Definitions
- the invention relates to an air-cooled internal combustion engine with at least one hydrodynamic brake (retarder), the heat generated is recooled in a cooler, and with exhaust air flaps in the cooling air duct of the internal combustion engine.
- hydrodynamic brake retarder
- Such an internal combustion engine is known from DE-PS 12 30 615.
- the retarder oil cooler is arranged in series with the cylinders on the clutch side of the internal combustion engine and is closed by exhaust flaps in normal engine operation. These exhaust air flaps are then opened in braking mode and the cooling air can flow through the retarder oil cooler as desired.
- the hood pressure drops through the opening of the exhaust air flaps, so that the air throughput through the retarder cooler is relatively low and the cooler must therefore be made relatively large in order to dissipate the amount of heat generated.
- the space for such a large retarder oil cooler is practically not available in today's confined installation conditions in motor vehicles.
- the object of the present invention is therefore to provide an air-cooled internal combustion engine with at least one hydrodynamic brake of the type mentioned at the beginning Art to improve such that the cooling performance of the retarder oil cooler is improved without increasing its construction.
- the cooler is arranged in front of the cooling air blower of the internal combustion engine and that the exhaust air flaps are provided in the cooling air cover of the internal combustion engine in such a way that they are opened in the retarder mode.
- This arrangement offers the advantage that a substantially increased cooling air flow through the cooler and through the blower is achieved by opening the exhaust air flaps in the retarder mode and that at the same time the cooling air flow through the engine components is greatly reduced.
- This has the further advantage that the undesired cooling of the engine parts is practically prevented in retarder operation.
- the cooling air volume with open exhaust air flaps in contrast to closed exhaust air flaps, can be almost doubled without having to make changes to the blower, so that the retarder oil cooler has a relatively small overall volume.
- cooler it is also possible to use the cooler to cool the gear oil during normal driving. Since its heat build-up is relatively low compared to that during retarder operation, the internal combustion engine is practically not impaired thereby.
- the exhaust air flaps can be controlled via a linkage and a hydraulic or pneumatic actuator.
- the actuator can be operated directly by hand or depending on the retarder oil temperature or together with switching on the retarder mode.
- FIG. 1a shows a schematic side view of an air-cooled internal combustion engine 1. As the top view in FIG. 1b shows, it is designed as a V-type internal combustion engine and has two rows of 6 cylinders each.
- the impeller 2 is arranged on the front end face and is driven by a speed-controllable drive (not shown).
- the retarder cooler 3 In front of the blower 2 is the retarder cooler 3, which is connected to the blower via air guiding surfaces.
- the V-space of the internal combustion engine, into which the fan 2 conveys the cooling air, is closed at the top by a large number of exhaust air flaps 4.
- These exhaust flaps are arranged like a shutter and can be rotated about their longitudinal axis so that they release a passage cross section.
- the blower map in FIG. 2 has, for example, two operating points I and II.
- the operating point I is reached at the rated engine speed and full load with the exhaust flaps 4 closed.
- the total static pressure loss of the radiator and engine is 20 mbar, the pressure loss in the radiator being approximately 2 mbar and in the remaining internal combustion engine approximately 18 mbar.
- the operating point II which represents the retarder operation with the exhaust air flaps open and the same fan speed, is characterized by the fact that the static pressure loss in the cooling space has decreased by approx.
