にも僅かながら通水されている。ボア間部６８に、ブロックジャケット吸気側部分６６のくびれ部６６ａから冷却水をヘッドジャケット７に流すドリルドパッセージ６９が空いている。また、ブロックジャケット吸気側部分６６とヘッドジャケット７は、小径の空気抜き穴７４を介して連通している。ヘッドジャケット７の負圧効果により、冷却水をドリルドパッセージ６９及び空気抜き穴７４からヘッドジャケット７に通水できる。【選択図】図７ |
