Definitions
- the invention relates to a compressor according to the preamble of claim 1.
- the compressor has a variably adjustable diffuser geometry, which allows, depending on the current operating point of the compressor Changing the geometry of the diffuser downstream of the compressor wheel.
- the diffuser geometry comprises circumferentially distributed diffuser vanes which are each rotatably mounted on a vane shaft and a rotatable adjusting ring with adjusters which rotate the vane shafts about their longitudinal axes, thereby reducing the position of the vanes .
- Guide vanes is changeable and therefore different flow conditions are set in the diffuser.
- the invention is based on the problem to provide a generic compressor with variably adjustable diffuser geometry, which is characterized by a simple structural design and exact Einstellm ⁇ grete.
- the adjustment of the diffuser geometry should be accomplished with high security against jamming or distortion and with low restoring forces.
- the compressor has in the region of the diffuser geometry an adjusting ring with adjusting elements, which act on the guide vanes of the diffuser geometry at a distance from the respective guide shaft in the direction of rotation.
- the force acting on the vanes actuating force of the adjusting causes a torque about the guide vane shaft, which leads to the adjustment of the vanes.
- the guide vane is now subjected to the adjusting force at a distance from its guide vane shaft. be required for the adjustment of the vanes only lower and better dosable actuating forces.
- the useful ring-shaped distributed vanes are acted upon by the adjusting elements in particular in a radially outer region, which has a greater distance from the longitudinal axis of the diffuser geometry than the guide vane shafts.
- FIG. 1 shows a section through an exhaust gas turbocharger with a compressor and an exhaust gas turbine, wherein the compressor in the region of the Ver Whyrradaustrittes a diffuser with variably adjustable Diffusorge- geometry has,
- the rotational movement of the turbine wheel 5 is transmitted via a shaft 8 to a compressor 9 in the compressor housing 15, compressed by the rotational movement of the compressor wheel 9 via an inflow channel 10 combustion air compressed to an increased boost pressure and is discharged on the Abstr ⁇ mseite the compressor in a radial diffuser 11 ,
- the diffuser 11 opens into a helical calming channel 12, from which the compressed air is discharged from the compressor and over which Suction line is supplied to the cylinders of the internal combustion engine.
- the diffuser 11 is embodied as a radially extending, annular outflow channel between the radial outflow region of the compressor wheel 9 and the settling channel 12 and has a variably adjustable diffuser geometry 13, via which the effective cross section of the diffuser 11 as a function of state and operating variables of the internal combustion engine or from the internal combustion engine associated units is adjustable.
- the flow cross section of the diffuser is changed by acting on the variable diffuser geometry, in particular to increase the compressor working range. This makes it possible to stabilize the compressor operation in the boundary region of the still permissible compressor working range near the stuffing limit, but in particular near the surge limit, so that an inadmissible exceeding the surge limit and thus an undesirable compressor pumps can be avoided.
- the adjusting ring 19 has a plurality of adjusting elements 20, which are designed as pins and are located on an axial end face of the adjusting ring 19, wherein in each case an adjusting element 20 of a guide blade 16 is assigned to the bearing ring 18.
- the adjusting ring 19 is acted upon by a designed as a push rod actuator 21 and pivoted about its axis of rotation.
- the actuator 21 is actuated by an actuator, not shown.
- the adjusting elements 20 on the adjusting ring 19 are adjusted in the circumferential direction by a predetermined angle, whereupon the guide vanes 16 on the bearing ring 18 are pivoted about their guide blade shafts 17 by a corresponding angular amount.
- the free flow cross section between each two adjacent vanes changes, whereby the pressure ratio between the compressor inlet side and the compressor outlet side changes and in particular the operation of the compressor near the surge line can be affected.
- the guide vane shafts 17 of the guide vanes 16 have a smaller distance from the axis of the bearing ring 18 or the adjusting ring 19 than the adjusting elements 20 on the adjusting ring, which has the consequence that already a relatively small, acting in the circumferential direction of the adjusting force for pivoting the guide vanes to the guide vane shafts enough .
- Each vane 16 is fork-shaped and has two forks 22 and 23, between which a radially outwardly open receptacle 24 is formed, into which in each position of the adjusting 19, the adjusting element 20 protrudes. This ensures that in an adjustment of the adjusting ring 19 in the direction of arrow 25 in each position of the adjusting ring, the movement of the guide vanes 16 is forcibly guided.
- variable diffuser allows by the free adjustability of the adjustable vanes from the respective operating point individually demand-dependent control or controllability of the motor air mass to be supplied or the air ratio ⁇ .
- the particle filter regeneration can be supported by short-term reduction of the air ratio ⁇ and concomitant increase in the engine exhaust temperature of the exhaust gases.
- an individually demand-dependent catalyst operating temperature is adjustable.
- the engine temperature in the starting area can mitigation and raising the catalyst operating temperature can be raised. Increasing the engine temperature in certain operating ranges can also increase the conversion rate when using an SCR system.
- the variable diffuser also allows the exhaust gas turbocharger speed to be reduced in the event of a larger compressor being used without degrading the surge limit of the compressor.
