摘要： A control device for a multicylinder spark-ignition engine includes a flow path switching unit for switching intake and exhaust flow paths between a two-cylinder interconnect configuration and an independent cylinder configuration and an air-fuel ratio control unit. In a low-load, low-speed operating range, the flow path switching unit switches the engine to the two-cylinder interconnect configuration, and the air-fuel ratio control unit produces a lean mixture having an air-fuel ratio larger than the stoichiometric air-fuel ratio by a specific amount in preceding cylinders by injecting fuel thereinto and an air-fuel ratio approximately equal to the stoichiometric air-fuel ratio in following cylinders by supplying fuel together with burned gas of a lean mixture state discharged from the preceding cylinders into the following cylinders to perform combustion in special operation mode. At engine startup, the flow path switching unit switches the engine to the independent cylinder configuration to perform combustion in normal operation mode.

摘要： A control device switches an engine between normal operation mode and special operation mode. In the normal operation mode, an independent cylinder configuration is formed to produce combustion independently in individual cylinders. In the special operation mode, a two-cylinder interconnect configuration is formed so that burned gas discharged from preceding cylinders currently in an exhaust stroke is introduced into following cylinders currently in an intake stroke through intercylinder gas channels, a lean mixture having a high air-fuel ratio is combusted in the preceding cylinders, and a mixture produced by supplying fuel to the burned gas is combusted in the following cylinders. When the engine is switched between the special operation mode and the normal operation mode, the control device selects transitional operation mode, in which the two-cylinder interconnect configuration is formed, and interrupts combustion in the preceding cylinders while producing combustion in the following cylinders by compression ignition.
