Definitions
- the invention relates to an internal combustion engine with a coolant circuit according to the preamble of claim 1.
- a liquid-cooled internal combustion engine with a two-circuit cooling system in which a liquid-cooled crankcase and a separate, liquid-cooled cylinder head are connected in a coolant-valve-controlled manner in a coolant-conducting manner through openings in an interposed cylinder head gasket.
- One or more of the valves used to control the coolant are integrated as bimetallic valves in a cylinder head gasket.
- the internal combustion engine according to the invention which is assigned a coolant circuit with a first cooling line for a crankcase and a second cooling line for a cylinder head, which has at least one intake valve and at least one exhaust valve per cylinder, is characterized by an additional cooling channel which is located in the cylinder head the vicinity of the valves is provided.
- the additional cooling channel is also known as a web cooling hole. This additional cooling duct is connected to the second cooling line, which is assigned to the cylinder head.
- the internal combustion engine according to the invention can be used in particular as a traction drive in a means of transport, for example a motor vehicle.
- the first cooling line for the crankcase is assigned an actuator which serves to control or regulate a coolant inflow as a function of a temperature, in particular a coolant temperature.
- a temperature in particular a coolant temperature.
- An internal combustion engine temperature for example an engine oil temperature or a cylinder head temperature
- the control of the actuator and the evaluation of the temperature values can take place via a control unit assigned to the internal combustion engine or a motor vehicle with a corresponding internal combustion engine and / or via an additional control unit.
- an active and / or a passive switching element for example a thermostat, can be used as the actuator.
- At least two exhaust valves are provided per cylinder and the additional cooling duct is arranged in the cylinder head between these two exhaust valves.
- FIG. 1 is a schematic representation of an internal combustion engine according to the invention with a coolant circuit
- Fig. 2 is a vertical section of a cylinder head with an additional cooling channel
- Fig. 3 shows a horizontal section of a cylinder head with an additional cooling channel. Functionally identical components are provided with the same reference symbols in the drawings.
- FIG. 1 shows an internal combustion engine 1 according to the invention with a coolant circuit 2.
- a pump 7 is arranged in the coolant circuit 2 and the coolant flow generated by the coolant pump 7 is divided into a first cooling line 6 for a crankcase 4 and a second cooling line 5 for a cylinder head 3.
- the cooling lines 5 and 6 can also be referred to as collecting channels. The division preferably takes place on the crankcase 4.
- the cooling lines 5 and 6 can be integrated in the crankcase 4 or can be designed as separate components or as a separate component.
- the second cooling line 5 is preferably assigned at least one transition (not shown) to the cylinder head 3, via which the second cooling line 5 is connected to an additional cooling channel (not shown) in the cylinder head 3.
- the first cooling line 6 is connected to the crankcase 4 or to a water jacket of the crankcase 4.
- an actuator 8 is provided, which is assigned to the first cooling line 6.
- the coolant supply to the first cooling line 6 is controlled or regulated as a function of a coolant temperature via the actuator 8.
- the actuator 8 is preferably a passive and / or an active switching element, for example a thermostat.
- a control and / or evaluation unit (not shown) is assigned to the actuator 8 and is used in particular to evaluate a measured and / or estimated temperature signal and to actuate the actuator 8.
- the second cooling line 5 and thus the additional cooling channel, not shown, in the cylinder head 3 are therefore constantly supplied with coolant, while the cooling of the crankcase 4 by the first cooling line 6 can preferably be switched on if necessary by means of appropriate actuation / position of the actuator 8.
- the coolant flow in the second cooling line 5 thus forms a main coolant flow.
- the first cooling line 6 is also assigned at least one transition, not shown, to the cylinder head 3, via which the cylinder head 3 can also be supplied with coolant.
- the coolant flow of the first cooling line 6 and the coolant flow of the second cooling line 5 can then be combined in the cylinder head 3.
- the coolant flows or the respective directions of the coolant flows are indicated in FIG. 1 by straight arrows.
- FIG. 2 shows a vertical section of a cylinder head 3 of an internal combustion engine according to the invention with an additional cooling duct 9.
- FIG. 3 shows a corresponding horizontal section of a cylinder head 3 with an additional cooling duct 9.
- Flow directions of the coolant are indicated by straight arrows in FIG. 3.
- the coolant can pass from the second cooling line 5 (see FIG. 1) into the cooling channel 9 via at least one transition or transition 10 from the crankcase into the additional cooling channel or the web cooling bore 9.
- the cylinder head 3 has, for example, two intake valves and intake ducts 12 assigned to them and two exhaust valves and exhaust ducts 11 assigned to them for the exhaust gas.
- the cooling duct 9 is preferably arranged between the outlet valves or the corresponding outlet ducts 11, the coolant flow preferably flowing in the direction of a combustion chamber center (not shown) or in the direction of an injector / an injection nozzle or a shaft 13 associated therewith.
- a spark plug (not shown) can also be provided for petrol engine operation.
- the area between the outlet channels 11, the injector shaft 13 and a cylinder base 15 is advantageously cooled or supplied with coolant by the additional cooling channel 9.
- transitions 14 from the crankcase into the cylinder head 3 can be provided, with which the remaining cylinder head 3 can be supplied with coolant.
- the flow direction is preferably again, as described above for the additional cooling duct 9, in the direction of the center of the combustion chamber.
- the coolant flows which reach the cylinder head 3 via the at least one transition 10 and the transitions 14 are summarized again in the cylinder head 3.
- a coolant transfer or coolant transfer 14 from the water jacket of the crankcase or from the first cooling line 6 (see FIG. 1) for the crankcase preferably takes place via openings or openings of a defined cross-sectional area of a cylinder head gasket, not shown.
- a transition 10 from the crankcase or from the second cooling line 5 (see FIG. 1) for the cylinder head 3 is preferably also realized as an opening or opening of a defined cross-sectional area of a cylinder head gasket, not shown.
