PURPOSE:To reduce the warming operation time by installing a controller which compares the data from a cooling-water temperature detector and a revolution- number detector with the values set by a setting device and increasing automatically the revolution speed when the cooling-water temperature is low. CONSTITUTION:When the cooling-water temperature is below, a set value during low-speed operation, e.g., idle operation, the data from a cooling-water temperature detector 1 and a revolution-number detector 2 are compared, in a controller 4, with the value set 6y a setting device 3. Then, the signal from the controller 4 is amplified in an amplifier 5 and transmitted to an actuator 6, and the engine revolutin speed is increased. Thus, the cooling-water temperature is increased, so the warming operation time can be reduced. |
