Zusammenfassung:	PROBLEM TO BE SOLVED: To provide technology accelerating vaporization of fuel spray by controlling reverse flow exhaust gas reversely flowing into a combustion chamber from an exhaust port in an exhaust control device for an internal combustion engine. SOLUTION: This device is provided with a fuel injection valve 12 directly injecting fuel spray into the combustion chamber 5 toward an exhaust gas flow out side in the combustion chamber 5, and an exhaust valve 9 opening and closing an opening part of an exhaust port 7 extending from an opening part opening at an exhaust gas flow out side upper part of the combustion chamber 5. When fuel spray is injected by the fuel injection valve 12, the exhaust valve 9 is opened to make exhaust gas reversely flow, and to make reverse flow exhaust gas reside at the exhaust gas flow out side in the combustion chamber 5. Residing reverse flow exhaust gas and fuel spray reaching to the exhaust gas flow out side of the combustion chamber 5 are collided. COPYRIGHT: (C)2009,JPO&INPIT
