Definitions
- the invention relates to a method for operating an internal combustion engine with an exhaust gas recirculation system and at least one exhaust gas turbocharger, wherein exhaust gas on separate, separately controllable flow paths on the one hand the Abgastur- turbine of the exhaust gas turbocharger and on the other hand the exhaust gas recirculation system is supplied, and wherein the flow path to the exhaust gas turbine via at least a first valve and the flow path to the exhaust gas recirculation system is controlled via at least a second valve.
- WO 2008/090 273 A2 discloses an internal combustion engine with an exhaust gas turbocharger, in which an exhaust gas collector emanates a first exhaust gas line to an exhaust gas turbine for driving a compressor and a second exhaust gas line for returning exhaust gas into the intake collector.
- an exhaust gas recirculation valve is arranged, which is actuated synchronously with the rotation of the internal combustion engine.
- the exhaust gas mass flow is not continuously distributed in this way between the exhaust turbine and exhaust gas recirculation system, but clocked in time. In this way, the high-energy pressure surge when opening the exhaust valves (blow-down) is used for the supply of the exhaust gas turbine, the less energy-containing portion of the Ausschiebephase for exhaust gas recirculation.
- DE 199 06 463 C1 discloses a supercharged internal combustion engine with exhaust gas recirculation in a charge air line, from which the cylinders of the engine be fed with compressed charge air.
- the exhaust pressure in the exhaust line of the engine is on average lower than the boost pressure.
- an additional exhaust valve which is independently controlled by the gas exchange valves of the cylinder and which is in communication with the charge air line exhaust passage during the exhaust stroke the cylinder opens as needed.
- AT 003 761 Ul discloses an internal combustion engine with at least one combustion chamber, with an inlet system having at least one intake manifold, with an exhaust system having at least one exhaust system and an exhaust gas recirculation system for recirculating exhaust gases into the intake system, wherein the exhaust gas recirculation system has at least one exhaust gas recirculation line having an exhaust gas recirculation valve.
- the exhaust gas recirculation line branches off directly from the combustion chamber, the exhaust gas recirculation valve being arranged in the area of the branch. Due to the small exhaust gas recirculation valves compared to the intake and exhaust valves, high pressure exhaust gases can be taken directly from the combustion chamber at the end of the high pressure process.
- the object of the invention is to reduce the pollutant emissions of the internal combustion engine in the simplest possible way with good fuel efficiency.
- the closing time of the first valve is varied as a function of at least one engine operating parameter, wherein preferably the opening time of the second valve is varied as a function of at least one engine operating parameter.
- the exhaust path to the exhaust turbine can be completely closed, if necessary.
- the exhaust gas recirculation rate can be set independently of the prevailing pressure levels in all operating states.
- the closing time of the first valve and the opening time of the second valve are varied synchronously.
- the first and second valves open overlapping, wherein the overlapping area can be kept constant with variation of the closing time of the first valve and the opening time of the second valve.
- the distribution of the exhaust gas mass flow between the exhaust gas turbine and the exhaust gas recirculation system can be influenced.
- the opening time of the first valve and the closing time of the second valve is fixed.
- the opening time of the second valve is preferably varied between about 180 ° and 320 ° crank angle.
- the latest closing time of the first valve is equal to the fixed closing time of the second valve.
- the earliest closing time of the first valve results from the earliest opening time of the second valve and the valve overlap.
- the valve overlap is a free parameter which is adapted to the requirements of the respective engine or the respective operating strategy.
- Fig. 1 shows schematically an internal combustion engine for carrying out the method according to the invention
- Fig. 2 is a Ventilhub- crank angle diagram.
- the engine 1 shown schematically in FIG. 1 with a plurality of cylinders 2 has an intake system 3 with an intake manifold 4 and an exhaust system 5 with an exhaust manifold 6, an exhaust gas turbocharger 7 with an exhaust turbine 7a and a compressor 7b, and an exhaust gas recirculation system 8.
- Each cylinder 2 is connected to the exhaust gas turbine 7b via a first valve 9 and a first flow path 10, in which the exhaust gas collector 6 is arranged. the. Furthermore, each cylinder 2 is connected via a second valve 11 to the exhaust gas recirculation system 8.
- the first and second valves 9, 11 phases offset from each other actuated the first valves 9 are each opened in a high pressure phase of the exhaust stroke of the internal combustion engine 1 and the second valves 11 at a later date, for example in the range of the lower dead center. This can be done for example in a low-pressure phase in the second half of the exhaust stroke.
- the valve lift H 9 , Hu of the first valve 9 and the second valve 11 is plotted on the crank angle KW.
- the opening time O 9 of the first valve and the shooting time Sn of the second valve 11 is fixed.
- the closing time S 9 of the first valve 9 and the opening time On of the second valve 11 can be varied, as shown by the dashed and dash-dotted lines for different lifting curves H 9 ', Hn'; H 9 ", Hn" is indicated.
- the open positions of the first and second valves 9, 11 in this case have a valve overlap region 12.
- the times for the closing of the first valve 9 and for the opening of the second valve 11 are varied synchronously, so that the valve overlap 12 of the two valves 9, 11 is always the same.
- the time for the opening of the second valve 11 can be varied in each case between 180 ° and 320 ° crank angle KW.
- the latest closing time of the first valve 9 is equal to the - fixed - closing time of the second valve 11.
- the earliest closing time of the first valve 9 results from the earliest opening time of the second valve 11 and the valve overlap 12th
- the valve overlap is a free parameter which is adapted to the requirements of the respective engine or the respective operating strategy.
- the pressure surge at the beginning of the exhaust stroke is not used to generate the exhaust gas recirculation rate but to increase the power available at the exhaust gas turbine 7b.
- the inventive method is suitable for all supercharged internal combustion engines, but especially for diesel internal combustion engines.
