Abstract
A cylinder deactivation change apparatus including fuel supply parts supplying fuel into a first and second combustion chambers of a first and second cylinders, ignition parts igniting fuel-air mixture in the first and the second combustion chambers and a microprocessor. The microprocessor is configured to perform determining whether changing the operation mode is necessary, and controlling the fuel supply parts and ignition parts so as to ignite at first ignition timing before it is determined that changing the operation mode to the first mode is necessary, and so as to ignite at second ignition timing retarded in comparison with the first ignition timing and so as to supply the fuel into the first combustion chamber in a manner that causes a stratified charge combustion in the first combustion chamber, when it is determined that changing the operation mode to the first mode is necessary.
