Definitions
- the actuating unit has a cylindrical adjusting space, the cylinder axis of which extends transversely to the axes of the inlet openings, that an outer and an inner adjusting element are arranged coaxially in the adjusting space, that the outer adjusting element is formed by a hollow cylinder is, which rests with its outer surface on the cylinder wall of the storage space and the cylinder walls has openings and that the inner actuating element is formed by at least one slide bar, the outer surface of which is formed by a cylindrical surface which rests on the cylindrical inner surface of the outer actuating element.
- FIG. 2 shows a vertical section through an embodiment of an actuating unit, setting for full-load operation at high speed
- Fig. 5 the actuator according to. 2 in a setting for part-load operation at high speeds
- Fig. 6 the actuator according to. 2 with idle operation or channel shutdown
- Fig. 7 the actuator according to. Fig. 2 in another
- FIG. 1 shows a vertical section through a cylinder 1 of a multi-cylinder piston internal combustion engine.
- the cylinder room In the cylinder room
- a piston 3 which is connected to a crankshaft, not shown here, can be moved up and down.
- the cylinder chamber 2 is closed off by a cylinder head 4, in which a gas inlet valve 5 and a gas outlet valve 6 are arranged, through which the openings of a gas inlet channel 7 and a gas outlet channel 8 into the cylinder chamber 2 are evident in accordance with their activation.
- the gas exchange valves 5 and 6 shown here in the closed position are each connected to an actuator (not shown), for example a camshaft, but preferably also a freely variable actuable actuator, for example an electromagnetically or hydraulically actuated valve drive.
- An actuating unit 9 is assigned to the gas inlet duct 7, to which two intake manifolds 10 and 11 with different intake manifold lengths and / or different intake manifold diameters are connected.
- the suction pipe 10 is short and the suction pipe is long.
- the two intake pipes 10 and 11 open into a central air supply duct 12, via which all intake pipes of the cylinders of the piston internal combustion engine are supplied with air and which is provided with an air filter on the inlet side.
- the gas inlet channel 7 is divided into two sub-channels 7.1 and 7.2 with different flow cross-sections.
- the arrangement is such that the two sub-channels are arranged one above the other with respect to the cylinder axis 13, the upper sub-channel 7.1 having the smaller flow cross section.
- the arrangement can also be made so that the two sub-channels, with respect to the cylinder axis 13, run side by side, the sub-channel with the smaller flow cross-section being assigned to the valve opening of the gas inlet valve 5 such that the air flowing in via this sub-channel is tangential in takes place with respect to a circular plane which is aligned perpendicular to the cylinder axis in the cylinder interior.
- FIG. 2 shows a vertical section of an embodiment of the actuating unit 9.
- This essentially consists of a housing 14 which has two inlet openings 10.1 and 11.1 to which the two suction pipes 10 and 11 are connected.
- Corresponding outlet openings 7.3 and 7.4, to which the subchannels 7.1 and 7.2 connect, are arranged on the opposite side of the housing 14.
- the housing 14 has a cylindrical interior 15, in which two adjusting elements 16 and 17 are arranged which can be rotated or pivoted relative to one another.
- the two adjusting elements 16 and 17 are not shown in the usual sectional marking, but the cut surfaces are provided with a corresponding "signature", so that the different
- Intake pipes have the same inlet cross-section.
- the two adjusting elements 16 and 17 are adjusted relative to one another analogously to FIGS. 3 to 7, the corresponding load cases can also be set with this arrangement.
- 10 to 13 are for the embodiment according to. 9 shows different operating positions, corresponding to the operating positions for the embodiment according to FIG. 2.
- Fig. 10 corresponds to the operating position.
- Fig. 3 The operating position according to Fig. 10 corresponds to the operating position.
- Fig. 11 corresponds to the operating position.
- Fig. 4 corresponds to the operating position.
- Fig. 6 and Fig. 13 corresponds to the operating position according to. Fig. 7.
- the arrangement can grm. 9 are modified in such a way that only one control element, for example the control element 16, is arranged in the control unit 9, which covers the subchannels 7.1 and 7.2 accordingly.
- the function of the other control element can then be brought about by a conventional throttle element in at least one of the suction pipes 10, 11.
- Throttle valves 20, 21 and 22 are arranged at least in the subchannel 7.2 and in the intake manifolds 10 and 11 as actuating elements, each with separate actuatable actuators.
- the load cases described above can also be set in a corresponding manner with this arrangement. Compared to the embodiment according to FIGS. 2 and 3, however, the arrangement additionally requires a further actuator with appropriate control.
- sliders can also be provided.
- two guide flaps 23 and 24, which can be pivoted separately from one another, can also be provided as adjusting elements, by means of which the load cases described above can be set in a corresponding position.
