| description | To improve the cooling performance of EGR gas, in an internal combustion engine in which an EGR passage is provided in the inside of a cylinder head and cooling water is cooled.SOLUTION: On a cylinder head 2, a sub water jacket 6 for cooling an EGR passage 5 in a head is formed, in addition to a main water jacket 4. An outlet portion 12 of the main water jacket 4 and a heater core 20 are connected by a heater feeding pipe 21, and temperature-decreased cooling water flows into the sub water jacket 6 through the heater core 20. Therefore, the cooling performance of an EGR gas can be improved. When the water pressure of the main water jacket 4 exceeds a set value, the cooling water flows into the sub water jacket 6 through a bypass passage 24, and returns from a bypass return passage 19 to a water pump 15.SELECTED DRAWING: Figure 1
【課題】シリンダヘッドの内部にＥＧＲ通路を設けてこれを冷却水で冷却する内燃機関において、ＥＧＲガスの冷却性能を向上させる。【解決手段】シリンダヘッド２に、メインウォータジャケット４の他に、ヘッド内ＥＧＲ通路５を冷却するためのサブウォータジャケット６が形成されている。メインウォータジャケット４の出口部１２とヒータコア２０とがヒータ送り管２１によって接続されており、ヒータコア２０を経由して降温した冷却水がサブウォータジャケット６に流入する。従って、ＥＧＲガスの冷却性能を向上できる。メインウォータジャケット４の水圧が設定値を越えると、冷却水はバイパス通路２４を経由してサブウォータジャケット６に流入し、バイパス戻り通路１９からウォータポンプ１５に戻る。【選択図】図１ |
