Definitions
- the invention relates to an intake duct according to the preamble of patent claim 1.
- the object of the invention is to design the partition of the intake duct between the duct sections so that the gas flow enters the combustion chamber with less loss.
- the main advantages achieved with the invention are the fact that the partition - in coordination with the other parts of the channel sections - is designed as an optimized flow body through which friction and pressure losses are substantially minimized. This improves the degree of filling of the internal combustion engine cylinders, which has a favorable effect on the torque, power and consumption of this machine.
- a cylinder head 1 of an internal combustion engine (not shown in detail) comprises an intake duct 2, via which a gas flow reaches a combustion chamber 3.
- the gas flow is controlled by two inlet valves 4 (multi-valve technology) arranged at the end of the intake duct 2, which have valve stems 5 and are actuated by means of a camshaft (not shown in more detail).
- Both inlet valves 4 are, seen in the engine longitudinal direction B-B, side by side.
- the intake duct 2 seen in the flow direction 5, is initially a single duct 6 and then opens in front of the valve stems 5 of the inlet valves 4 - also seen in the flow direction S - into two duct sections 8, 9 which are divided by a partition 7 and have a trouser shape.
- the partition wall 7 running between the channel sections 8, 9 is designed as an optimized flow body 10.
- the flow body 10 is provided with a symmetrical, streamlined profile, ie the profile lines 11, 12 are mirror images of a transverse center plane CC of the cylinder head 1.
- the flow body expands continuously from a rounded tip SK s opposite the gas flow over a first body section SK 1 a maximum width SK max .
- the flow body 10 tapers continuously over a second body section SK2 to a reduced width SK red .
- the maximum width SK max of the flow body 10 is at the point of the lowest friction and pressure loss in the gas flow. After all, the reduced width SK red is as small as possible.
- the flow body 10 namely the interrelationships SK s , SK max and SK red in connection with the profile lines 11, 12 are defined empirically and / or computationally taking into account structural conditions and minimal friction and pressure losses.
