Definitions
- the invention relates to a method for heat regulation of an 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 devices to an optimal operating temperature is of crucial importance for the efficiency and thus for the economy of the system "vehicle". It is therefore desirable that the devices and units, in particular the internal combustion engine of the vehicle, as far as possible quickly reach their optimal operating temperature and, if possible, maintain it throughout the entire operation.
- a cooling system for a vehicle with an internal combustion engine is known from EP 0 499 071 AI.
- the cooling system comprises several circuits with assigned heat exchangers.
- the temperatures of different cooling media are measured and processed into output signals in a central evaluation device, by means of which electrically controllable devices such as speed-controlled pumps, speed-controlled fans, electrically controllable valves and a blind arranged in the air flow path can be controlled.
- the heat exchanger output or the fan speed for all cooling circuits is always aligned to the highest demand of one of the cooling circuits.
- Central heat management ensures that little drive energy is required for pumps and fans to cool and heat the system and that the system does not remove too much heat energy. will. As a result, the required operating temperatures are quickly reached at startup.
- an electronic switching device receives as input signals the operating temperature of the internal combustion engine, the air temperature in the immediate vicinity of the internal combustion engine, the ambient temperature measurable further away from the internal combustion engine, the temperature of engine parts and the speed of the internal combustion engine, and information about the driving speed of the vehicle.
- the electronic switching device processes the input signals into output signals and first emits an output signal to the electric pump. Further output signals are optionally output to the valves and to an actuating device which actuates an adjustable blind arranged in front of a heat exchanger used as a cooler, and finally to fan motors assigned to heat exchangers.
- a control device for a cooling system of an internal combustion engine is known from EP 0 084 378 A1, in which the input variables are evaluated by means of a microprocessor.
- the cooling water temperature, vehicle speed and ambient temperature serve as input variables.
- DE 38 10 174 AI shows a device for controlling the coolant temperature of an internal combustion engine, a control device or evaluation device receiving input signals in addition to the cooling water temperature, the load and the speed of the internal combustion engine.
- the load of the internal combustion engine can be determined indirectly by measuring the intake manifold vacuum of a mixture-compressing internal combustion engine or by measuring the position of the control rod of an injection pump of an air-compressing internal combustion engine.
- a method for regulating the temperature of an internal combustion engine in which a control device processes the following operating parameters as input signals: temperature of the internal combustion engine, intake temperature, speed of the internal combustion engine, vehicle speed, load of the internal combustion engine, operating state of the air conditioning system , the heating of the motor vehicle, the time, the diagnostic information, an output signal of a knock control device and the temperature of the cooling water.
- a device for monitoring the cooling system in an internal combustion engine is known from DE 44 26 494 AI.
- the functionality of the cooling system is monitored using a microprocessor by evaluating the course of a temperature signal and comparing detected temperature changes per unit of time with plausible values. The evaluation is not used to control the cooling system, but only to monitor it and to be able to reliably and reliably identify malfunctions.
- the invention has for its object to propose a method in which quicker and more immediate intervention in the heat regulation of the internal combustion engine.
- This object is achieved with the features of claim 1.
- critical component temperatures and / or performance characteristics of the internal combustion engine are recorded for the temperatures of the coolants or heating means and taken into account in the control. Since the critical components react more directly to an increased heat build-up and their temperature changes significantly earlier before the coolant temperature reacts delayed due to heat transfer, it is possible to quickly intervene in the heat regulation. This is accelerated by the method according to the invention in that not only the temperature values as such but also the change in temperatures per unit of time is taken into account in the control. The tendency of the temperature profile gives an important indication early on whether cooling has to be more intensive or weaker.
- the cylinder head of an internal combustion engine is suitable as a critical component for this purpose, namely the area between exhaust valves, the so-called land zone. As this area is exposed to the hot exhaust gases, it is particularly at risk from high temperatures and frequent temperature changes. Because of its low mass and its location, it reacts very quickly to changes in the heat load, so that its temperature is very characteristic of the amount of heat generated in the internal combustion engine.
- the method according to the invention it is also proposed to record performance characteristics of the internal combustion engine that are specific to the heat behavior, for example expediently the amount of fuel introduced into a combustion chamber per unit of time or working cycle.
- a parameter can be obtained for the control before the actual heat generation takes place or before a critical component has reached the corresponding temperature.
- the inventive method and its refinements allow the optimum operating temperatures to be reached particularly quickly in the starting phase of an internal combustion engine for vehicles, if the devices are used to start and control the pumps, then the thermostats and then the temperature as the temperature increases Blind and finally the fan.
- the drawing shows the structure of a cooling system for carrying out the method according to the invention in a schematic manner.
- the internal combustion engine 1 denotes a water-cooled internal combustion engine of a vehicle, which has a cooling water inlet 2 and a cooling water outlet 3. Temperature sensors 4 and 6 detect the cooling water temperature at the cooling water inlet 2 and at the cooling water outlet 3. Furthermore, the internal combustion engine 1 has a temperature sensor 5 in the area between outlet valves, in the so-called ⁇ land zone "". The temperature sensors 4, 5 and 6 conduct the temperature signals via signal lines 8 to an evaluation device 7, for example engine electronics, which also records performance characteristics of the internal combustion engine 1 that are specific to the heat generation.
- the evaluation device 7 converts the input variables and characteristic values into manipulated variables.
- Corresponding control signals are sent to electrically controllable devices via signal lines 9, which are shown with dashed lines, in order to convey cooling or heating means, in particular cooling water, cooling air and oil, and to regulate their volume flows.
- These devices include 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 blind 24.
- the fan 11 conveys cooling air through a water cooler 13, the cooling air throughput through the water cooler 13 being determined, on the one hand, by the speed of the fan 11 and, on the other hand, when 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 connector 15 and an oil outlet connector 16, through an exhaust gas recooler 17 with an exhaust gas inlet connector 18 and an exhaust outlet connector 19 and through an interior heater 20.
- the direction of flow of the cooling water is indicated by small arrows along the cooling water lines 10.
- the cooling water system is connected to an expansion tank 25 via an equalization line 27 and a ventilation line 26.
- the water pump 23 which serves as an additional pump, ensures the cooling water delivery when the water pump 22 is stopped when there is little heat. Above all, it ensures the function of the interior heating 20, which can be controlled via a duo valve 21.
- the water pump 22 and the fan 11 are first switched off and the thermostat 28 and the blind 24 are closed. With increasing temperature, the water pump 22 is first put into operation and regulated according to the amount of heat. Thereafter, the regulation of the thermostat 28 begins. Finally, the blind 24 is opened and the fan 11 begins to regulate. If the temperature continues to rise even though all devices are set to maximum values or because individual components have failed, the performance of the internal combustion engine is reduced accordingly for safety.
