摘要：
A controller performs switching between a compression ignition mode in which compression ignition combustion is performed to operate an engine body, and a spark ignition mode in which spark ignition combustion is performed to drive a spark plug to ignite and combust an air-fuel mixture in a cylinder. The controller reduces an EGR ratio to be lower than an EGR ratio set in the compression ignition mode to operate the engine body in a transitional mode in which the compression ignition combustion is performed in switching from the spark ignition mode to the compression ignition mode.
