Definitions
- the invention relates to an intake manifold for a multi-cylinder internal combustion engine with two rows of cylinders according to the preamble of claim 1.
- Such a suction pipe system is known from the document DE 42 28 334 AI, according to which the intake manifold the two rows of cylinders of the engine respectively associated intake manifolds and switchable and lockable Zuschaltrohre includes, which can be connected per cylinder row of each switching device bar or shut off.
- the connection tubes have a shorter length than the suction tubes and are switched on under operating conditions with increased power requirements, whereby the cylinders a higher intake air quantity can be supplied and accordingly more engine power can be produced.
- Each of the two respective switching devices associated with a row of cylinders comprises a cylindrical support body which extends over the length of the cylinder row and are rotatably mounted on the pivoting flaps, which open or shut off the pipe cross section of each connecting pipe as required.
- This intake manifold is constructed relatively complicated. Each switching device requires a plurality of movable components, which increases the design effort.
- the invention is based on the problem to provide a structurally simple intake manifold for an internal combustion engine with two rows of cylinders that works reliably over a long period of operation.
- the intake manifold according to the invention has two switching devices, which are designed for each of the two rows of cylinders as a shift drum, which is rotatably mounted and guided through all Zuschaltrohre, wherein in the shift drum with each Zuschaltrohr aligned openings are introduced. By a rotation of the shift drum these breakthroughs between a cross-section of each Zuschaltrohres releasing position and a cross-section blocking position are adjusted.
- the connecting pipes open into the suction pipes, wherein the switching rolls are adjacent to the mouth region of the Zuschaltrohre in the suction pipes.
- the dead volume in the region of the mouth of the shut-off Zuschaltrohrs is much lower than in an arrangement of the shift drum adjacent to the inlet opening of the supply schaltrohre or compared to prior art versions with only a single rotary valve for actuating the Zuschaltrohre for the two opposite rows of cylinders of the internal combustion engine. Due to the small dead volume, the vibration charging of the cylinders improves.
- the intake manifold according to the invention basically has two degrees of freedom due to the possibility of turning each shift drum. Nevertheless, it may be appropriate to operate both shift rollers via a common actuating device, whereby a degree of freedom is kinematically coupled. In an alternative embodiment, it may also be advantageous to adjust the two shift rollers via separate control or adjusting devices.
- each switching drum can take over the function of a flow aid for the suction pipes to the cylinders, in which between adjacent openings in each switching roller, which are provided for the Zuschaltrohre, additional Strömungsaus principles traditions are introduced with laterally limiting flow edges in the shift drum and these flow recesses or these flow flanks of the inlet opening of each suction pipe are immediately upstream.
- the flow flanks serve as a quasi-extension of the suction pipe or as deflection support for the combustion air to be supplied and flowing into the inflow opening from the intake manifold. This function can be used both in the locked position and in the release position of the shift drum for the connection tubes.
- Fig. 2 is a representation corresponding to Fig. 1, but with the right shift drum in the open position.
- the Saugrohranläge 1 shown in section in the drawings is intended for a multi-cylinder internal combustion engine having two rows of cylinders, in each of which a plurality of cylinders are arranged in a row one behind the other.
- the Saugrohranläge 1 includes suction tubes 2 and 3, which extend to different sides of the intake manifold and are assigned to the opposite rows of cylinders of the internal combustion engine. About the suction pipes 2 and 3, the cylinders of the opposite rows of cylinders combustion air is supplied.
- Each intake manifold 2, 3 is assigned in each case a Zuschaltrohr 4 or 5, via which additional combustion air can be supplied as needed.
- Each intake pipe 4 and 5 opens into the associated intake manifold 2 and 3. All suction pipes 2 and 3 and all Zuschaltrohre 4 and 5 for the two rows of cylinders branch off from a Ansaugverteiler 10, which extends over the length of the Saugrohrstrom and about the
- FIG. 1 shows the switching drum 6 passing through the connecting tube 4 in its blocking position, in which the opening 9 is not directed in the direction of flow, but rather on the lateral, delimiting walls.
- the shift drum 6 is connected in the release position, in which the opening 9 is aligned with the flow direction through the Zuschaltrohr 4.
- the adjustment between locking position and release position is expediently carried out by a 90 ° rotation of the shift rollers.
- Both shift rollers 6 and 7 are arranged near the mouth region of the Zuschaltrohre in the respective associated suction pipe, which is minimized in the blocking position, the dead volume in the region of the mouth of the shut-off Zuschaltrohrs. Furthermore, both switching rollers are mounted on a central separating web 8, which expediently likewise extends over the length of the suction pipe system 1.
- each of the two shift rollers 6 and 7 alternately has an opening for switching a Zuschaltrohres and a flow recess with lateral flow flanks 13 and 14 as flow support for the suction pipes seen over the alexiale length.
- the flow recess 12 and the laterally delimiting flow flanks 13 and 14 serve as a flow aid for the inflow of the combustion air from the intake manifold 10 into the inflow opening 11 of the intake manifold.
- the flow flanks 13 and 14 extend over a small angle section, wherein the flow flank 13 has a greater length than the opposite flow flank 14.
- a quasi-extension of the intake pipe length is achieved. Even with a required for switching the Zuschaltrohre rotation of the shift drum basically the advantage of improved inflow into the intake manifold is maintained, since even with a 90 ° twisted shift drum, the two flow flanks 13 and 14 approximately in alignment with the walls of the respective associated intake manifold lie.
