Definitions
- the invention relates to a cooling system for an internal combustion engine with at least one cylinder head, which is connected via at least one cylinder head sealing surface with at least one cylinder block, with at least one arranged in the cylinder head first cooling jacket, which is fluidly connected to at least one coolant inlet and at least a first coolant outlet, and at least a second cooling jacket arranged in the cylinder block, which is connected to at least one second coolant outlet, wherein the first and the second cooling jacket are connected to one another via at least one connecting flow path, preferably through an opening in a cylinder head sealing surface, and through which a liquid coolant can flow successively; and wherein the coolant flow through the second cooling jacket via at least a first valve, preferably a thermostatic valve, is controllable, which in a first valve position thedemi ttelstrom locks by the second cooling jacket and releases in at least a second valve position.
- a first valve preferably a thermostatic valve
- an internal combustion engine with a cylinder head and a cylinder block wherein the cylinder head and cylinder block each have a cooling jacket.
- the cooling jacket of the cylinder block is in fluid communication with the cooling jacket of the cylinder head, wherein the coolant enters the cooling jacket of the cylinder head and flows from the cooling jacket of the cylinder head into the cooling jacket of the cylinder block.
- EP 1 258 609 A2 discloses a similar water-cooled internal combustion engine with a cooling jacket in the cylinder head and a cooling jacket in the cylinder block, wherein in the cold state, the coolant only through the cooling jacket of the cylinder head and in the warm state in addition by the cooling jacket of the cylinder block and a cylinder block downstream Radiator is passed. The coolant from the cooling jacket of the cylinder head flows directly into the return line leading to the coolant pump.
- Both GB 2 348 485 A and EP 1 258 609 A2 have coolant inlet and coolant outlet of the cooling jacket of the cylinder head at different ends of the cylinder head, whereby the cooling jacket of the cylinder head flows through in the longitudinal direction. As a result, a relatively large cooling jacket cross section in the cylinder head is required. The necessary relatively large coolant volume results in the disadvantage of relatively long heating times of the coolant.
- EP 2 562 379 A1 describes a separate coolant circuit for an internal combustion engine, wherein a cylinder head water jacket and an engine block water jacket are provided.
- the separate coolant circuit includes a pump, a radiator, a control, an exhaust housing, and a heater, wherein coolant circulates in the separate coolant.
- the control is connected downstream of the cylinder head water jacket and has a thermostat and a separate proportional valve. Through the control, the coolant can be supplied to either a radiator or the engine block water jacket. Both the cylinder head water jacket and the cylinder block water jacket are flowed through longitudinally. This longitudinal flow, as well as a relatively large number of required external lines between cylinder head water jacket and cylinder block water jacket have an adverse effect on the volume of coolant.
- the object of the invention is to avoid these disadvantages and to improve the cooling and heating behavior.
- the first cooling jacket preferably also the second cooling jacket
- the first cooling jacket can be flowed through in a transverse direction of the internal combustion engine, preferably in the flow path between the first cooling jacket and the first coolant outlet at least one substantially extending in the longitudinal direction of the internal combustion engine collecting space and / or in the flow path between the coolant inlet and the first cooling jacket, a distribution chamber extending substantially in the longitudinal direction of the internal combustion engine is arranged.
- the transverse direction of the internal combustion engine is understood to mean a direction approximately normal to the crankshaft axis and normal to the cylinder axis.
- the second cooling jacket is activated or deactivated as needed, wherein the first cooling jacket of the cylinder head is always flowed through by the full amount of coolant.
- the collecting space for the coolant can be integrated into the cylinder block according to a first embodiment of the invention.
- the collecting space is hydraulically separated from the second cooling jacket within the cylinder block.
- the collecting space is arranged in the cylinder head, wherein preferably the collecting space between the outlet channels and the cylinder head sealing surface is arranged.
- This arrangement has the advantage that the outlet channels, and possibly also an exhaust manifold integrated in the cylinder head, can be additionally cooled by the collecting space integrated in the cylinder head.
- the collecting space may extend substantially over the entire length of the cylinder head or the cylinder block
- the first coolant outlet of the cylinder head continuously flow connected to the return line of the cooling system and the second coolant outlet of the cylinder head on the first valve is switchably connected to a return line of the cooling system.
- a mixing chamber of the first valve has a first and a second valve inlet, and a valve outlet and the first coolant outlet of the cylinder head with the first valve inlet, the second coolant outlet with the second valve inlet and the valve outlet with a return line of the cooling system is fluidly connected , wherein preferably only the flow connection between the second valve inlet and the valve outlet is switchable by the first valve.
- the return line may comprise a long return train having at least one radiator and a short return train bypassing the radiator, wherein the flow of coolant through the short or long return train may be controlled by at least one second valve, preferably a thermostatic valve. About the second valve, the coolant can be fed back either directly or via a radiator of the coolant pump.
- the first cooling jacket flows through the entire coolant flow. Downstream of the first cooling jacket, the first valve is arranged, which completely blocks the outflow of the coolant from the second cooling jacket of the cylinder block in a first position. Thus, the entire coolant is fed directly to the return line of the cooling system. If the first valve moves into the second position, a partial flow of the coolant is conducted into the second cooling jacket of the cylinder block. After flowing through the second cooling jacket, the coolant is passed via a transfer channel back into the cylinder head, where it is supplied via the first valve to the coolant system.
- the coolant pump is driven by a camshaft preferably arranged in the cylinder head.
- a particularly low coolant volume and thus very short heating times can be achieved if the coolant inlet, the first coolant outlet and the second coolant outlet are arranged in the cylinder head.

Thereafter, the coolant passes through collecting channels 18 in the likewise arranged in the cylinder head 1 collecting space 14b.
- the first valve 8 is switched to the second valve position, as shown in FIG. 14 is shown. In this position, both the flow connection between the first valve inlet 8a and the valve outlet 8c of the first valve 8, as well as the flow connection between the second valve inlet 8b and the valve outlet 8c are released. As a result, part of the coolant flows from the first cooling jacket 5 of the cylinder head 1 via the connecting flow paths 17 into the second cooling jacket 6 and from there via the riser 21 to the second coolant outlet 20 of the cylinder head 1.
- FIG. 15 shows the flow between distributor space 16 and second cooling jacket 6 or collecting space 14b for this second switching position of the cooling system 4.
- the second valve 9 also switches from a second switching temperature into the second one Valve position, which is shown in Fig. 16.
- the short return line 23 is blocked and the flow from the radiator 10 to the coolant pump 7 is released.
- the coolant leaving the first valve 8 now flows through the long return line 24 through the radiator 10 and, after passing through the second valve 9, reaches the coolant pump 7. 17 shown through flow of the first cooling jacket 5 and the second cooling jacket 6 is analogous to FIG. 14 and FIG. 15.
- the second embodiment with the arranged in the cylinder head 1 between at least one outlet channel 29 and the cylinder head sealing surface 28 of the cylinder head 1 plenum 14b has the advantage that the coolant volume of the cooling system 4 can be made very small, and on the other hand, a particularly high heat dissipation from the Exhaust ports 29 is possible, in particular, if the exhaust manifold 30 is integrated into the cylinder head 1, as shown in FIG. 18 can be seen. This in turn has a particularly advantageous effect on the heating time of the coolant during a cold start of the internal combustion engine.
