Abstract

A coolant circulation system includes a coolant circuit (R10) including a water jacket (36, 45), a motor-driven pump (60), an outlet liquid temperature sensor (54), and a controller (100). The controller (100) executes variation determination control for driving the motor-driven pump (60) to determine whether a variation in the temperature of the coolant in a diesel engine is equal to or less than a predetermined value based on an outlet temperature detected by the outlet liquid temperature sensor (54). The controller (100) executes circulation stop control on condition that it is determined that the variation in the temperature of the coolant is equal to or less than the predetermined value. The controller (100) changes the period during which the circulation stop control is executed in accordance with the outlet liquid temperature detected at the start of the circulation stop control.
