Definitions
- the invention relates to a method for operating an internal combustion engine, in particular a spark-ignited internal combustion engine, wherein at least in an engine operating range both an external and internal exhaust gas recirculation is performed.
- DE 100 65 266 A1 describes a method for operating an internal combustion engine.
- the method provides that a turbulent flow is generated in the entire load range of the internal combustion engine and the combustion air is pre-compressed outside the combustion chamber.
- JP 04-175449 A describes an internal combustion engine, which has an internal and an external exhaust gas recirculation system to reduce the pumping losses in the partial load range and to prevent the occurrence of knock events.
- an internal exhaust gas recirculation is performed in the low part load range and an external exhaust gas recirculation in the high load range.
- the internal exhaust gas recirculation is controlled by adjusting the control times by means of a phase shifter.
- the recirculation of external exhaust gas in the high load range causes an increase of the cylinder pressure and a lowering of the cylinder temperature. Increasing the cylinder pressure has an accelerating effect on the combustion, but lowering the combustion temperature counteracts this and slows down combustion. As a result, the knocking behavior and the residual gas compatibility at full load can not be significantly improved.
- the object of the invention is to avoid these disadvantages and to improve the knock behavior and the Restgasver joskeit, especially at medium to high partial load and at full load.
- this is achieved in that, in order to reduce the tendency to knock, in particular during or before a knock event, the kinetic turbulent energy in the cylinder is increased at least briefly compared with a reference operating point, preferably at high load, the residual gas content in the cylinder chamber at least during the Increasing the turbulent kinetic energy by varying the opening time of the intake valve, the closing time of the intake valve and / or the closing time of the exhaust valve set becomes.
- a reference operating point preferably at high load
- the residual gas content in the cylinder chamber at least during the Increasing the turbulent kinetic energy by varying the opening time of the intake valve, the closing time of the intake valve and / or the closing time of the exhaust valve set becomes.
- the same operating point at maximum internal residual gas recirculation rate without external residual gas recirculation can be considered as the reference operating point.
- the turbulent kinetic energy in the cylinder is increased with simultaneous increase in the recirculated exhaust gas amounts, while adjusting the timing of the recirculated external residual gas.
- the method according to the invention makes use of the fact that with increasing turbulent kinetic energy, the flame propagation speed increases, thereby increasing the residual gas compatibility of the combustion process and decreasing the tendency to auto-ignition (knocking).
- the valve lift of at least one exhaust valve and / or at least one intake valve is reduced and / or the intake closing time is retarded.
- the turbulent kinetic energy is increased by at least one combustion chamber side, injection side or channel charge movement measure, wherein the combustion chamber side preferably the turbulent kinetic energy is increased by a valve masking or by expressing a squish flow in the cylinder chamber.
- a further measure according to the invention provides that the profile of the closing edge and / or the closing ramp of at least one inlet valve is changed with respect to the reference operating point with internal residual gas, wherein the closing edge and or the closing ramp during operation with internal and external Restgasismeengung flatter than in the reference operating point with pure internal residual gas admixture is set.
- Cooling of the externally recirculated exhaust gas also has an advantageous effect on reducing the tendency to knock.
- an internal combustion engine with external and internal exhaust gas recirculation system which has at least one means for increasing the turbulent kinetic energy in the cylinder chamber.
- the means for raising the kinetic energy can be formed by a variable, preferably a fully variable valve train.
- the increase in kinetic energy is achieved by retarding the inlet closing timing relative to the reference operating point. In doing so, the completion of the energy input is delayed, creating a higher kinetic turbulent energy level during the combustion process.
- the internal residual gas quantity in the case of simple variable valve train systems, is ensured by simultaneous late adjustment of the outlet closing time.
- the injection pulse occurring in the case of direct injection into the combustion chamber increases the turbulent kinetic energy in the combustion chamber while simultaneously cooling the charge quantity in the cylinder to reduce the charge temperature.
- the turbulent kinetic energy level in the combustion chamber can thus be additionally controlled.
- the internal combustion engine has a supercharger system for increasing the inlet pressure.
- the internal combustion engine but also be a naturally aspirated engine.
- Figure 1 shows the tendency to knock as a function of the pressure-temperature coefficient.
- FIG. 2 shows the tendency to knock as a function of the kinetic turbulent energy
- Fig. 4 is a valve lift crank angle diagram
- Fig. 5 is a turbulent kinetic energy-crank angle diagram.
- the knocking tendency K depends on the cylinder pressure p, the cylinder temperature T and the turbulent kinetic energy E kin in the cylinder.
- the tendency to knock K increases approximately proportionally with the product p * T of the cylinder pressure p and the cylinder temperature T and decreases with increasing turbulent kinetic energy E kin . With Kl the knock limit is indicated.
- BDC and TDC denote the lower and upper dead center of the piston in FIGS. 4 and 5, respectively.
- the aim is to achieve a reduction in knock tendency K with a high p * T coefficient in the cylinder. High exhaust gas recirculation rates at high load are to be guaranteed.
- the high residual gas compatibility is achieved by raising the turbulent kinetic energy E ki ⁇ , see Fig. 5.
- the external exhaust gas recirculation amount can be increased and the internal exhaust recirculation amount can be kept approximately the same.
- the increase of the turbulent kinetic energy E kln takes place by at least one charge movement measure, for example the reduction of the intake valve stroke, by means of a fully variable valve drive device or the retardation of the intake closing time. This effect can be enhanced by the direct injection of fuel into the combustion chamber. Where this effect can be increased again by multiple injection, see FIG. 4 and FIG. 5.
- the inlet closing Ic is retarded and adjusted or via a throttle valve.
- O indicates the outlet and, with I, the inlet valve lift curve in a reference operating point assigned, for example, to the high partial load.
- the exhaust valve lift O and O ⁇ examples, in combination with the intake valve lift functions F and F, show possible operating settings with increased turbulent kinetic energy as shown in FIG.
- the delayed inlet closure Tc and I "c causes a high level of turbulence to be delayed late into the combustion area, which has an advantageous effect on the combustion speed (FIG.
- channel-side measures are, for example, tumble and swirl channels, and swirl and / or tumble control devices in the inlet or outlet channel.
- the internal combustion engine has a supercharger system, for example a turbocharger, compressor, or the like.
- a supercharger system for example a turbocharger, compressor, or the like.
- the inventive method is particularly suitable for gasoline engine, regardless of clocking and / or Zylinderabschaltriosn.
- the knock limit can be shifted in the direction of early ignition times, so that the internal combustion engine can be operated in the region of optimum efficiency or close to this range in the full load and in the high partial load, resulting in significant advantages for consumption and emissions.
- the inventive method is independent of the injection system, the ignition system, the supercharging system, the air / fuel strategy and can be used in combination with various exhaust aftertreatment systems. While the method is best suited to fully variable valve train systems, it is also advantageous to employ the method with partially variable valve train systems.
