Problems solved by technology

[0023] figure 1 A disadvantage of the shown intake system (101) is that pressure oscillations of integer engine orders (integer engine orders) predominate in the general intake duct (105) and thus at the inlet of the additional line (106), i.e. have a significantly greater sound pressure level; while due to its low sound pressure level, pressure oscillations in half-orders are secondary

Embodiment Construction

[0079] has been explained in connection with the description of the prior art figure 1 .

[0080] figure 2 A first embodiment of an air intake system 1 of an internal combustion engine with four cylinders 2 arranged in-line is shown schematically.

[0081] Each cylinder 2 has two intake ports for supplying fresh air, each of which is adjoined by an intake duct 3, and the intake ducts 3 of the four cylinders 2 merge upstream to form a total intake duct 5, whereby Intake manifold 4 is formed.

[0082] An additional line 6 is provided in which a noise transfer device 7 is arranged. The open end of the additional line 6 , i.e. the opening point 10 , is led into the vehicle interior or into a cavity adjacent to the interior or towards a vehicle wall delimiting the interior, so that the sound pressure leaving the opening point 10 oscillates Either directly into the interior space where it propagates, or excites the wall to perform body-borne sound oscillations, after which the ...

Abstract

The invention relates to an intake system (1) of an explosive motor with at least two cylinders (2). Each cylinder (2) has one air inlet for supplying fresh air. Each air inlet is adjacently connected through an air inlet pipe (3). The intake pipes (3) of at least two cylinders (2) are merged at upstream to form a general intake pipe (5), forming an intake branch pipe (4) and providing an additional pipeline (6). A noise transmission device (7) is disposed in the additional pipeline (6). The additional pipeline (6) is diverged from the intake branch pipe (4) at a position having a certain distance from the general intake pipe (5). The invention also relates to method for operating the intake system (1) of the same type. The intake system (1) of the invention is capable of providing dynamic noise of engine running in a passenger cabin.

Description

technical field [0001] The invention relates to an air intake system for a motor vehicle internal combustion engine having at least two cylinders, [0002] Each cylinder has at least one intake port for supplying fresh air, [0003] each air intake is adjoined by an air intake duct, [0004] The intake ducts of at least two cylinders merge upstream to form a common intake duct, thus forming the intake duct [0005] gas manifold, and [0006] An additional line is provided in which the noise transfer device is arranged. [0007] The invention also relates to a method for operating an air intake system of the type described. Background technique [0008] In the prior art, a motor vehicle internal combustion engine has at least two cylinders and an air intake system. Each cylinder has at least one intake port for supplying fresh air, each intake port is adjoined by an intake duct, the intake ducts of at least two cylinders merge upstream to form a common intake duct, there...
