    摘要： A controller for an internal combustion engine (10) is configured, when the speed of combustion of a fuel in a cylinder (14') changes as the property of the fuel injected from a fuel injection valve (26) changes, to change a combustion limit excess air ratio that is a target value of a fuel injection amount feed forward control according to a first relationship that the combustion limit excess air ratio increases as the speed of combustion of the fuel in the cylinder (14') increases. The controller is also configured, when the speed of combustion of the fuel in the cylinder (14') changes as the property of the fuel injected from the fuel injection valve (26) changes, to change the value of a combustion limit combustion speed parameter that is the target value of a fuel injection amount feedback control according to a second relationship that the speed of combustion of the fuel in the cylinder (14') corresponding to a combustion limit increases as the speed of combustion of the fuel in the cylinder (14') increases.
