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 internal combustion engine which comprises an intake system in which a reduction in air switching noise is brought about.
- an air guide tube is provided in the container of the intake system, which is fastened on the inlet side of the intake port of the container and projects freely into the container.
- This container ensures distributed charging of the cylinders due to the substantial separation of the connections by the volume of the container.
- the mutual independence of the wave effect in the individual intake pipes of the cylinders leads to a sharper development of the gas resonance vibrations in each individual intake pipe.
- the resonance vibrations (at their resonance frequency) that arise in one of the cylinders are not damped by the vibrations that arise in the container through the individual suction pipes and even when the initial impulses are compensated by the cylinders; because they run in opposite phase.
- the second unfavorable phenomenon is associated with the excitation of the first asymmetrical form of the gas vibrations in the container. Their frequency is regularly close to a natural frequency of the gas vibration in the individual intake manifold, which leads to an intensive sound radiation from the system, especially at the frequencies that correspond to the odd harmonics of the main frequency of the intake process.
- an air guide tube is inserted into the container, which is arranged coaxially to a central axis with the central axis of the container space and is fastened on the inlet side in the intake port of the container. This connects the container to the air supply and air purification system.
- the mouth opening of the air guide tube provided in the container is located in a plane which is arranged perpendicular to the side wall of the container and which is at approximately the same distance from the center axes of the individual intake pipes of the second and third cylinders.
- the free end of the air duct can be partially perforated or have radial flow openings.
- the mouth opening of the air guide tube is in the vicinity of a node (zero crossing) of a first natural gas vibration of the container of the intake system. In this way, even with resonance excitation, transmission of the acoustic is prevented Energy takes place through the air duct in the direction of the inlet mouth and thereby to the environment.
- Fig. 1 is a schematic representation of a container
- FIG. 3 is a diagram showing a first natural gas vibration with nodes (zero crossing)
- Fig. 4 is a sectional view of the container of the intake system with individual intake pipes, air duct and air duct and air cleaning system, and
- Fig. 5 is seen a view of the container of the intake system in the direction of arrow X.
- the internal combustion engine comprises an intake system with a container 1, the interior A of which is connected to a cylinder head Z via individual intake pipes 2, 3, 4 and 5.
- An intake pipe 6 of the container 1 connects an air pipe 7 projecting into the container, which is connected to an air supply system 8 (throttle valve) or an air cleaning system 9 (filter).
- the air guide tube 7 is firmly connected on the inlet side to the intake port 6 of the container 1, the throttle valve 8 being arranged between the free end of the port 6 and the subsequent pipeline 10.
- a filter 9 is provided downstream of the pipeline 10.
- the tube 7 is arranged coaxially to the container 1, ie the center axis 11 of the container 1 corresponds to the center axis of the air guide tube 7.
- the mouth opening 12 of the tube 7 extends approximately in a plane XX which runs perpendicular to a side wall 13 of the container 1 .
- This plane XX is arranged between the middle individual intake pipes 3 and 4 and the orifice 12 is provided at an equal distance a from the central axes 14, 15 of the individual intake pipes 3 and 4 for the second and third cylinders.
- the mouth opening 12 of the air guide tube 7 is preferably arranged in the region of a node 16 (zero crossing) of a first natural gas vibration in the container 1, which can be seen in more detail in FIG. 3 in connection with FIG. 2.
- the plane X-X in turn runs through this node 16.
- the free end of the air guide tube 7 can be perforated and, in addition to the mouth opening 14, can have radial throughflow openings 26 in various configurations. These openings 26 can be distributed over the circumference of the tube or can also be arranged to extend only over certain circumferential regions.
