- the invention relates to a method for thermoregulating a Internal combustion engine for vehicles according to the features of the preamble of claim 1.
- the thermal management of an internal combustion engine and a vehicle i.e. the cooling and heating of units and equipment an optimal operating temperature, is for efficiency and thus of crucial importance for the vehicle system, in particular in terms of economy, function, Lifespan and comfort. It is therefore desirable that the Devices and units, in particular the internal combustion engine the optimal operating temperature as quickly as possible reach and, if possible, maintain it throughout operation.
- EP 0 499 071 A1 describes a cooling system for a vehicle Internal combustion engine known.
- the cooling system comprises several circuits with assigned heat exchangers.

- the heat exchanger performance or the fan speed is for everyone Cooling circuits always according to the highest demand of one of the cooling circuits aligned.
- DE 37 38 412 A1 describes a method for heat regulation an internal combustion engine known in which the delivery rate of electric pumps not only depending on the coolant temperature, but depending on at least one other Operating parameter is carried out.
- receives an electronic Switching device as input signals the operating temperature of the internal combustion engine, the air temperature in the immediate vicinity of the Internal combustion engine that is further away from the internal combustion engine measurable ambient temperature, the temperature of Engine parts and the speed of the internal combustion engine and one Information about the driving speed of the vehicle.
- the electronic Switchgear processes the input signals Output signals and first gives an output signal to the electrical Pump off. Additional output signals may be on the valves are output and to an actuating device, the one arranged in front of a heat exchanger used as a cooler, adjustable Blind operated, and finally on heat exchangers assigned blower motors.
- EP 0 084 378 A1 describes a control device for a cooling system an internal combustion engine known in which the input variables can be evaluated by means of a microprocessor. As input variables serve the cooling water temperature, the vehicle speed and the ambient temperature.
- DE 38 10 174 A1 shows a device for regulating the coolant temperature an internal combustion engine, wherein a control device or evaluation device as input signals next to the cooling water temperature, the load and the speed of the internal combustion engine receives.
- the load of the internal combustion engine can indirectly by measuring the intake manifold vacuum of a mixture-compressing one Internal combustion engine or by measuring the position of the Control rod of an injection pump of an air-compressing internal combustion engine be determined.
- DE 41 09 498 describes a method for regulating the Temperature of an internal combustion engine is known, in which a control device the following operating parameters as input signals processed: temperature of the internal combustion engine, intake temperature, Engine speed, vehicle speed, load of Internal combustion engine, operating condition of the air conditioning, heating of the motor vehicle, the time, the diagnostic information, an output signal a knock control device and the temperature of the Cooling water.

Under Using a microprocessor will improve the functionality of the Cooling system monitored by the course of a temperature signal is evaluated and detected temperature changes per unit of time be compared with plausible values. The evaluation serves not to control the cooling system, but only to control it Monitoring and to reliably and reliably detect malfunctions to be able to.
- the cylinder head one is suitable as a critical component for this Internal combustion engine, namely the area between exhaust valves, the so-called dock zone. Because this area is exposed to the hot exhaust gases is, it is special due to high temperatures and frequent Temperature changes at risk. Because of its small mass and Due to its position, it reacts very much to changes in heat load quickly, so that its temperature for the heat accumulation in the internal combustion engine is very characteristic.
- the optimal operating temperatures in the starting phase reach an internal combustion engine for vehicles particularly quickly, if with increasing temperature or increasing heat the pumps put the pumps into operation and be regulated, then the thermostats, then the blind and finally the fan.
- the drawing shows the structure of a cooling system in a schematic manner to carry out the method according to the invention.
- Temperature sensors 4 and 6 record the Cooling water temperature at cooling water inlet 2 or at the cooling water outlet 3. Furthermore, the internal combustion engine 1 has in the area between Exhaust valves, in the so-called “web zone", a temperature sensor 5.
- the temperature sensors 4, 5 and 6 conduct the Temperature signals via signal lines 8 to an evaluation device 7, e.g. engine electronics, which also include performance characteristics of the Internal combustion engine 1 detects that specific to the heat are.
- the evaluation device 7 converts the input variables and characteristic values to manipulated variables. Via signal lines 9 with dashed lines corresponding control signals are shown electrically controllable devices directed to cooling or To promote heating agents, especially cooling water, cooling air and oil and regulate their volume flows.
- One of these facilities a fan 11, which is driven by a controllable electric motor 12 electrically driven and controllable water pumps 22 and 23, an electric thermostat 28 and an electrically driven one Venetian blind 24.
- the fan 11 promotes cooling air through a water cooler 13, wherein the cooling air throughput through the water cooler 13 on the one hand the speed of the fan 11 is determined, and on the other hand if the fan 11 is switched off by the position of the blind 24.
- the water pump 22 which serves as the main pump, conveys the cooling water through the water cooler 13 and the internal combustion engine 1 and through an oil cooler 14 with an oil inlet port 15 and a Oil outlet port 16, through an exhaust gas cooler 17 with an exhaust gas inlet port 18 and an exhaust outlet 19 and through a Interior heating 20.
- the direction of flow of the cooling water is with small arrows along the cooling water lines 10 indicated.
- the Cooling water system is via a compensating line 27 and a vent line 26 connected to an expansion tank 25.
- the water pumps 22 and the fan 11 is switched off and the thermostat 28 and the blind 24 closed. With increasing temperature, the Water pump 22 started up and according to the heat regulated. Thereafter, regulation of the thermostat 28 begins. Finally, the blind 24 is opened and the fan 11 starts with the scheme. The temperature continues to rise, though everyone Facilities set to maximum values or because individual Components have failed, the performance of the Internal combustion engine reduced accordingly.
