Document Type and Number:
Japanese Patent JP6562028
Kind Code:
B2
Abstract:
A control device for an internal combustion engine includes a fuel tank, a high pressure fuel passage, a pressure increasing device, a switching device, a low pressure fuel passage, a temperature sensor, a fuel injector, and an electronic control unit. The electronic control unit is configured to determine that there is an abnormality in the switching device when a temperature measured by the temperature sensor when the pressure increase signal is output is not higher than a temperature measured by the temperature sensor when the pressure increase signal is not output. The electronic control unit is configured to stop fuel pressure increase by the pressure increasing device by stopping an output of the pressure increase signal regardless of the engine operation state when the electronic control unit determines that there is the abnormality in the switching device.
