Regulators for internal combustion engines

Abstract

A regulating device for an internal combustion engine is known with an intake line (12), an exhaust gas recirculation line (16) opening into the intake line, a housing configured with the intake line and the exhaust gas recirculation line (10), the shaft (28) used as the axis of rotation (30), the adjustment body (36) is arranged eccentrically on the shaft, and the shaft is arranged perpendicular to the central axis of the intake pipe and the exhaust gas recirculation pipe, wherein, in In the first end position, the intake line is throttled at least upstream of the connection of the exhaust gas recirculation line, wherein the normal vector of the first surface (44) of the adjusting body (36) faces the upstream side of the intake line, and In the second end position, the exhaust gas recirculation line is closed, wherein the normal vector of the second surface ( 48 ) of the adjusting body ( 36 ) faces the exhaust gas recirculation line. However, this regulating device has the disadvantage that the increased flow resistance due to the channel throttling reduces the power of the subsequent compressor and the internal combustion engine. To solve this problem, it is provided according to the invention that guide ribs (52) are formed on the first surface (44).

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, a shaft serving as the axis of rotation, on which the adjusting body is mounted eccentrically, the 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.

Problems solved by technology

[0007] If the throttle valve and combined exhaust gas recirculation and throttle valve are arranged upstream of the compressor of the turbocharger of the induction system, pressure losses and thus the compressor of the turbocharger and The power loss of the internal combustion engine is then due to the constriction of the available flow cross-section due to the constriction of the available flow cross-section by throttling with the aid of the valves due to the combination of the air flows
