- the invention relates to a dual-circuit water cooling of an internal combustion engine.
- Such internal combustion engines are z. B. from DE 196 28 762 A1 discloses, this shows a cooling circuit of an internal combustion engine with a cast cylinder block with a cooling water jacket, a cylinder head with cooling water channels, a common flange between the cylinder head and cylinder block, and with cooling water ducts within the cylinder block, as feed - Or return channels are formed, of which at least one cooling water duct opens into the flange, wherein between the cooling water jacket and at least one of the cooling water ducts a compound in the form of a cast-out of the flange surface in the cylinder block cast slot.
- the water is passed in different ways from the pump to the passages to be cooled in the crankcase.
- an internal combustion engine in particular with a two-circuit water cooling, comprising a crankcase having a water jacket and at least one arranged in front of the crankcase and communicating with this, coolant receiving inlet and / or outlet rail, at least one coolant cylinder head and at least one emptying and / or inlet rail, which communicates with the cylinder head and communicates with the coolant.
- a method for operating an internal combustion engine characterized in that a device according to one or more of the preceding claims is used.
- the cooling circuit has a low pressure drop and a uniform distribution of the coolant. This saves pump power, generates less cylinder distortion and provides effective cooling.
- Figure 1 a standard single-circuit water cycle
- FIG 4 “Common-RaN” water jacket, two-circuit water circuit with oil cooler in the intake rail
- Figure 5 the water flow in the crankcase with flow vanes on the inlet side
- FIG. 6 the water flow in the crankcase with flow vanes on the inlet and outlet side
- Figure 8 the firing floor.
- FIG. 1 by way of example, a standard single-circuit water circuit is shown, with internal combustion engine 1 having a crankcase 2 and a cylinder head 3 mounted thereon.
- the cooling circuit of the internal combustion engine 1 has a coolant pump 4, after which in the flow direction of the coolant, a motor oil cooler (MAE) 5 is arranged.
- MAE motor oil cooler
- the coolant flow branches into the exhaust gas recirculation (EGR) s cooler 6 and the crankcase 2. After the coolant has flowed through the crankcase 2, it reaches the cylinder head 3.
- EGR exhaust gas recirculation
- FIG. 2 shows, by way of example, a "common rail" water jacket single-circuit water cycle.
- An advantageous cooling view is a water flow flowing essentially in the transverse direction in the crankcase 2 and in the cylinder head 3.
- the water from the pump can flow in at low-loss, from which the water flows to the individual cylinders, and from this rail, water can be used for other coolers For example, EGR coolers and engine oil coolers can be removed as needed Cross sections are adjusted.
- the rail should be conical in the best case to allow uniform water velocities and low-loss water withdrawals.
- the water flows on leaving the head region (ideally on the side of the outlet channels, to allow maximum cooling) in a second volume, the outlet rail, which should also be conically shaped according to the amounts of water. From there, the water flows in the usual way to the thermostat. For a single-circuit water cycle, this is shown schematically in FIG.
- the cooling circuit of the internal combustion engine 1 has a coolant pump 4, after which an inlet rail 9 is arranged in the flow direction of the coolant, wherein the coolant flow in the flow direction in an engine oil cooler (M ⁇ K) 5 and an exhaust gas recirculation (EGR) s cooler 6, the are arranged before or after the intake rail 9 and branched into the crankcase 2.
- EGR exhaust gas recirculation
- the coolant of the substream originating from the inlet rail 9 flows through the crankcase 2 after it has passed through the crankcase 2, reaches the cylinder head 3. After the coolant has flowed through the cylinder head 3, it flows into the outlet rail 10. This coming from outlet rail 10, 5 M ⁇ K and AGR 6 and combined coolant flow now reaches the thermostat 7, which directs the coolant flow either directly to the coolant pump 4 depending on the working position or take the detour via the radiator 8.
- FIG. 3 discloses a "common RaM” water jacket - two-circuit water circuit with “split cooling” (FIGS. 3 and 4).
- the internal combustion engine 1 which has a crankcase 2 and a cylinder head 3 mounted thereon.
- the cooling circuit of the internal combustion engine 1 has a coolant pump 4, after which an inlet rail 9 is arranged in the flow direction of the coolant, wherein the coolant flow in the flow direction in an engine oil cooler (M ⁇ K) 5 and an exhaust gas recirculation (EGR) s-cooler 6, the are arranged after the intake rail 9 and branched into the crankcase 2 and the cylinder head 3.
- M ⁇ K engine oil cooler
- EGR exhaust gas recirculation
- the coolant of the partial flow originating from the inlet rail 9 flows through the crankcase 2 and the cylinder head 3 on the one hand. After the coolant has flowed through the crankcase 2, it reaches the outlet rail 11. After the other partial flow of the inlet rail coolant the cylinder head 3 flows through, it flows into the outlet Rail 10 of the cylinder head. This from outlet rail 10, outlet rail 1 1, 5 M ⁇ K and AGR 6 derived and combined coolant flow now reaches the thermostat 7, which directs the coolant flow, depending on the working position, either directly to the coolant pump 4 or take the detour via the radiator 8 leaves.
- crankcase 2 and cylinder head 3 In both cases, the common-rail water jacket enables particularly effective, uniform and low-pressure cross-flow cooling of crankcase 2 and cylinder head 3. The details would have to be designed using CFD calculations.
- the cooling circuit of the internal combustion engine 1 has a coolant pump 4, after which an inlet rail 9 is arranged in the flow direction of the coolant, wherein the coolant flow in the flow direction in an engine oil cooler (MAK) 5 and an exhaust gas recirculation (EGR) s-cooler 6, the are arranged after the intake rail 9 and branched into the crankcase 2 and the cylinder head 3.
- MAK engine oil cooler
- EGR exhaust gas recirculation
- the coolant flow merges with the coolant partial stream emerging from the outlet rail 10 of the cylinder head and the outlet rail 11 of the crankcase.
- the exiting from the outlet rail 11 of the crankcase partial flow of the coolant flows through a controlled flap 12, which communicates with the engine control, not shown.
- the controlled flap 12 is capable of quantitatively controlling the refrigerant flow originating from the outlet rail 1 1 of the crankcase.
- the flow range of the controlled damper is between the boundary conditions "full throughput". flow "and" completely closed ".
- the coolant of the partial flow originating from the inlet rail 9 flows through the crankcase 2 and the cylinder head 3 on the one hand. After the coolant has flowed through the crankcase 2, it reaches the outlet rail 11. After the other partial flow of the inlet rail coolant heats the cylinder head 3, it flows into the exhaust rail 10 of the cylinder head. This coming from outlet rail 10, outlet rail 11, 5 M ⁇ K and AGR 6 and combined coolant flow now reaches the thermostat 7, which directs the coolant flow either directly to the coolant pump 4 depending on the working position or take the detour via the radiator 8.
- FIG. 5 shows by way of example the flow of water in the crankcase 2 of the six-cylinder internal combustion engine 1 with flow guide vanes 14 formed as claws on the inlet side.
- the fluid glaze paddles can be seen as a replacement or supplement to the conical shape of the rail.
- Fig. 6 they are exemplified not conical.
- the internal combustion engine 1 has claw-like flow guide vanes 14 in the water jacket guide.
- the claw-like water jacket guide has an individual depth x (1-6) between the end tips of the flow vanes 14.
