Definitions
- the invention relates to an internal combustion engine with an intake system according to the preamble of claim 1.
- the object of the invention is to provide an intake system for an internal combustion engine which, in addition to reducing airborne noise, also causes a reduction in pollutant emissions.
- the opening of the nozzle is arranged at a defined distance from the center of gravity of the interior volume of the container of the intake system.
- the connecting piece can advantageously also have an oblique opening, which brings about an increased mixing of the flows from the pollutant reducing device and from the suction connecting piece.
- a narrowing of the pipe in the manner of a diffuser in the region of the inlet of the pipe socket is effected in the intake pipe in the region of the constriction to increase the flow velocity of the gas stream from 'the intake manifold, thereby generating an additional flow of gas from the emission control device and causes a mixing effect.
- FIG. 1 shows a section through a container of an intake system with an inserted intake pipe and associated pollutant reduction device with a connected connecting piece
- F.ig. 3 shows the sound pressure in the interior of the container on the lowest energy vibration form of the air volume
- FIG. 4 shows a sectional illustration of the container of the intake system with connected pollutant reduction device
- Fig. 5 views of the beveled protruding into the intake pipe and 6 nozzle of the pollutant reduction device
- Fig. 7 shows an embodiment of the intake pipe as a diffuser with a connected nozzle.
- the internal combustion engine comprises an intake system with a container 1, the interior A of which is connected to a cylinder head via individual intake pipes 2, 3, 4 and 5.
- An intake port 6 of the container 1 is connected to a projecting intake pipe 7 for air supply, which is connected to an air supply system.
- a pollutant reduction device R is connected to the interior A of the container 1 via a pipe socket 8, said device comprising at least one exhaust gas recirculation device 9, a housing ventilation system 10, an additional air supply system 11 and a fuel vapor collection system 12.
- the pipe branch 8 branching off from the pollutant reduction system R is shown in more detail, which is located in front of the free end of the pipe 7 with its opening 14 in a plane 0-0 of the container cross section, which is approximately through the center of gravity SP of the inner volume of the container 1 runs.
- the pipe socket 8 has a radius r and is connected to at least one or more of the systems 9, 10, 11 or 12.
- the gas volume in the interior A of the container 1 can be regarded as a mass distributed in the volume which has its own elastic characteristic values. This mass is stimulated by the individual intake pipes 2 to 5, which are connected to the individual engine cylinders, and by the pipe socket 8 of the pollutant reduction device R. This excitation causes the gas volume in interior A to start vibrating in the natural frequency range.
- this increases the pulsation intensity of the pressures in the lines of the pollutant reduction device R and on the other hand it increases Sound radiation to the environment by means of the components that connect the gas pipes of the engine to the outside.
- the arrangement according to the invention is intended either to rule out the influence of the gas volume vibrations in room A in the most energy-intensive natural resonance forms on the acoustic and gas dynamic processes, or in any case to substantially reduce them, in order to improve the pollutant properties of the engine.
- the mouth 14 of the pipe socket 8 of the pollutant reduction device R is connected to the interior A of the container 1 in the plane 0-0, which corresponds to the plane of the cross section of the container 1 and through the center of gravity SP of the volume of the room A in the engine of the container 1 runs.
- the acoustic energy of the waveform to be considered (and all other analog, non-straight waveforms) is not transmitted from the interior A via the orifice 14 and further into the environment, which leads to an improvement in the acoustic motor properties.
- the effectiveness is increased if the dynamic flow pattern in front of the mouth opening 14 of the pipe socket 8 is merged with the center of gravity SP of the volume of the container 1. With this flow pattern, the influence of the dynamic process that takes place in the pipe socket 8 can be taken into account in a defined manner.
- the focal point of the level of the output speeds of the gas stream pulsating in the pipe socket 8 is preferably in the infinite space at a distance of 0.6 r in front of the opening of the nozzle 8. The distance can effectively be in a range from 0.4 to 0.8 r, which is related to the scatter of design, process engineering and other factors.
- the position of the dynamic flow in front of the nozzle 8 in the room excludes the excitation of the gas volume in room A in the nozzle 8 with the lowest Self-oscillation form (from Fig. 3), ie the most energy-intensive form, which increases the acoustic characteristics of the motor accordingly.
- the pipe socket 8 with its outlet opening 14 opens into the interior B of the pipe 7 with the intake pipe 6 for air supply.
- the pipe socket 8 has a bevel 25 or 26 at its free end, so that, according to the embodiment according to FIG. 5, the oblique mouth opening 14 of the inlet opening 21 of the suction nozzle 6 is trimmed. In the further embodiment according to FIG. 6, the oblique opening 14 of the opening 21 is turned away.
- FIG. 7 shows an embodiment of an intake pipe 7 which acts as a diffuser.
- the area of the pipe 7 into which the pipe socket 8 opens is provided with a cross-sectional reduction 23.
- the gases flow from the systems 9 to 12 via the pipe socket 8 of the pollutant reduction device R into the cavity B of the tube 7.
- the gas flow in the recirculation system 9 and in the housing ventilation system 10 is at a considerable temperature, as a result of which intense heat is generated in the cavity B. - and mass exchange of the gas stream from plants 9 to 12 takes place, as well as their effective mixing.
- the gas flow mentioned gives off part of its heat to the power flow mixture entering the engine cylinder, as a result of which the evaporability of the liquid phases of the fuel mixture is increased and the mixture becomes fine, disperse and homogeneous.
- this leads to a more even distribution of the end product to the engine cylinder, which consists of a fuel mixture with a gas stream from the pollutant reduction device R, and to better combustion of the operating charge of the mixture in the cylinders and, consequently, to the pollutant reduction of the engine.
- the flow rate of air is increased from the air cleaning system and air delivery system in this region and thereby an additional gae 'szustrom of the pollutant reduction device R generated and moreover is an additional possibility to control of the volume throughput of these gases is created, whereby the mixing effect of the gas stream with the gas stream from the pollutant reduction device R can be enhanced.
