項記載の可変気筒式内燃機関。[Claims for Utility Model Registration] 1. A first cylinder group that is always in operation, a second cylinder group that is inactive depending on the engine condition, and an intake passage that communicates the intake sides of these first and second cylinder groups with the atmosphere. and the first and second
first and second exhaust passages that communicate with the exhaust side of the cylinder group, an exhaust recirculation passage that communicates the intake passage with the first or second exhaust passage, and a recirculation control valve that opens and closes the exhaust recirculation passage. The variable cylinder internal combustion engine is characterized in that the degree of opening of the recirculation control valve is relatively small when the first and second cylinder groups are in operation, and relatively large when only the first cylinder group is in operation. . 2. First and second control mechanisms are provided for controlling the opening and closing of the reflux control valve, the first control mechanism controlling the opening and closing of the reflux control valve when the first and second cylinder groups are in operation, and the second control mechanism for controlling the opening and closing of the reflux control valve. Utility model registration claim 1, characterized in that the recirculation control valve is controlled to open and close when only the first cylinder group is in operation.
