Definitions
- the invention relates to an arrangement for supplying fresh gas to a turbo-charged internal combustion engine.
- the invention also relates to a method for controlling such an arrangement.
- Internal combustion engines such as diesel engines, are very often equipped with exhaust gas turbochargers.
- a drive impeller driven by an exhaust flow of the internal combustion engine drives a compressor impeller to compress fresh gas.
- Compressor wheels are made of aluminum or
- Aluminum alloys produced This has its cause in particular in the lower specific mass and thus also low moment of inertia, which is particularly important in torque requirements, ie during acceleration of the internal combustion engine, because the exhaust gas turbocharger can not promote sufficient air in each operating state of the internal combustion engine and thus produce a sufficient intake pressure.
- turbo lag an operating state during acceleration
- the internal combustion engine reacts when accelerating with a speed increase after a certain delay time, in which no exhaust gas energy, ie no sufficient exhaust gas pressure
- the exhaust gas mass flow must accelerate the turbocharger until it can build up its full boost pressure
- Reaching the maximum charge pressure or charge air pressure depends to a large extent on the mass inertia of the impellers (compressor impeller, drive wheel or turbine) of the turbocharger.
- Fresh gas is here to be understood as intake air.
- Compressed air is to be distinguished from it, it is produced separately, for example by means of a compressor and in one
- Container stored.
- Charge air is the intake air compressed by the turbocharger or the fresh gas compressed by it.
- EGR exhaust gas recirculation
- the object is achieved by an arrangement for fresh gas supply with the features of claim 1. It is also achieved by a method having the features of claim 8.
- an arrangement for supplying fresh gas to a turbo charged internal combustion engine having an intake pipe and an exhaust pipe comprising: an exhaust gas turbocharger with at least one compressor impeller for compression of fresh gas and supply of the compressed fresh gas to the internal combustion engine, and with at least one drive impeller for driving by exhaust gas of the internal combustion engine for Drive of the compressor impeller; and a compressed air supply means for controlled supply of compressed fresh gas or compressed air to the internal combustion engine, the Dmclduftzuschreib founded upon a charge air inlet to the compressor impeller, with an outlet to the intake manifold and to a compressed air inlet to a compressed air source, wholly or partly made of steel or a steel alloy ,
- the entire at least one compressor impeller of the exhaust gas turbocharger is formed from steel.
- Aluminum or titanium takes a far longer time than the steel impeller needed to reach the optimum speed. This also results in an advantageous fuel economy.
- Another advantage of the steel compressor wheels is the significantly higher robustness. This in turn allows higher speeds and higher pressure ratios of the turbocharger. In addition, it may be possible to reduce the number of charge stages required (e.g., reducing a two-stage loader to a single-stage loader). Thus, further costs, weight and space can be saved.
- the Dmckluftzubuch Kunststoff Kunststoffbuch für the Dmck Kunststoffzubuch thanks is formed with valves for the controlled supply of compressed air to the internal combustion engine when a pressure of the compacted from the compressor fresh gas in at least one specific operating state of the internal combustion engine falls below a predetermined value.
- the valves can be controlled by a control device of the compressed air supply device.
- the arrangement has a control device for controlling the compressed air supply device and for determining operating parameters of the exhaust gas turbocharger.
- the existing operating parameters of a motor control can be used in the vehicle. It is also conceivable that such a controller can be integrated in the engine control.
- the compressed air source may, for example, have a compressed air tank and a compressed air compressor feeding it. Other compressed air sources, such as an electric air compressor without storage are possible.
- the arrangement may have a charge air cooler, which is arranged between the compressor impeller of the exhaust gas turbocharger and the compressed air supply device, and also an exhaust gas recirculation.
- An inventive method for controlling the arrangement described above comprises the following method steps: determining the respective operating parameters of the internal combustion engine and an exhaust gas turbocharger by a control device and / or a motor control; Supplying compressed air by means of a compressed air supply device controlled by the control device to the internal combustion engine when a charge air pressure of the exhaust gas turbocharger is below a pressure value required according to the respectively determined operating parameters; or supplying charge air of the exhaust gas turbocharger to the internal combustion engine.
- FIG. 1 shows a schematic representation of an internal combustion engine with an arrangement according to the invention for fresh gas supply
- Fig. 2 is a graph of motor torques.
- the exhaust gas turbocharger 2 has a compressor impeller 4, which is rotatably coupled to the drive wheel 5.
- the compressor impeller 4 compresses fresh gas from a fresh gas inlet 2 to increase an intake pressure in an intake passage 14 for the internal combustion engine 1, whereby, for example, an acceleration behavior of Vehicle with the internal combustion engine 1 and a reduction in energy consumption can be achieved.
- the compressor impeller 4 is driven by the drive impeller 5, which is for example a turbine, which is driven by the exhaust gas of the internal combustion engine 1 and is arranged in the exhaust pipe 15 in the flow direction in front of an exhaust gas outlet 16.
- a compressed air inlet 11 is connected to the outlet 13 and via a valve via a compressed air line 12 to a compressed air source, which here is a compressed air tank 8, fed by a driven by the internal combustion engine 1 air compressor 9.
- a control device serves to control the valve and the flap element, also not shown. It is also connected here with pressure sensors, also not shown, in the outlet 13 and charge air inlet 10.
- the compressed air valve opens the connection from the compressed air inlet 11 to the outlet 13.
- the controlled flap element is closed, so that the compressed air is not supplied via the charge air inlet 10 can flow into the exhaust gas turbocharger 2 in the opposite direction to the suction direction, but flows directed into the suction line 14 via the outlet 13.
- this flap element is opened again and the valve is closed to the compressed air line 12. At this point in time, the charge air pressure through the exhaust gas turbocharger 2 is restored sufficient.
- FIG. 2 shows a graphical representation which illustrates an engine torque of the internal combustion engine 1 over the time t for different compressor wheels 4 with different materials in different combinations of arrangements for supplying fresh gas to the internal combustion engine 1.
- the curve 17 represents a first engine torque curve 17 in which a compressor impeller 4 made of steel is used and no arrangement according to the invention with a compressed air supply device 7 is present.
- a 90% motor torque M90 is reached only at a time t4.
- a time t3 which is achieved by a compressor impeller made of titanium, also without the inventive arrangement with a compressed air supply means 7, a second engine torque curve 18.
- Without the inventive arrangement with a compressed air supply device 7 is by means of a compressor impeller 4 made of aluminum with a third engine torque curve 19 an even earlier
- Time t2 achieved to reach the 90% motor torque M90. If now the arrangement according to the invention is used with a compressed air supply device 7 simultaneously with a compressor impeller 4 made of steel, then the fourth engine torque curve 20 results with the earliest time tl to reach the 90% motor torque despite a much higher mass moment of inertia of the compressor impeller 4 with respect to the other wheels the state of the art.
- the compressor impeller 4 may even be made of any material, with steel being advantageous in terms of fatigue strength and temperature resistance, cost and benefits in the application described above.
- a control device can also be provided with stored table values for different operating states of the internal combustion engine 1 and the exhaust gas turbocharger 2 in order to set the optimum value for compressed air supply and charge air for the internal combustion engine 1 for each operating state.
