Definitions
- Turbocharger device and a method for operating a turbocharger device
- the invention relates to a turbocharger device and a method for operating a turbocharger device according to the preambles of the independent claims.
- a turbocharger device with two exhaust gas turbochargers in which the exhaust gas mass flow can be switched over.
- the exhaust gas mass flow is directed through both turbines, while at high engine speeds, the high-pressure turbine is bypassed and the exhaust gas mass flow is directed only through the low-pressure turbine.
- the exhaust gas mass flow is switched over in such a way that a minimal exhaust gas mass flow always flows through the high-pressure turbine, even at high engine speeds.
- variable partial flows of the exhaust gas mass flow are divided between the high pressure turbine, the low pressure turbine and the fresh air side with exhaust gas recirculation of the internal combustion engine.
- the object of the invention is to provide a turbocharger device and a method for operating such a turbocharger device, in which a further improvement with regard to pollutant emissions is possible.
- the object is achieved according to the invention by the features of the independent claims.
- a series circuit comprising a turbine and a first exhaust gas catalytic converter is provided in the exhaust gas line, wherein a switchable bypass line through which the exhaust gas mass flow can flow is provided, which branches off from the exhaust gas line upstream of the series circuit and re-opens into the exhaust line in an outlet downstream of the series circuit.
- Exhaust gas temperatures that are too low can be avoided, which lie outside the optimum range of the operating temperature for the conversion of pollutants contained in the exhaust gas, such as hydrocarbons and carbon monoxides, of the exhaust gas cleaning device. Due to the series connection of the turbine and the first exhaust gas catalytic converter and the switchable bypass of the series connection, no additional components are required which switch over an exhaust gas mass flow through the first exhaust gas catalytic converter, since a switchover that is usually present is also used for the turbine.
- the exhaust gas catalytic converter connects downstream of the turbine. This is advantageous since the exhaust gas energy in the turbine can be used essentially undisturbed.
- a regular catalytic exhaust gas cleaning device is provided downstream of the junction.
- a light-off temperature of the catalytic reaction in the first exhaust gas catalytic converter can be achieved much more quickly than with conventional systems. Therefore, an effective conversion of the pollutants takes place in the exhaust gas, even if the regular exhaust gas cleaning device should not yet be at its operating temperature.
- the first exhaust gas catalytic converter can be designed smaller, since it only has to be designed for medium mass flows. In this way, an increasing exhaust gas back pressure can be specifically optimized.
- the design of the regular exhaust gas purification device can also be adapted, taking into account the pre-cleaning in the first exhaust gas catalytic converter, and possibly smaller or designed with less catalytic material.
- At least two exhaust gas turbochargers are provided, the turbines of which the exhaust gas mass flow can flow through in succession in the direction of flow. This enables a two-stage supercharging of the internal combustion engine with high dynamics.
- a second switchable bypass line is preferably provided, which branches off from the exhaust line downstream of the first series connection and opens into the exhaust line downstream of a second turbine. This enables flexible adjustment of the exhaust gas mass flows which act on the turbines of the exhaust gas turbocharger.
- At least two exhaust gas turbochargers are provided, at least one of which has a double flow, so that the exhaust gas mass flow can flow through its turbines in parallel.
- the favorable light-off behavior of the exhaust gas catalytic converter or the upstream of a regular exhaust gas purification device can thus also be used in a multi-fluid arrangement.
- two turbines can be assigned a common exhaust gas catalytic converter, which is favorable for installation space and costs.
- At least one further series circuit comprising a further exhaust gas catalytic converter and a further turbine is used, which can be bypassed with a further bypass line through which the exhaust gas mass flow can flow.
- the light-off behavior of the catalytic reaction in the exhaust gas catalytic converter or the upstream of the regular exhaust gas cleaning device can thus be favorably influenced.
- the method according to the invention for operating a turbocharger device is characterized in that the exhaust gas mass flow is precleaned by a turbine and a first exhaust gas catalytic converter when it passes through a series connection before it is fed to a further catalytic exhaust gas cleaning device.
- the exhaust gas mass flow is conducted at high engine speeds essentially through the bypass line of a high-pressure turbine and drives a low-pressure turbine, whereby in a further advantageous development a residual flow of the exhaust gas mass flow keeps the first exhaust gas catalytic converter at an elevated temperature.
- the exhaust gas catalytic converter is therefore essentially permanently ready for operation when the internal combustion engine is running.
- Fig. 1 shows an arrangement of the internal combustion engine and two in
- Fig. 2 shows a preferred double-flow arrangement with double-flow high-pressure stage and single-flow
- An internal combustion engine 1 has exhaust gas-side pipelines 2, through which an exhaust gas mass flow is carried away from the internal combustion engine 1, and supply air-side pipelines 3, with which combustion air is supplied to the internal combustion engine 1.
- two exhaust gas turbochargers are provided.
- air supply line 13 air flows in the flow direction S2 and is compressed by compressors 5, 8 of the exhaust gas turbocharger.
- Exhaust gas flows from the internal combustion engine 1 in an exhaust line 15 in the flow direction SI.
- Turbines 4, 7 of the two exhaust gas turbochargers are arranged in the exhaust line 15 and are driven by the exhaust gas mass flow.
- the turbocharger which is arranged downstream of the internal combustion engine 1 in relation to the exhaust gas flow, expediently has a turbine 4, preferably a high-pressure turbine, while the following exhaust-gas turbocharger has a turbine 7 as a low-pressure turbine.
- the two turbines 4, 7 can be of different sizes, the low-pressure turbine being larger than the high-pressure turbine.
- the turbine 4 drives the compressor 5 over a shaft 6, the turbine 7 drives the compressor 8 via a shaft 9.
- An exhaust gas recirculation is provided in the air supply line 13, an exhaust gas mass flow of the air, in particular the combustion air, being supplied via an exhaust gas line 10. The amount of the admixed exhaust gas mass flow can be adjusted as required by means of an adjusting means 11.
- a charge air cooler 12 is provided in the air supply line 13, which cools the compressed air to a desired temperature.
- a confluence of the exhaust gas mass flow in the air supply line 13 can be provided between the two compressors 5, 8, downstream of the compressor 5 or also downstream of the charge air cooler 12. Additional coolers can optionally be provided, for example after each compressor, in particular if more than two exhaust gas turbochargers are provided.
- a series circuit 22 comprising a turbine 4 and a first exhaust gas catalytic converter 20 is preferably provided in the exhaust line 15, a switchable bypass line 16 through which the exhaust gas mass flow can flow being provided, which branches off from the exhaust line 15 upstream of the arrangement and in a junction 14 downstream of the arrangement in the exhaust pipe 15 opens again.
- a first actuating means 17 is provided, which releases or blocks the cross section of the bypass line 16. In a favorable further development it can be provided that the adjusting means 17 releases or blocks the cross section step by step or continuously.
- the exhaust gas catalytic converter 20 adjoins the turbine 4 downstream, preferably directly.
- the first exhaust gas catalytic converter 20 can also be arranged upstream of the turbine 4. This position is shown in dashed lines in the figure. Downstream of the junction 14 is one Catalytic exhaust gas purification device 21 is provided, in which the regular exhaust gas purification takes place. A special switching unit for the exhaust gas mass flows is not required due to the existing actuator 17 in the context of a multi-stage charging.
- the first exhaust gas catalytic converter 20 is therefore flowed through when the flow through the turbine 4 is released as required by a control unit (not shown). If there is no flow through the turbine 4 or only a small exhaust gas mass flow is applied, the first exhaust gas catalytic converter 20 is likewise not supplied or a small exhaust gas mass flow is applied.
- the exhaust gas mass flow flows successively through the turbines 4, 7 in the direction of flow SI, turbine 4 being assigned to the high-pressure stage and turbine 7 to the low-pressure stage.
- a second switchable bypass line 18 is provided, which branches off from the exhaust line 15 downstream of the first series circuit 22 and opens into the exhaust line 15 downstream of the second turbine 7.
- each turbine 4, 4 ' forms a series circuit 22, 22' with a first exhaust gas catalytic converter 20, 20 '.
- Both series circuits 22, 22 'each have a switchable bypass line 16, 16', the cross section of which is released or blocked by actuating means 17, 17 '.
- a common exhaust gas catalytic converter 20 can be assigned to the two turbines 4, 4 '.
- the Exhaust gas catalytic converter 20 or the exhaust gas catalytic converters 20, 20 ′ are arranged downstream of the turbine 4 or the turbines 4, 4 ′.
- the exhaust gas catalytic converter 20 or the exhaust gas catalytic converters 20, 20 ′ can also be arranged upstream of the turbine 4 or the turbines 4, 4 ′.
- the second stage is a single-flow, low-pressure stage and comprises an exhaust gas turbocharger with a turbine 7, which drives a compressor 8 via a shaft 9.
- this exhaust gas turbocharger can also be designed with two passages.
- At least one further series circuit 22, 22 ′ is preferably provided, comprising a further exhaust gas catalytic converter and a further turbine, which can be bypassed with a further bypass line through which the exhaust gas mass flow can flow.
- an exhaust gas mass flow at least temporarily drives a turbine 4, 4 ', 7, the exhaust gas mass flow being at least partially switchable between an exhaust line 15, 15' and a bypass line 16, 16 'depending on operating parameters, and the exhaust gas mass flow being passed through Series circuit 22, 22 'of a turbine 4, 4' and a first exhaust gas catalytic converter 20, 20 'is pre-cleaned before it is fed to a further catalytic exhaust gas purification device 21.
- the exhaust gas mass flow at high speeds of the internal combustion engine 1 is essentially passed through the bypass line 16 of a high-pressure turbine and drives a low-pressure turbine downstream, so that only the low-pressure stage is used to build up the boost pressure of the combustion air.
- Both, or preferably all, exhaust gas turbochargers are in operation in the low speed range.
- the first exhaust gas catalytic converter (s) 20, 20 ' which are provided in series connections with turbines 4 and / or 4' and which are particularly preferably arranged between the high pressure turbine and the low pressure turbine, high conversion rates of pollutants in the exhaust gas can be achieved quickly , In this case, it may be sufficient to design the exhaust gas catalytic converter 20, 20 ′ with regard to the exhaust gas counterpressure only for the correspondingly lower air mass flows on the exhaust gas side.
- a residual flow of the exhaust-gas mass flow via the high-pressure turbine can ensure a constantly high temperature level in the exhaust-gas catalytic converter 20, 20 ', so that it can be used practically immediately, for example at low speeds, both or all, exhaust gas turbochargers are put into operation.
- the first exhaust gas catalytic converter 20, 20 ′ is connected upstream of the regular exhaust gas cleaning device 21, component masses lying between the internal combustion engine and the exhaust gas cleaning device 21 interfere less with regard to the exhaust gas temperature, and an improved pollutant reduction is achieved. This applies in particular to highly dynamic driving cycles in which there is a risk that the regular exhaust gas cleaning device 21 can only reach the operating temperature at relatively low temperatures or only with a delay.
