- the present invention relates to an internal combustion engine and a method for operating an internal combustion engine.
- FIG. 1 shows a first exemplary embodiment of an internal combustion engine 10 according to the invention, which comprises a plurality of cylinders 11 and a charging device 12.
- the charging device 12 has a turbine 13, in which exhaust gas, which leaves the cylinder 1 1 of the internal combustion engine 10, is relaxed. In the relaxation of the exhaust gas in the turbine 13 recovered energy is used in a compressor 14 of the supercharger 12 to compress the cylinders 1 1 to be supplied charge air in the compressor 14. Between the compressor 14 of the charging device 12 and the cylinder 1 1 of the internal combustion engine 10 while a charge air cooler 15 of the charging device 12 is connected to cool the compressed charge air before the introduction of the same into the cylinders 1 1 of the internal combustion engine 10.
- the internal combustion engine 10 of Figure 1 has a pressure vessel 16, which is associated with a valve 17, wherein when the valve 17 is closed, in the pressure vessel 16 held compressed air can not escape from the pressure vessel 16. In contrast, when the valve 17 is opened, the compressed air stored in the pressure vessel 16 can escape from the same.
- the compressed air stored in the pressure vessel 16 can be conducted to open the valve 17 in the direction of the cylinders 11 of the internal combustion engine 10 to accelerate the run-up of the internal combustion engine 10. It is provided in the embodiment of FIG. 1, to introduce the compressed air directly into the compressor 14 of the charging device 12. Simultaneously with the opening of the valve 17 of the compressed air tank 16, a fuel supply to the internal combustion engine 10 is increased in order to accelerate the run-up of the internal combustion engine.
- the opening of the valve 17 of the compressed air tank 16 and thus the conduction of the compressed air in the direction of the cylinder 1 1 of the engine 10 and increasing the fuel supply to the engine 10 is preferably carried out directly with or immediately after activation of a starting device of the internal combustion engine 10th
- Fig. 2 shows an alternative embodiment of an internal combustion engine 10 according to the invention, in which for accelerating the run-up of the internal combustion engine 10, the stored compressed air in the pressure vessel 16 by opening the valve 17 in a charge air line 18 can be introduced, extending between the compressor 14 and the Charge air cooler 15 of the charging device 12 extends. Simultaneously with the opening of the valve 17 of the compressed air tank 16, a fuel supply to the internal combustion engine 10 is increased in order to accelerate the run-up of the internal combustion engine 10.
- Fig. 3 shows a further variant of an internal combustion engine 10 according to the invention, in which the compressed air stored in the pressure vessel 16 with open valve 17 to accelerate the run-up of the internal combustion engine 10 on the one hand in a charge air line 19 can be introduced, extending between the intercooler 15 and the cylinders 1 1 the internal combustion engine extends, and on the other hand indirectly on the cylinder 1 1 of the internal combustion engine 10 can be introduced.
- the compressed air either exclusively indirectly in the cylinder 1 1 or in the charge air line 19. Simultaneously with the opening of the valve 17 of the compressed air tank 16, a fuel supply to the internal combustion engine 10 is increased in order to accelerate the run-up of the internal combustion engine 10.
- the compressed air stored in the pressure vessel 16 is introduced with the valve 17 open on the one hand directly into the compressor 14 of the charging device 12 and on the other hand into the charge air line 19 extending between the charge air cooler 15 and the cylinders 11 can be to accelerate the run-up of the internal combustion engine.
- a fuel supply to the internal combustion engine 10 is increased in order to accelerate the run-up of the internal combustion engine 10.
- FIG. 5 shows a variant in which the compressed air stored in the pressure vessel 16 can be conducted in four directions in the direction of the cylinders 11 with the valve 17 open, namely directly into the compressor 14 of the charging device 12, into the charge air lines 18 and 19 and directly into the cylinder 1 1 of the internal combustion engine 10. It should be noted at this point that any combination of these feed points for the compressed air can be used. Thus, it is possible to store the compressed air stored in the pressure vessel 16 at one, at any two, at any three or at all four in FIG. 5
- the internal combustion engines of FIGS. 1 to 5 are in each case turbocharged internal combustion engines whose charging device 12 comprises a single exhaust gas turbocharger with a turbine 13 and a compressor 14.
- the charging device 12 it is also possible for the charging device 12 to have a multi-stage design, that is to say a plurality of exhaust gas turbochargers and thus several turbines as well as a plurality of compressors.
- the invention of FIG. 6 can be used on a non-supercharged internal combustion engine 10, wherein in such a non-supercharged internal combustion engine 10 to accelerate the run-up of the same in the pressure vessel 16 held compressed air with the valve open 17 in the direction of the cylinder 1 1 of the internal combustion engine 10 is, in accordance with FIG. 6 in a leading to the cylinders 1 1 charge air line 20 and / or directly into the cylinder 1 first
- more than one pressure vessel 16 may be present. It is thus possible to assign a separate pressure vessel 16 with a separate valve 17 to each feed point for the compressed air. It is also possible to assign a common valve 17 to a plurality of pressure vessels 16.
- compressed air stored in at least one compressed-air reservoir 16 is thus directed in the direction of the cylinders 11 of the internal combustion engine 10. Simultaneously with the opening of the valve 17 of the compressed air tank 16, a fuel supply to the cylinders 1 1 of the internal combustion engine 10 is preferably increased.
