In fig. 12, double-action thermostatic valve 20,29 mediates.Therefore, freezing mixture can flow at main cooling circuit 18 and supplement heat rejecter loop 19 and in the third and fourth coolant lines 24,27 without barrier.Freezing mixture can flow directly into supplement heat rejecter loop 19 via the first coolant lines 22 or flow into the 4th coolant lines 27 and flow into the 3rd cooling space 8 via the 4th coolant lines 27 from supplement heat rejecter loop 19.
Situation when Figure 13 illustrates that internal-combustion engine 2 is in cold.Main cooling circuit 18 by the first double-action thermostatic valve 20 closed-whole amount of coolant is by supplement heat rejecter loop 19.In addition, first and the 4th coolant lines 22,27 closed by the second double-action thermostatic valve 29, and so there is no freezing mixture and flow through the first cooling space 5 and the 3rd cooling space 8.Freezing mixture is only at the minor loop Inner eycle by coolant lines 11, oil cooler 14, second cooling space 6, vehicle heating element 15 and supplement heat rejecter loop 19.
When the running temperature of internal-combustion engine 2 raises, the first coolant lines 22 is opened by the second double-action thermostatic valve 29, as shown in figure 14.This flows through the first cooling space 5 in cylinder head 3 by enabling freezing mixture, and freezing mixture leaves the first cooling space 5 via the first coolant lines 22, and flows back to coolant pump 12 via supplement heat rejecter loop 19.
When the temperature of internal-combustion engine 2 increases further, the supplement heat rejecter loop 19 leading to coolant pump 12 is closed by the second double-action thermostatic valve 29 between crossover sites 30 as shown in figure 15 and confluence area 16.The free part 19a that the freezing mixture leaving the first cooling space 5 by the first coolant lines 22 now flows through supplement heat rejecter loop 19 enters main cooling circuit 18 in coolant chiller 17 upstream.
Figure 16 illustrates the liquid-cooling system K be moderate under higher running temperature being in internal-combustion engine.First double-action thermostatic valve 20 now closes supplement heat rejecter loop 19 and opens main cooling circuit 18.Second double-action thermostatic valve 29 is in intermediate position, in this neutral position, first and the 4th coolant lines 22,27 open, thus allow freezing mixture to flow into the free part 19a in supplement heat rejecter loop 19 from the first coolant lines 22, and flow into the 4th coolant lines 27.Therefore, first and the 3rd cooling space 5,8 will receive freezing mixture stream.Freezing mixture via first and the 4th coolant lines 22,27 to flow into the 3rd cooling space 8 of cylinder block 4 from the first cooling space 5 of cylinder head 3, and to guide towards the main cooling circuit 18 of coolant chiller 17 upstream via the 3rd coolant lines 24 and leave cylinder block 4.
Regardless of the position of thermostatic valve 20,26,28,29, oil cooler 14, will always receive freezing mixture stream for the second cooling space 6 of cooled exhaust manifold 7 and vehicle heating element 15.
