Embodiment Construction

[0029] in the attached figure 1 , reference numeral 1 denotes a partly shown intake system for the combustion air of an internal combustion engine of a motor vehicle with a supply pipe 3 leading into a drum-shaped air filter housing 2 , a cylindrical air filter 4 and the intake duct 5, the intake duct 5 passes through the intake duct 5 of the partition wall 2a to form a combustion air intake duct. According to the arrows shown, the combustion air drawn in by the internal combustion engine flows through the air filter 4 from the supply line 3 to the intake line 5 .

[0030] The intake duct 5 is divided into two segments 5 a , 5 b forming a peripheral annular gap 6 and is arranged in a housing 7 , preferably of cylindrical or annular section, directly attached to the air filter housing 2 .

[0031] The housing 7 is closed to the outside and surrounds the intake duct 5 , so that a defined resonance volume or damping volume 8 is formed. As shown, the cross-sectional area of ​​th...

Abstract

The invention relates to an assembly of an extraction device for auxiliary components, in particular for an air compressor, on a combustion air intake system of an internal combustion engine, downstream of the air filter, but immediately after a measuring device, especially an air quality measuring device Upstream of the sensor, the extraction device for the auxiliary components is connected to the combustion air intake line of the combustion air intake system. In order to avoid erroneous measurements, it is proposed to form and / or arrange an outwardly closed housing (7) forming a resonance volume and / or damping volume (8) on the combustion air intake line (5) for auxiliary components The auxiliary part extraction line (10) of the extraction device opens into the housing (7) at a position spaced from or away from the combustion air intake line (5), wherein the combustion air intake line ( 5) At least one recess (6) leading to the resonance volume and / or damping volume (8) is formed in it.

Description

technical field [0001] The invention relates to an assembly of an extraction device for auxiliary components, in particular an air compressor, on the intake system of an internal combustion engine. Background technique [0002] DE 10 2008 049 806 A1 describes an intake system for an internal combustion engine in a motor vehicle, in which the outward intake line is integrated in the drum-shaped air filter on the clean air side, the outward intake line with A constructively advantageous embodiment also includes an air mass measuring device with a sensor for calculating the quantity of fuel to be supplied, for example according to the principle of hot-film anemometry or according to the principle of ultrasound. [0003] If such an air intake system is connected to auxiliary components that influence the intake air quantity (in particular the air compressor of the compressed air brake system, etc.) The flow conditions at the measuring point must not be adversely affected. Both...
