Embodiment Construction

[0058] now go to figure 1 , shows a schematic diagram of an engine, or engine system 10 , that may be included in a propulsion system of an automobile. Engine 10 may be controlled at least partially by a control system including controller 12 and by input from a vehicle operator (eg, driver) via an input device 16 (eg, an accelerator pedal). The pedal may be coupled to a pedal position sensor (not shown) for generating a proportional pedal position signal (PP) or the like.

[0059]Engine 10 may include multiple combustion chambers 20 (ie, cylinders), which may be arranged in an inline 4 configuration, as illustrated. However, it should be understood that engine 10 may include any number of cylinders in any configuration (eg, V-6, I-6, V-12, opposed 4, etc.).

[0060] Although in figure 1 Not shown, each combustion chamber 20 (ie, cylinder) of engine 10 may include combustion chamber walls with a piston positioned therein. The piston may be coupled to the crankshaft such th...

Abstract

The invention relates to a supercharger with exhaust gas recirculation. An engine, methods and systems are provided for supercharging charge air for internal combustion engines. The engine having an intake, and a blower with at least one impeller in the intake mounted on a rotatable shaft. An EGR line opens into the intake system upstream of the at least one impeller to form a junction point. A flap, pivotable about an axis running transversely with respect to the intake air flow, has: a first position which blocks the intake by way of a front side, and which opens up the EGR line; and a second position to cover the EGR line and open intake system wherein the flap is not planar, and has, at least on the front side thereof, at least one deformation as an unevenness.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102015214324.4 filed on July 29, 2015, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present application relates to supercharged internal combustion engines, systems and methods including a flap at the junction of an exhaust discharge line and an intake line. Background technique [0004] In recent years, there has been a trend towards supercharged engines, wherein the economic importance of said engines for the automotive industry continues to grow continuously. [0005] Supercharging is primarily a method used to increase performance in which the air required for the engine's combustion process is compressed, with the result that a greater mass of air can be fed to each cylinder during each working cycle. In this way, the fuel mass and thus the average pressure can be increased. [00...
