Definitions
- the invention relates to an exhaust gas turbocharger for an internal combustion engine with a fresh gas supply device.
- the invention also relates to a corresponding arrangement for supplying fresh gas to an internal combustion engine.
- FIG. 1 shows an internal combustion engine 1 according to the prior art, the exhaust pipe 6 is connected to an exhaust gas turbine 12 of an exhaust gas turbocharger 10.
- This exhaust gas turbine 12 drives a compressor 1 1 of the exhaust gas turbocharger 10, in which case the exhaust gas turbine 12 and the compressor 1 1 are coupled via a turbocharger shaft 13.
- the compressor 1 1 compresses intake air from a fresh gas inlet 2 and thus increases an intake pressure in an intake passage 5 of the internal combustion engine 1.
- an acceleration performance of a vehicle, not shown, which is equipped with the internal combustion engine 1 improved.
- a reduction in fuel consumption is achieved.
- Compressor wheels of exhaust gas turbochargers (ATL) in internal combustion engines are made of aluminum or aluminum alloys or titanium or titanium alloys. The reason for this lies in the low specific mass and thus also in a low mass moment of inertia.
- This turbocharger is produced in internal combustion engines with exhaust gas turbochargers therefore, since during an acceleration process, the exhaust gas mass flow from the internal combustion engine 1 through the exhaust gas turbine 12 has to accelerate the compressor 1 1 of the exhaust gas turbocharger 10, The time until the maximum charge pressure is reached depends to a large extent on the inertia of the wheels (the exhaust gas turbine 12 and the compressor 11) . The lower the mass moment of inertia, the more the turbocharger speed is reduced during one Shifting or gear changes (especially in manual transmissions and automated manual transmissions).
- compressed air for example, from a fed from an air compressor 9 compressed air tank 8, controlled in the intake manifold 5 of the internal combustion engine 1 is introduced to cover this with an increased intake air demand of the internal combustion engine 1 this by means of a fresh gas supply device 4, which is arranged between the compressor 1 1 of the turbocharger 10 and a downstream in the flow direction intercooler 3 and the suction line 5.
- WO 2006/089779 A1 describes a device for supplying fresh air to a turbo-charged piston internal combustion engine and a method for operating the same.
- an exhaust gas turbocharger for an internal combustion engine, in particular a diesel engine, with a fresh gas supply device, wherein the exhaust gas turbocharger comprises at least one compressor; at least one exhaust gas turbine; a turbocharger shaft via which the at least one compressor and the at least one exhaust gas turbine are rotatably coupled; and an energy storage device for increasing a moment of inertia, wherein the energy store is rotatably coupled via the turbocharger shaft with the at least one compressor and the at least one exhaust gas turbine.
- One idea of the invention is to equip the exhaust gas turbocharger with an energy store, which increases an inertia of the exhaust gas turbocharger.
- an energy store which increases an inertia of the exhaust gas turbocharger.
- a combination in an arrangement of exhaust gas turbocharger and fresh gas supply device has the advantage that after a gear change the exhaust gas turbocharger is synchronized with the existing engine speed so that an acceleration of the exhaust gas turbocharger to a required for the existing engine speed Turoboladerburnierewert for an associated boost pressure deleted.
- a further advantage is that compressed air consumption of the fresh gas supply device is reduced, since acceleration of the exhaust gas turbocharger after a gear change is dispensed with.
- the energy storage has to a flywheel. He can as a kind
- Be formed flywheel which is rotatably mounted on the turbocharger shaft.
- This flywheel also be at least partially integrated into the turbocharger shaft, which reduces a number of parts. It is also possible that the flywheel of the energy storage is divided so that it is at least partially integrated in rotatable parts of the at least one compressor and / or the at least one exhaust gas turbine. This is possible, for example, when the wheels of the compressor and / or exhaust gas turbine are made of steel.
- the flywheel of the energy storage device can be set for a predetermined delay of the rotational speed of the exhaust gas turbocharger, whereby a compressed air consumption of the fresh gas supply device is reduced. At the same time, the efficiency of the internal combustion engine is increased.
- FIG. 1 is a schematic representation of an internal combustion engine with an exhaust gas turbocharger and a fresh gas supply device according to the prior art
- FIG. 2 shows a schematic representation of an internal combustion engine with an exemplary embodiment of an exhaust gas turbocharger according to the invention and a fresh gas supply device
- 3a-c three diagrams of temporal relationships of a Gangstin- wechseis with engine speed and Turoladerburniere.
- FIG. 2 shows a schematic representation of an internal combustion engine 1 with an exemplary embodiment of an exhaust gas turbocharger 10 according to the invention and a fresh gas supply device 4.
- the exhaust-gas turbocharger 10 has an energy store 14 in the exemplary embodiment shown in FIG.
- the exhaust gas turbocharger 10 according to the invention and the fresh gas supply device 4 form an arrangement for supplying fresh gas to the internal combustion engine 1
- the energy store 14 is coupled to the turbocharger shaft 13 and, in this example, comprises a flywheel which is connected to the compressor 11 and the exhaust gas turbine. ne 12 rotates together when the exhaust gas turbine 12 through the exhaust stream of
- Internal combustion engine 1 is driven.
- the energy storage increases as a flywheel in the manner of a flywheel, the inertia of the compressor 1 1 and the exhaust turbine 12.
- An increase in inertia by the flywheel leads to a significant increase in the turbo lag during acceleration processes as well as when starting the internal combustion engine 1 associated vehicle or when accelerating from low speed without switching operation.
- the exhaust gas turbocharger 10 provided with the energy storage device 14 with the fresh gas supply device 4 shown in FIG. 2 but also by the increased inertia of the wheels of compressor 1 1 and exhaust gas turbine 12 enlarged turbo lag by injection of compressed air by means of Frischgasver- sorgungsvorides 4 in the intake passage 5 of the internal combustion engine 1 almost completely reduced.
- the energy storage 14 may be applied as a centrifugal mass on the turbocharger shaft 13 rotatably. It is also possible that the flywheel is distributed, for example, on two or more flywheels, which are arranged at a suitable position of the turbocharger shaft 13. The energy storage 14 may also be coupled in another way to the turbocharger shaft 13, for example via a clutch and / or a transmission. Of course, the turbocharger shaft 14 may be formed so that the energy storage is integrated in it. The flywheel of the energy accumulator 14 may be selected so that a drop in the rotational speed of the exhaust gas turbocharger, for example, during a gear change, reaches a predetermined value per unit time.
- FIG 3a shows a diagram of gear steps G over the time t.
- a gear stage 5 of an automatic gearbox not shown, is set before a point in time T1.
- Tl a gear change takes place from the gear 5 in gear 7.
- T2 the gear 7 is taken.
- the duration of the gear stage change or the switching operation from Tl to T2 in this example is 2 s.
- FIG. 3 b shows a diagram in which an engine speed n M is schematically plotted over time as a graph section.
- the engine speed n MT1 is 1500 rpm.
- the associated turbocharger speed n L is shown in FIG. 3c in a further diagram.
- the turbocharger speed n LT1 is 150000 rpm.
- the flywheel is predetermined so that the exhaust gas turbocharger 10 is braked during the switching operation of 2 s by 40000 U / s. In this way, after a switching operation of 2 s at time T2, the optimum turbocharger speed n ' LT2 , which is now synchronized to the existing engine speed n MT2 . It is then no unnecessary high acceleration of the exhaust gas turbocharger 10 more necessary, a turbo lag does not occur.
- the flywheel of the energy accumulator 14 increases the turbo lag when starting from an idle speed of the internal combustion engine 1 or when accelerating from low engine speed n M without switching operation. However, this effect is completely eliminated by the fresh gas supply device 4.
- the turbocharger speed n LT2 is synchronized with the engine speed n MT2 and no longer needs to be accelerated, the air consumption in the insufflation process of compressed air is reduced by the fresh gas supply device. It follows that a necessary adaptation of the air compressor 9 or an air drying system, for example, in a commercial vehicle is avoidable and provides a cost savings.
- the energy store 14 may be subsequently attachable to exhaust gas turbochargers 10 prepared therefor, e.g. via a corresponding coupling, or can be mounted therein.
- the impellers of compressor 1 1 and / or exhaust turbine 12 may be made of a heavier material than aluminum or titanium, such as steel. As a result, additional flywheel mass of the energy store 14 can be reduced.
- turbocharger shaft 13 can be coupled in order to adapt the mass moment of inertia to different operating conditions of the internal combustion engine 1.
