ン。 In a variable compression ratio engine that changes the compression ratio of each cylinder depending on the operating state of the engine, the combustion chamber of the cylinder and the intake passage of the cylinder in the intake stroke when the cylinder is in the compression stroke. A communicating passage is provided, and the passage is opened when the compression ratio in the combustion chamber of the cylinder in the compression stroke becomes higher than a predetermined value preset according to the operating state of the engine. A variable compression ratio engine characterized by being provided with a valve that sets the compression ratio to a predetermined value.
