Abstract:
A preparation control for suppressing fluctuation of an output torque of the engine at the time of executing switching operation from the whole cylinder operation to the partial cylinder operation is executed when having made a switching request from the whole cylinder operation to the partial cylinder operation, the valve operation phase is fixed to a predetermined phase before executing the switching operation, and the cylinder deactivation mechanism is controlled so as to execute the switching operation at a target switching time which is prefixed by corresponding to the predetermined phase. The target switching time is previously set to a timing at which abnormal noises are not generated, by corresponding to the valve operation phase fixed to the predetermined phase.

Claim (Index 1):
A control method of an internal combustion engine which comprises a plurality of cylinders, a valve operation phase variable mechanism configured to change a valve operation phase of at least one of an intake valve and an exhaust valve provided in each of the plurality of cylinders, and a cylinder deactivation mechanism configured to perform switching between partial cylinder operation in which a part of the plural cylinders is operated and whole cylinder operation in which all of the cylinders are operated, comprising steps of:\n (a) executing, by a computer, a preparation control for suppressing fluctuation of an output torque of the engine at a time of executing switching operation from the whole cylinder operation to the partial cylinder operation when a switching request from the whole cylinder operation to the partial cylinder operation is made; (b) fixing, by a computer, the valve operation phase to a predetermined phase before executing the switching operation; and (c) outputting, by a computer, switching command signal to the cylinder deactivation mechanism based on a target switching time which is prefixed in accordance with the predetermined phase so as to execute the switching operation.
