Abstract
A spark-ignition engine is provided. The engine includes an engine body, a fuel injection valve, an ignition plug, an EGR introduction system, and a controller for operating the engine body by controlling the fuel injection valve, the ignition plug, and the EGR introduction system. The controller controls to combust mixture gas by compressing to self-ignite within a compression self-ignition combustion applying range, and to combust the mixture gas by a spark-ignition using the ignition plug within a spark-ignition combustion applying range. Substantially throughout the spark-ignition combustion applying range, the controller controls the EGR introduction system to introduce cooled EGR gas, and within the compression self-ignition applying range, the controller controls the EGR introduction system to introduce hot EGR gas. The controller controls the EGR introduction system to introduce the hot EGR gas and the cooled EGR gas within a low engine load part of the spark-ignition combustion applying range.
