| description | To adjust a wall temperature of a combustion chamber with high responsiveness in accordance with a load of an engine.SOLUTION: An engine system 1 includes an engine 10, a circulation device 91 for circulating cooling water to a water jacket 20, and a controller (ECU 100). The circulation device includes a radiator flow passage 53 including a heat exchanger (radiator 27), a bypass flow passage 51, a flow control device (cooling water control valve 4), and a thermostat valve 28. The engine switches between first combustion in which an air-fuel mixture is burned without forcible ignition of an ignition device and second combustion in which the air-fuel mixture is burned by forcible ignition of the ignition device. The controller controls the flow control device so that a flow rate of the cooling water flowing in the water jacket is adjusted in accordance with a load by closing the radiator flow passage and adjusting a flow rate of the cooling water flowing through the bypass flow passage when the engine carries out the first combustion.SELECTED DRAWING: Figure 4
【課題】エンジンの負荷に応じて、燃焼室の壁温を高い応答性で調整する。【解決手段】エンジンシステム１は、エンジン１０と、ウォータジャケット２０に冷却水を循環させる循環装置９１と、制御器（ＥＣＵ１００）と、を備え、循環装置は、熱交換器（ラジエータ２７）を含むラジエータ流路５３と、バイパス流路５１と、流量調整装置（冷却水制御バルブ４）と、サーモスタット弁２８と、を有する。エンジンは、点火装置の強制点火無しに混合気が燃焼する第１燃焼と、点火装置の強制点火によって混合気が燃焼する第２燃焼とを切り替える。制御器は、エンジンが第１燃焼を実行している場合に、ラジエータ流路を閉じかつ、バイパス流路を流れる冷却水の流量を調整することによって、ウォータジャケットを流れる冷却水の流量が、負荷に応じて調整されるよう、流量調整装置を制御する。【選択図】図４ |
