Definitions
- the invention relates to an internal combustion engine with electrohydraulic valve control for variable-stroke driving of a gas exchange valve subjected to spring force in the closing direction and to a method for operating the internal combustion engine.
- This comprises a camshaft and a hydraulic system arranged in the drive sense between the camshaft and the gas exchange valve, which is connected to a hydraulic fluid supply of the internal combustion engine and has the following:
- a pressure chamber of variable volume bounded by the first hydraulic piston and the second hydraulic piston and a control channel connecting the pressure chamber to a pressure relief chamber
- the internal combustion engine further comprises an electronic drive means for controlling the hydraulic valve as a function of operating parameters of the internal combustion engine.
- the operating behavior of electrohydraulic valve trains in a significant amount depends on the properties of the hydraulic fluid and, in particular, on its instantaneous and mainly temperature-induced viscosity state.
- a major cause of this dependency lies in the so-called hydraulic valve brake, which is part of the hydraulic system and replaces the valve closing ramp on the cam provided by conventional mechanical valve trains.
- the hydraulic valve brake is known to have the task of forming a decoupled from the cam lift stroke of the gas exchange valve so that the closing gas exchange valve always reaches the valve seat with mechanically and acoustically acceptable Aufsetz effet.
- the hydraulic valve brake is to be designed so that the change in charge of the internal combustion engine affecting target-actual deviations of the gas exchange valve closing timing are minimal.
- Hydraulic valve brakes are usually designed such that the hydraulic fluid displaced by the gas exchange valve-side second hydraulic piston has to pass a throttle point shortly before the gas exchange valve closes, the hydraulic resistance of which suppresses the gas exchange valve. generated hubs to the predetermined Aufsetz Anlagen.
- the viscosity-temperature response of the hydraulic fluid limits the functionality of the hydraulic valve brake to a temperature window in such a way that the closing time of the gas exchange valve below a limit temperature fluctuates and / or decelerated unduly.
- the gas exchange valve does not reach the valve seat and remains - in terms of the charge cycle and combustion process of the internal combustion engine - in an inadmissible way between two revolutions of the camshaft open.
- the electronic activation means is configured to control the hydraulic valve as a function of the operating hydraulic fluid temperature or viscosity and / or the operating pressure in the hydraulic fluid supply such that during one engine operating phase the one or immediately successive revolutions the camshaft comprises, only a predetermined partial volume of the pressure chamber is filled with hydraulic fluid and the hydraulic valve is at least during each entire elevation phase of the cam in the closed position.
- the defined presetting of the partial volume of hydraulic medium located in the pressure chamber is effected by a targeted loss of stroke of the hydraulic linkage during one or more revolutions of the camshaft before the engine operating phase and causes during the engine operating phase that the gas exchange valve opens later with respect to the cam lobe and closes earlier with correspondingly reduced lift height.
- the hydraulic valve brake remains between two camshaft revolutions for a longer time interval in which the gas exchange valve can safely reach the valve seat.
- the amount of sub-volume is to be adjusted so that the gas exchange valve does not fall below a minimum lifting height and does not exceed a maximum closing time in view of a successful change of charge. This also applies to the case that the hydraulic valve is opened in the phases between the cam lobes and thus allows a refilling of the pressure chamber with hydraulic fluid from the pressure relief chamber.
- the invention particularly promotes a successful start and initial warm-up phase of the cold internal combustion engine at very low ambient temperatures (typically at -30 ° C ambient and engine temperature to ensure a successful startup), especially under such conditions, the pressure build-up in the hydraulic fluid supply of the internal combustion engine is particularly delayed.
- insufficient pressure in the hydraulic fluid supply of the internal combustion engine can prevent a complete refilling of the pressure chamber to the extent that a controlled modification or reduction of Gas monventilhubs by cyclically true Ab Kunststoffn hydraulic fluid from the pressure chamber is not possible during the cam lobe.
- the invention also allows for cold, i. combinkosem hydraulic means with respect to the cam lift later inlet opening. As explained above, this is not possible with conventional actuation of the hydraulic valve, since the hydraulic valve does not close or does not close sufficiently quickly against highly viscous hydraulic fluid flow in the control passage.
- the invention is not limited only to its application with cold hydraulic means, but can also be used at other operating temperatures of the internal combustion engine.
- the purposes of the invention can be dispensed with a cycle-faithful refilling of the pressure chamber between the cam lobe phases, if the refilling only serves to compensate for unavoidable gap leakage from the pressure chamber and the leaks in the case of very high hydraulic fluid viscosity are negligible.
- the hydraulic valve tils be provided in such a way that the hydraulic valve remains closed not only during the engaged cam lobe phase, but during the entire engine operating phase.
- the number of revolutions of the camshaft during the engine operating phase in dependence on the determined at the time of starting the engine hydraulic fluid temperature is predetermined by the electronic drive means.
- Parameter for this predetermined number of revolutions is essentially the temperature of the hydraulic fluid during the starting process, wherein the parameter-dependent number of revolutions can be determined by test bench tests and stored in a characteristic field of the electronic control means as a control variable.
- the predetermined duration of the engine operating phase it can also be provided to set this duration as a function of current operating parameters, in particular the hydraulic fluid temperature.
- said engine operating phase may be passed once or, if necessary, several times consecutively.
- the electronic control means should be configured to control the hydraulic valve such that during one of the engine operating phases following another engine operating phase comprising immediately consecutive revolutions of the camshaft Pressure chamber is at least almost completely refilled with hydraulic fluid before each survey phase of the cam.
- the object on which the invention is based is achieved on the procedural side by the fact that the electronic control device is configured to control the hydraulic valve as a function of the operating hydraulic fluid temperature or viscosity and / or the operating pressure in the hydraulic fluid supply, wherein the following method steps are provided, which follow one another in time: Opening the hydraulic valve at a time within the elevation phase of the cam and closing the hydraulic valve at a time such that only a predetermined partial volume of the pressure chamber is filled with hydraulic fluid, and
- Figure 1 is a temporal sequence of elevations of the cam and the gas exchange valve with associated current curves on the hydraulic valve
- FIG. 2 shows a time sequence corresponding to FIG. 1, wherein the hydraulic valve is in the closed position during the entire machine operating phase;
- Figure 4 is a schematic diagram of the electro-hydraulic valve control.
- the starting point of the description is the basic representation of a known electrohydraulic valve control 1 shown in FIG.
- the valve control 1 is used for variable-stroke driving of a gas exchange valve 3 of an internal combustion engine which is subjected to a force in the closing direction by a valve spring 2.
- machine 4 and comprises as essential components a cam 5 of a camshaft 6, a cam 5 here by means of a tappet 7 driven first hydraulic piston 8, a gas exchange valve 3 in the opening direction driving second hydraulic piston 9, one between the first hydraulic piston 8 and the second hydraulic piston 9 extending pressure chamber 10 with variable volume and a pressure relief space 1 1, which is connected to the pressure chamber 10 via a control channel 12 and a spring-loaded pressure accumulator 13 includes.
- the arranged in the drive sense between the camshaft 6 and the gas exchange valve 3 hydraulic system is connected to a hydraulic fluid supply 14 of the internal combustion engine, here the lubricant circuit.
- an electrically controlled hydraulic valve 15 is arranged in the design of a 2/2-way switching valve, which allows in its de-energized open position a hydraulic fluid flow through the control channel 12 and locks in its energized closed position.
- the electrical actuation of the hydraulic valve 15 as a function of operating parameters of the internal combustion engine 4 takes place via an electronic control means 16 as an integrated component of the engine control unit.
- valve control 1 The known manner of operation of the valve control 1 can be summarized in that the hydraulic means located in the pressure chamber 10 acts as a hydraulic linkage, the elevation predetermined by the cam 5 being transferred to the gas exchange valve 3 when the hydraulic valve 15 is closed and partially open when the hydraulic valve 15 is open or is completely diverted into the pressure relief chamber 1 1.
- the hydraulic decoupling of the cam lobe and the Gas monventilhubs requires a hydraulic valve brake 17, which throttles back from the second hydraulic piston 9 hydraulic fluid and so the closing gas exchange valve 3 decelerates to a mechanically and acoustically acceptable Aufsetz economically the valve seat 18.
- FIG. 1 During the first cam elevation 20, the energized hydraulic valve 15 is de-energized, so that when the control channel 12 is open, a part of the hydraulic medium in the pressure chamber 10 is displaced into the pressure relief chamber 11 and accordingly the cam elevation 20 is only partially displaced to the gas exchange valve 3 is transmitted.
- the times at which the energization 21 of the hydraulic valve 15 is turned off and then turned back on, and the corresponding time interval in which the hydraulic valve 15 is opened and allows refilling of the pressure chamber 10, are such that at the beginning of the second cam lobe only one predetermined partial volume of the pressure chamber 10 is filled with hydraulic fluid.
- the duration of the engine operating phase includes the revolutions 2 to n of the camshaft 6.
- the control of the hydraulic valve 15 takes place in such a way that on the one hand, the hydraulic valve 15 is energized during each entire cam lift phase 20 and thus remains closed throughout.
- the time intervals between the cam elevations 20, in which the hydraulic valve 15 is not energized and consequently open are dimensioned such that, despite possible refilling of the pressure chamber 10, only a partial volume with a predetermined maximum amount of hydraulic fluid is contained therein.
- the respective subsequent gas exchange valve lift 19 moves in the predetermined Benen limits the minimum required lifting height h-min and the maximum allowable closing time a-max, as shown enlarged in Figure 3.
- the predetermined by the electronic drive means 16 number of revolutions of the camshaft 6 during the engine operating phase is dependent on the temperature of the hydraulic fluid during the starting process of the internal combustion engine 4. In the case of the examined by the applicant test rig hardware were at a hydraulic fluid temperature of -20 ° C 40 revolutions and from - 30 ° C determined 120 rotations as optimal.
- the hydraulic valve 15 Upon completion of the initial warm-up phase of the engine 4, i. After the engine operating phase with the cam lobes 2 to n, the hydraulic valve 15 is energized between the nth and ⁇ + 1 th cam lobe 20 so that the pressure chamber 10 can be completely refilled with hydraulic fluid.
- the electronic drive means 16 is configured so that this also applies to all further revolutions of the camshaft 6 during the subsequent further engine operating phase, which starts with the ⁇ + 1 th cam lobe 20 and in which the hydraulic valve 15 is closed during the cam elevation phase 20 and is opened to produce the stroke variability on the gas exchange valve 3 in a known manner.
- FIG. 2 shows the essential difference with respect to the sequence according to FIG. 1 in the control of the hydraulic valve 15 during the engine operating phase with revolutions 2 to n of the camshaft 6.
- the possibility of a cyclically correct partial refilling of the pressure chamber 10 between the cam lobe phases 20 dispensed by the hydraulic valve 15 is energized during the entire engine operating phase (current waveform 21 at revolutions 2 to n of the camshaft 6) and thus permanently closed.
- This is useful when refilling the pressure chamber 10 merely serves to compensate for unavoidable gap leakage from the pressure chamber 10 and the leaks in the case of very high hydraulic fluid viscosity are negligibly small.
