Definitions

  • the cooling effect of the internal combustion engine due to the heating medium can be improved. That is, the cooling capacity of the cooling means can be increased.
  • a first cooling water passage 41 is connected at its one end with one end of the water jacket 18 in the internal combustion engine 1, and at its other end with one end of an engine related device 43.
  • the engine related device 43 there can be exemplified a cooling water tank in which cooling water is stored, a heater core of a passenger compartment heater, etc.
  • a second cooling water passage 42 is connected at its one end with the other end of the water jacket 18 in the internal combustion engine 1, and at its other end with the other end of the engine related device 43.
  • step S101 when a negative determination is made in step S101, that is, when the compression ratio of the internal combustion engine 1 is low, the execution of this routine is once stopped, so the amount of cooling water to be pressure fed by the water pump 44 per unit time is not increased. In other words, when the compression ratio of the internal combustion engine 1 is low, the increase of the cooling capacity to cool the internal combustion engine 1 is inhibited.
  • the compression ratio can be made high when the internal combustion engine 1 is operated at a high rotational speed instead of when the internal combustion engine 1 is operated under a high load. Even in such a case, by performing the above-mentioned respective control operations, the internal combustion engine 1 is able to carry out high compression ratio operation under a much higher load while suppressing an excessive rise in the temperature of the combustion chamber 7.
