ABSTRACT:
An engine system with a thermal storage device is capable of efficiently supplying heat from a thermal storage device to an internal combustion engine. The engine system equipped with the thermal storage tank supplies the hot water stored in the thermal storage tank to a cylinder head of the internal combustion engine before the starting thereof. At this time, an electronic control unit sets a target value of the temperature of the internal combustion engine at the start of the hot water supply in such a manner that the lower the temperature of the internal combustion engine, the lower the target value becomes. As a result, a variation in combustion states between cylinders can be suppressed at the starting of the internal combustion engine.
