An engine system that includes an internal combustion engine and a heat accumulating device also includes a heat accumulating means (10) for accumulating heat by storing a heated cooling medium, heat supplying means (11,12,22,C1,C2) for supplying the cooling medium accumulated in the heat accumulating means (10) to the internal combustion engine (1), and cooling medium temperature measuring means (28,29) for measuring the temperature of the cooling medium, and failure determining means (22) for determining a failure of the heat accumulating devices (10,11,12,22,C1,C2,32) based upon a variation of a value measured by the cooling medium temperature measuring means (28,29) when the heat is being supplied by the heat supplying means (11,12,22,C1,C2). <IMAGE> |
