Abstract: PROBLEM TO BE SOLVED: To prevent degradation in the fuel consumption and reduction in the flow rate in a cylinder head as the supply of cooling water to a cylinder block of a two-system cooling device is started.SOLUTION: In a two-system cooling device, an outlet side of an in-head cooling water flow passage 2a is branched. One branch forms a first branched pipe 1c connected to a radiator flow passage 5A and a heater flow passage 6A, and the other branch forms a second branch pipe 1d connected to an in-block cooling water flow passage 3a. In a condition in which the supply of cooling water to the in-block cooling water flow passage 3a is stopped, and cooling water is supplied to the in-head cooling water flow passage 2a, when starting the supply of cooling water to the in-block cooling water flow passage 3a, a situation is avoided, in which cooling water flowing in the in-head cooling water flow passage 2a is heated hot, and flows into the in-block cooling water flow passage 3a, and the temperature of a cylinder block 3 is rapidly dropped. Thus, the fuel consumption rate is improved, and the reliability of an engine E is ensured.

Abstract: PROBLEM TO BE SOLVED: To provide a cooling devic for an internal combustion engine capable of differentiating the operation timing of each thermostat while achieving the communalization of thermowax or the like of each thermostat.SOLUTION: In a two-system cooling device having first and second thermostats, the first thermostat 4 has a guide member 46 for changing the streamline of cooling water flowing in from a bypass flow passage 1f to a heat-sensing cylinder 41a. The second thermostat has the same constitution as that of the first thermostat 4, and its arrangement posture has the phase difference of 180° to the arrangement posture of the first thermostat 4. Thus, in the second thermostat, the flow of cooling water from a pump flow-out passage to a head side flow passage is not blocked by the guide member. Thus, the operation timing of the first thermostat 4 can be expedited and the operation timing of the second thermostat can be delayed.
