In the present invention, the number of water-temperature sensors that detect the temperature of cooling water (12) that has passed through an engine (1) is increased to two (18, 19), and a control device (20) is provided that verifies that the detected temperature from each of said water-temperature sensors (18, 19) is within normal limits and then uses one of said detected temperatures as the temperature of the cooling water (12). Said control device (20) is configured such that if the detected temperature from one of the water-temperature sensors (18, 19) is not within normal limits, the remaining detected temperature is used as the temperature of the cooling water (12), said remaining detected temperature being within normal limits. |
