Definitions
- the invention relates to an internal combustion engine according to the preamble of claim 1.
- DE 196 00 566 C1 is a multi-cylinder internal combustion engine known in their cylinder crankcase an oil cooler is provided for lubricating oil.
- the oil cooler is in one water box cast on the side of the cylinder crankcase, which flows through cooling water from a cooling water circuit becomes. The cooling water flows around the oil cooler and is then led into the cylinder head, where it acts as a cooling water jacket is guided along the outside of the cylinder.
- the disadvantage here is that with a cold internal combustion engine, for example when starting after a long standstill, the Lubricating oil has a high viscosity due to the low temperatures and because of its reduced fluidity is unable to move the moving components of the internal combustion engine, especially the bearings of the crankshaft and Connecting rods to lubricate sufficiently.
- Another problem with a cold engine is that fuel condensed on the cylinder walls so that the air / fuel ratio deviates from the optimal value in the combustion chamber and the pollutant concentration in the exhaust gas is increased.
- DE-OS 29 05 571 proposed the cooling water with the help of an electric Preheat radiator so that the cylinder of heated Cooling water flows around and preheated. Through this Measure should make the engine more ready to start reached and frost damage can also be avoided.
- the invention has for its object the cold start properties to improve an internal combustion engine, the necessary measures without increasing the installation space should be feasible and a subsequent conversion should be possible.
- Another advantage is that the location of the oil cooler directly on the heating element or in the heated by the Cooling water flooded water box that too Lubricating oil is heated, which improves the flow properties become.
- the lubricating oil flows more easily to the bearing points, so that better lubrication of moving components is achieved becomes.
- the heated oil cooler in turn affects this Cooling water because of the increased heat radiation area of the oil cooler, the cooling water is heated faster, so that the cylinders can also be preheated in less time.
- the heating element and the oil cooler expediently form a composite, by placing the heating element directly on the oil cooler, in particular by soldering to the bottom surface of the oil cooler is. In this way you get a coherent Component made up of heating element and oil cooler, designed to save space is and especially prefabricated in the water tank used or for maintenance work from the water tank can be removed.
- the heating element is as Heating coil formed, which creates the heat radiating surface of the heating element is enlarged and the heating process is done in less time.
- the heating element is advantageously completely within the lateral border of the bottom surface of the oil cooler, so that the dimensions of the water tank essentially unchanged can be maintained and in particular the height of the Cylinder block remains the same; this way one becomes special space-saving design achieved.
- the cylinder crankcase shown in detail in Fig. 1 2 of an internal combustion engine 1 with the cylinders 8, 9 has a laterally arranged, on the cylinder crankcase cast water box 4, in which an oil cooler 3 for Lubricating oil is arranged.
- the interior of the water box 4 lies in the flow path of a cooling water circuit, which is basically serves to cool the internal combustion engine.
- the cooling water W passes through an inlet opening 10 in the cylinder crank housing 2 according to the direction of the arrow shown in the Water box 4 and flows around the oil cooler 3.
- Cooling water W is in front of the water tank 4 during the flow through the water box and behind the water box Openings 14 in a jacket wall 13 to a cooling water jacket 11 passed between the cylinder walls 12 and the jacket wall 13 is guided vertically downwards and in the cylinders 8, 9 dissipates heat generated.
- the jacket wall 13 forms at the same time a boundary wall of the water tank 4.
- Between the cylinder walls 12 are channels 15 through which the cooling water can flow through so that the cylinders 8, 9 are completely cooled.
- the channels 15 run transversely to the longitudinal axis 16 of the cylinder crankcase 2.
- the cooling water jacket 11 extends essentially parallel to the longitudinal axis 16.
- a heating element 5 is arranged to the Preheat cooling water in a cold internal combustion engine.
- the Heating element 5 lies between the jacket wall 13 and the oil cooler 3 and is on the bottom surface facing the cylinders 8, 9 6 of the oil cooler 3 fixed, in particular soldered.
- the Oil cooler 3 and the heating element 5 form a coherent Component and can be used together in the water tank or be removed from it.
- the heating element 5 is electrically heated.
- a power line 17 is provided which runs along the side of the oil cooler 3 to a cover 18 of the water tank 4 is guided and opens into a connector 19 which on the outside of the lid 18 is held.
- Fig. 2 can be seen that the heating element 5 in the water tank 4 of the cylinder crankcase 2 is formed as a heating coil is wound on the bottom surface 6 of the oil cooler 3 runs.
- a space-saving arrangement is achieved that the heating element 5 essentially within the border 7 of the bottom surface 6 extends so that the dimensions of the Oil cooler 3 and heating element 5 existing overall arrangement in the essentially determined by the size of the oil cooler become. Only the ends of the heating coil lead over the Border 7 addition to a contact possibility to the side to create on the oil cooler 3 along the power line 17.
- the cooling water W flows approximately parallel to the longitudinal axis 16 of the cylinder crankcase through the water box 4 with the oil cooler 3, which is longer than the oil cooler of the first Embodiment is formed.
- Part of the cooling water branches off from the water tank 4 and enters through openings 14 in the jacket wall 13 in a cooling water jacket 11 between the jacket wall 13 and the cylinder walls 12 of the cylinders 8, 9.
- the heating element 5 designed as a multiple coiled heating coil that inside the border 7 of the bottom surface 6 of the oil cooler 3 lies. Due to the larger number of turns, the heating element has one larger surface area so that more heat is radiated.
