Definitions
- the charging devices can be configured as exhaust gas turbochargers or else as pressure wave superchargers and increase the pressure level in the intake tract of an internal combustion engine in order to achieve a higher degree of filling of the cylinders when the intake valves of the internal combustion engine are open.
- exhaust gas turbochargers At low speeds of the internal combustion engines occurs in exhaust gas turbochargers on the "Tur ⁇ boloch" because due to the lower exhaust gas flow output from the turbine to the compressor impeller of the exhaust gas turbocharger mechanical power for Druckhö ⁇ hung in the intake of the internal combustion engine is no longer sufficient.
- turbo lag occurs in the lower speed range of the internal combustion engine.
- the exhaust gas volume flow produced by the internal combustion engine is not sufficient to drive the compressor impeller of the exhaust gas turbocharger at a speed which could lead to a significant pressure increase in the intake tract of the internal combustion engine.
- exhaust-gas turbocharger for example electrically drivable additional aggregates, which can be connected via an overrunning clutch, for example, when a certain lower rpm value of the internal combustion engine has been reached. exceeding a certain turbo lag avoiding speed of combustion can be discarded again, which can be done for example via a freewheel clutch or an overrunning clutch or the like.
- remedial option presented above therefore represents a not inconsiderable expense with regard to the components to be used and with regard to the stress on additional installation space in the engine compartment of an internal combustion engine.
- Pulse loaders are known in the art. Impulse loaders are arranged in the intake tract of an internal combustion engine on the inlet side of the internal combustion engine.
- the impulse loaders used hitherto operate on the flap principle and have a flap mimic integrated into the charge air feed to the internal combustion engine.
- the flap principle used has the considerable disadvantage that the stability of the flaps as a result of the extremely short switching times and the frequent mechanical contact with stop surfaces still fails unsatisfactory.
- the frequent striking of the driven flaps of such impulse loaders on the wall of the charge air supply is on the one hand accompanied by mechanical wear, and on the other hand leads to a not inconsiderable noise development in the intake tract.
- the wear occurring with increasing operating time of the internal combustion engine on the flaps of the impulse loader causes the flaps to no longer be completely sealed in the closed state and an air flow of the charge air increasing along the length of the flaps no longer tightly closes over time which adversely affects the efficiency of a pulse charger of this type in the intake tract of an internal combustion engine.
- the volume of the impulse charger is relatively large, to cover the entire opening cross section of the charge air.
- these have the disadvantage of large moving masses, so that their use makes considerable demands on the drive and on the other hand leads to large moments of inertia. Short switching times can be achieved with difficulty designed as a roller rotary valve impulse chargers.
- a pulse loader which can be used in the intake tract of an internal combustion engine with a pair of rotary slide elements.
- the rotary slide elements can be driven by a drive unit, wherein a synchronous movement can be achieved via a gear coupling of the two rotary slide elements.
- the drive unit is e.g. an electric pulse clutch in question or an electric motor. Instead of a pulse coupling and an eddy current brake can be used.
- the impulse charger proposed according to the invention is designed in two parts, whereby two smaller units for installation in a charge air duct in the intake tract of an internal combustion engine can be achieved.
- the two rotary valve elements which each form a compact unit and interact with each other, each have a considerably lower mass moment of inertia, compared to the above-mentioned roller slide, which is designed as a cylinder drilled transversely.
- the proposed solution according to the invention has the further advantage that in the ⁇ ff ⁇ tion position of the two cooperating rotary valve elements no har ⁇ ter stop on the wall of the charge air supply occurs, whereby mechanical Ver ⁇ wear is significantly reduced, in turn, the stability of the present invention proposed impulse charger considerably elevated. Further occurs in the closed position, ie the complete closing of the charge air through the two juxtaposed rotary valve elements so no hard stop, but the two coupled rotary slide elements on reaching their closed position überein ⁇ other or take in their closing the charge air supply position a position with overlap. This can be achieved, for example, by displacing the axes of rotation about which the two rotary valve elements coupled to one another are moved.
- the proposed solution according to the invention can be combined with different drive concepts.
- an oscillating armature To drive the two rotary valve elements coupled to each other, an oscillating armature, the above-mentioned electrical impulse coupling or other drive concepts can be used, wherein the coupling of the two rotary slide elements via a transmission, regardless of the drive takes place.
- the drive is, for example, an electric motor to which a rotary oscillating armature is assigned.
- the rotary armature is biased between two springs, so that the Drehschie ⁇ berimplantation can swing back spring assisted.
- a further advantage of the impulse charger proposed according to the invention is that with this cylinder individual filling control of the individual cylinders of the internal combustion engine as well as an improvement of the filling dynamics can be achieved compared to a conventionally arranged throttle device.

- pockets 32 are formed, in which a first rotary valve element 30 and a second rotary valve element 31 can be moved. 2, the first rotary valve element 30 and the second rotary valve element 31 are in their closed position 41.
- the first and the second rotary valve elements 30, 31 each have webs 43, 44, at which at right angles - in the illustration according to FIG ⁇ represents - 41 closing surfaces are formed in the closed position. These are curved so that particles contained in the charge air flow 48 do not accumulate on the surfaces closing off the charge air supply 9, but instead slide past them.
- the first rotary valve element 30 and the second rotary valve element 31 are rotatable about Dreh ⁇ axes 38 and 39 and in the embodiment according to Figure 2 via mitein ⁇ other meshing tooth segments 36, 37 mechanically coupled together.
- the first axis of rotation 38 and the second axis of rotation 39 are arranged at an offset a to each other, which allows overlapping of the facing ends of the first rotary valve element 30 and the second rotary valve element 31 in its closed position 41 and a hard stop of the two rotary valve elements 30, 31st avoid each other.
- the two rotary valve elements 30 and 31 are arranged symmetrically to the axis of symmetry 33 of the charge air supply 9.
- the curved surfaces extending at right angles to the webs 43 and 44 have an inner rotary valve surface 46 and an outer rotary valve surface 45, respectively.

- the closed position 41 In the closed position 41, however, the closed position, which is curved at right angles to the webs 43 and 44, still dives into the pockets 32 of the channel wall 40.
- a leakage flow of charge air 48 via the rotary slide element 30, 31 provided in its closed position 41 is not possible.
- FIG. 3 shows the first embodiment variant of the impulse charger proposed in accordance with the invention, shown in FIG. 2, in the open position.
- the two rotary slide elements 30, 31 coupled to one another via the toothed segments 36, 37 are moved into the open position 42 shown in FIG. 3, the outer rotary slide element surfaces designated by reference numeral 45 return to the pockets 32 and release the flow cross-section of the charge conveyor 9.
- the charge air flow 48 flows around the webs 43, 44, so that the flow is hardly obstructed.
- the webs 43, 44 of the two mutually coupled rotary valve elements 30, 31 are on the one hand so downloaded ⁇ sets that the desired mechanical strength is achieved and on the other hand, a minimal minimal impairment of the charging air flowing through the charge air 9 charge air flow 48 is caused. Due to the coupling of the two rotary slide elements 30, 31 via the toothed segments 36, 37 with each other, the drive drives only one of the two rotary slide elements 30, 31 at.
- FIG. 3 shows that, due to the curvature of the surfaces of impulse charger 13 formed perpendicular to webs 43, 44, air-air flow 48 flows past curved internal rotary valve element surface 45, no dead-water regions are formed in which deposits adhere can, so that sets a self-purifying effect of the rotary valve 30, 31 of the invention proposed impulse charger.
- the ⁇ frhungs triggering time is selected so that significantly after the time at which the intake valve 15 of the Verbren ⁇ combustion engine 1 opens, the pulse clutch triggers.
- the triggering time for opening the rotary valve elements 30, 31 of the pulse supercharger 13 is very early, for example already considerably before the time at which the inlet valve 15 opens. This makes it possible to close the rotary valve elements 30, 31 already at a considerably earlier time, before the inlet valve 15 of the internal combustion engine 1 closes. This can be achieved with respect to the throttle losses optimized load control.
- FIGS. 4 and 5 shows a further embodiment variant of the impulse charger proposed according to the invention in the intake tract of a combustion engine.

This is favorable in terms of short switching times and high driving frequencies. Moreover, with the slide elements 51, 52 shown in FIGS. 4 and 5 in the open position 42 or in the closed position 41, a relatively small angle of rotation of ⁇ 45 ° can be achieved, which also represents an advantage in terms of short switching times and higher actuation frequency when actuated of the impulse charger 13 in the charge air supply 9 to the inlet side 25 of the internal combustion engine 1.
- a division of the cylwderindividual filling control of the individual cylinders of a multi-cylinder internal combustion engine then takes place only after the charge air 48 has passed the impulse charger 13.
