Abstract:
1. A cylinder direct injection type internal combustion engine, comprising: a fuel injection device configured to directly inject a first octane-value fuel and a second octane-value fuel into a combustion chamber, the second octane-value fuel having an octane value larger than an octane value of the first octane-value fuel; and a controller programmed to perform a first operation mode, wherein, in the first operation mode, the first octane-value fuel is injected from the fuel injection device, and the second octane-value fuel is injected from the fuel injection device toward an ignition flame formed by self-ignition combustion of the first octane-value fuel, so as to cause flame propagation and combustion of the second octane-value fuel.
