Problems solved by technology

[0007] Although these known devices achieve a good regulation of the exhaust gas recirculation system with a minimum of costs and components, it has been shown that, in particular in low-pressure exhaust gas recirculation systems, in the exhaust gas flow and the air The turbulence generated by the flow mixing has a

Embodiment Construction

[0027] The regulating device according to the invention is formed by a housing 10 which delimits an intake line 12 and on which is formed a connection 14 for an exhaust gas recirculation line 16 . The intake line 12 extends substantially in a straight direction as far as the axial inlet of the compressor housing of the turbocharger, not shown, while the exhaust gas recirculation line 16 enters the intake line substantially perpendicular to the intake line 12 12.

[0028] The housing 10 consists of a substantially tubular first intake housing 18 , the downstream end of which is formed obliquely and at an angle α of approximately 80° relative to the central axis of the intake line 12 . . The inlet housing 18 protrudes into the mixing housing 20 with its downstream end, or is inserted into the mixing housing 20 until the flange 22 abuts, via which the inlet housing 18 is fixed on the mixing housing 20 by means of bolts 24 . housing 20.

[0029]The connection 14 of the exhaust ...

Abstract

The invention relates to a regulating device for an internal combustion engine, having an intake line (12), an exhaust gas recirculation line (16) connected to the intake line (12), wherein the intake line (12) and the exhaust gas recirculation line are formed. The housing (10) of the circulation line (16), the shaft (28) used as the axis of rotation (30), on which the adjustment body (36) is eccentrically supported, the shaft is perpendicular to the intake line ( 12) and the central axis of the exhaust gas recirculation line (16), wherein in the first end position in which the intake line (12) is at least throttled upstream of the connection of the exhaust gas recirculation line (16) The normal vector of the first surface (44) of the regulating body (36) points to the upstream side of the intake line (12); while the regulating body The normal vector of the second surface (50) of (36) points towards the exhaust gas recirculation line (16). The disadvantage is that the introduction of exhaust gas disturbs the flow and leads to increased condensation and increased flow resistance. In order to solve this problem, it is proposed according to the invention to construct guide ribs (52) on the second surface (50), when the exhaust gas recirculation line (16) is opened, the exhaust gas flows along the guide ribs into the intake line ( 12).

Description

technical field [0001] The invention relates to a control device for an internal combustion engine, which has an intake line, an exhaust gas recirculation line leading into the intake line, and a housing in which the intake line and the exhaust gas recirculation are formed. Line, serving as the shaft of the axis of rotation, on which the adjustment body is eccentrically mounted, said shaft being arranged perpendicular to the central axis of the intake line and the exhaust gas recirculation line, wherein in the first In an end position, the normal vector of the first surface of the adjusting body points to the upstream side of the intake line, in the first end position the intake line is at least throttled upstream of the connection of the exhaust gas recirculation line, and In the second end position, the normal vector of the second surface of the adjusting body points towards the exhaust gas recirculation line, in which the exhaust gas recirculation line is closed.
