Abstract
A self-ignition combustion engine has a control unit that controls the temperature of the intake air such that the operating load range of compression self-ignition combustion is expanded. In operating regions where cooling the intake air results in an intake air temperature that is too low and an inability to conduct self-ignition operation, the temperature of the intake air is raised by directing intake air that has been supercharged by a supercharger to a bypass passage so that it does not pass through an inter-cooler.
