Patent attributes
An internal combustion engine system includes a fuel tank containing ethanol, a fuel tank containing at least one of gasoline and GTL naphtha, a reforming device for reforming ethanol to obtain diethyl ether, a heat exchange device for heating a heating medium, an ethanol heater for heating ethanol, and a fuel supply controlling device for controlling a mixture ratio of the fuel. The internal combustion engine system further includes an intake air heater for heating intake air with the heating medium. The internal combustion engine system includes an adiabatic storage container for storing the heating medium during a halt of an internal combustion engine. A flow controlling device is provided for supplying the heating medium to the adiabatic storage container only when a temperature detected by a thermal detector is higher than a temperature detected by a thermal detector during an operation of the internal combustion engine.
