Abstract:
A controller for a direct-injection internal combustion engine in which fuel is directly injected into a combustion chamber via a fuel injection valve, and a mixture formed thereby is burned by igniting the mixture via an ignition plug, which the controller, when the internal combustion engine is started under very low temperature conditions, controls an ignition cut operation that inhibits ignition and performs fuel injection only, the controller including an engine-start control unit that, when the internal combustion engine is started under very low temperature conditions after the ignition cut operation was performed, determines whether there is fuel that can contribute to combustion in a cylinder and if there is, inhibits the ignition cut operation, or limits a number of times of the cutting off of ignition.
