Definitions
- the invention relates to a device for cooling an internal combustion engine, preferably a four-cylinder in-line engine, according to the preamble of the main claim.
- a generic device is already known from EP 0 038 556.
- a cylinder head and a cylinder block accommodated in the internal combustion engine each have a cooling jacket region designed as a cooler pocket, the cooler pockets arranged separately from one another having coolant connections on the upstream and downstream sides for coupling to the cooling circuit, so that the cylinder head and the cylinder block of the internal combustion engine are separate from one another can be supplied with coolant, so that a separate thermal control of the cylinder head and the cylinder block is possible.
- a cooling jacket region designed as a cooler pocket
- the cooler pockets arranged separately from one another having coolant connections on the upstream and downstream sides for coupling to the cooling circuit, so that the cylinder head and the cylinder block of the internal combustion engine are separate from one another can be supplied with coolant, so that a separate thermal control of the cylinder head and the cylinder block is possible.
- the device according to the invention with the characterizing features of the main claim has the advantage that the geometric arrangement of the inflow and outflow and their flow direction relative to the arrangement of the cylinders of each individual cylinder is in direct flow contact of a flow path assigned to it and thus the number of flow paths the number of cylinders is dependent, so that a targeted and selective cooling of the individual cylinders or combustion chambers depending on the current
- Engine operating state is feasible. This makes it possible to set an approximately uniform temperature distribution of the individual cylinders in all operating states, which has a wear-reducing effect with respect to the corresponding components of the internal combustion engine. Due to the resulting low temperature variance, the tendency to knock or the nitrogen oxide emission can be reduced, for example, under full load operation.

- each cylinder 15, 15 ' , 15 " , 15 '" each have a pair of coolant connections 21, 21 ' , 22, 22 ' , 23, 23 ' , 24, 24 ' , the flow direction of which points transversely to the longitudinal direction of the crankshaft and to the respectively assigned cylinder 15, 15 ' , 15 " , 15 '” .
- the inflow and outflow flows 17 - 20, 17 ' - 20 ' , 21 - 24, 21 ' - 24 ' each have suitable metering bores with flow directions running transversely to the longitudinal direction of the crankshaft, by means of a coolant supply which can be tuned via the metering bores to each cylinder 15, 15 ' , 15 " , 15 '" and which is thereby controllable
- FIG. 3 shows the device 10 according to the invention with the associated cooling circuit.
- the coolant connections 17 - 20 assigned to the cylinder block 11 "and arranged in the transverse direction are connected to a first outlet of a mixing valve 27, while its second outlet is connected on the inflow side to the longitudinally arranged coolant connection 14, so that this mixing valve 27 adjusts the mixing ratio between serves the coolant connection 14 arranged in the longitudinal direction and the coolant connections 17 - 19 arranged in the transverse direction.
- those on the inflow side which are assigned to the cylinder head 11 ' and are arranged in the transverse direction
- Coolant connections 21-24 are connected to a first outlet of a further mixing valve 27 ', while its second outlet is connected on the inflow side to the longitudinally arranged coolant connection 13, so that this second mixing valve 27 ' adjusts the mixing ratio between the longitudinally arranged coolant connection 13 and the coolant connections 21 - 24 arranged in the transverse direction.
- the input of the first mixing valve 27 with a first output of a third mixing valve 28 and the input of the second mixing valve 27 ' with a second are used to set the upstream coolant mixing ratio between cylinder head 11 ' and cylinder block 11 "
- the transverse coolant connections 17 ′ - 20 ′ assigned to the cylinder block 11 ′′ are connected to a first inlet of a mixing valve 29, while its second inlet is connected on the outflow side to the coolant connection 14 ′ arranged in the longitudinal direction cylinder head associated with 11 "and in the transverse direction arranged coolant connections 21 '- 24' 'is connected, while the second input of which is arranged in the longitudinal direction of coolant telanschluß 13' to a first input of a further mixing valve 29 is downstream connected.
- Both mixing valves 29, 29 ' can be set separately from one another and serve to return the coolant heated in the internal combustion engine 11; they each have one Output on, the output of the mixing valve 29 being connected to the output of the mixing valve 29 ' ; These two outputs are connected to an input of a thermostat valve 31 which comprises feeding the output side via the mixing valves 29, 29 'of the cylinder head 1 1 "and the cylinder block 1 1' flowing heated coolant in a cooler 32nd
