Definitions

  • the invention relates to a cooling system for an internal combustion engine, in particular a motor vehicle.
  • This can be both a gasoline engine and a diesel engine.
  • the object of the invention is to improve a cooling system of an internal combustion engine so that optimum cooling of the cylinder head is achieved.
  • This object is achieved in that the cylinder head or the cylinder heads is cooled by a cooling water circuit which runs only through the cylinder head and in which a cooling water pump is inserted.
  • a second cooling water circuit runs through the engine block and has a second pump.
  • a particularly simple construction is given when a second cooling water circuit branches off from the cooling water circuit as a bypass, which is controlled by a valve and flows through the engine block.
  • the engine block is air-cooled in particular by external cooling fins, so that only a single circuit is required.
  • a very precise control is given if at least one temperature sensor is arranged in or on the cooling water circuit (s) and or on the engine, the value (s) of which is evaluated by a control unit that controls the pump (s) and or the valve controls.
  • the fluid spaces of the cylinder head have no connections with the fluid spaces of the engine block. This ensures that water cannot escape at the connection point between the engine block and the cylinder head, so that no seal or only a simple seal is required at this point.
  • Figure 1 shows a first embodiment
  • Figure 2 shows a second embodiment
  • Figure 3 shows a third embodiment.
  • Figure 4 shows a fourth embodiment.
  • Figure 5 shows a fifth embodiment.
  • Figure 6 shows a sixth embodiment.
  • FIG. 7 shows a seventh exemplary embodiment.
  • Figure 8 shows an eighth embodiment.
  • Figure 8a shows a ninth embodiment.
  • Figure 9 shows a tenth embodiment.
  • Figure 10 shows a section of the engine with a missing cylinder head gasket and a cylinder or cylinder path immersed in the cylinder head.
  • the cylinder head 3 of an internal combustion engine 1 has a cooling water circuit A through it, with a flow AI coming from the cooler 6 and flowing to the cylinder head 3 via a pump 5. The heated water flows back to the cooler 6 via the return line A2.
  • the engine block 2 is cooled via a second cooling circuit B, which has a flow line B1, through which the cooling water flows from the cooler 6 via a second pump 4 to the engine block 2.
  • the cooling water heated by the engine block flows back to the radiator 6 via the return B2.
  • the motor pumps 4 and 5 arranged in both preliminary runs AI, B1 are controlled by a control unit (motor management) 10, the control unit receiving information about the temperature from two temperature sensors 9a and 9b in the two returns.
  • the temperature sensors can also be fastened in the forerunnings or directly to the cylinder head and / or engine block 2 and the temperatures can decrease here. There is no or only a simple seal between the cylinder head 3 and the engine block 2
  • the exemplary embodiment according to FIG. 2 differs from that of FIG. 1 in that the second cooling water circuit branches off to the engine block 2 only behind the motor pump 5 via a bypass valve 7. After the motor, both returns are merged into a single return or they are returned separately.
  • the bypass valve 7, like the one motor pump 5, is controlled by the control unit 10, which in turn receives information about the temperatures through temperature sensors 9a and 9b.
  • the embodiment of Figure 3 differs in that there is only one cooling circuit A, which only flows through the cylinder head 3.
  • the engine block 2 on the other hand, is cooled by cooling fins 2a.
  • the engine block 2 is designed as a coherent workpiece and the cylinder head 3 is also designed as a coherent workpiece, see FIGS. 1, 2 and 3. Furthermore, in accordance with FIG. 4, the engine block 2 can be designed as a crankcase with attached, separate cylinder liners Cooling fins 2b and 2a either from ferritic material or from light metal casting or from another material. According to the embodiment of Figure 5, the engine block 2 is designed as a crankcase with attached, separate cylinder liners with cooling fins 2b and 2a and with separate cylinder heads 3a either made of ferritic material or from light metal casting or from another material.
  • the cylinder head is designed as an overall head 3 or as individual heads 3a with a parallel flow of coolant 7a, i.e. each cylinder head is flowed separately with cooling water which has the same temperature, with the amount of cooling water (flow) per head alternatively is controlled via the engine management, for example thermally via a valve 7b.
  • the engine block 2 is designed as an entire block or with separate cylinder liners 2b with a parallel flow of coolant 7a, i.e. each cylinder is flowed separately with cooling water which has the same temperature, the amount of cooling water (flow) per cylinder alternatively via the engine management, for example thermally controlled via a valve 7b.
  • the cooling of the cylinder head as a total head 3 or as individual heads 3a takes place, as mentioned above, with a parallel flow of coolant 7a, that is to say, cooling water flows separately onto each cylinder head.
