Induction module for an internal combustion engine

Abstract

The invention relates to an induction module (1) with integrated exhaust-gas recirculation. The module comprises the following components: a housing (8) which delimits a housing interior (4) and which has a first housing wall (12) with at least one air inlet (9) for conducting fresh air (F) into the housing interior (4) and has a second housing wall (13) with at least one fluid outlet (11); a charge-air cooler (15) which is arranged in the housing interior (4); a mixing chamber (2) which is part of the housing interior (4) and which is delimited by the charge-air cooler (15) and the second housing wall (13); an exhaust line (3) which is arranged in the mixing chamber (2) and in which there is provided at least one exhaust-gas outlet (7) which fluidically communicates with the mixing chamber (2), by which exhaust-gas outlet an exhaust gas (A) flowing through the exhaust line (3) can be introduced into the mixing chamber (2), wherein the exhaust-gas outlet (7) is provided on a side, facing toward the air inlet (9), of the exhaust line (3).

Description

technical field [0001] The invention relates to an air intake module for an internal combustion engine. Background technique [0002] An air intake module for an internal combustion engine serves to draw air from the environment into the combustion chamber of the internal combustion engine. Basically, in order to take into account the fact that installation space is only available in a limited space in a motor vehicle, one or more functional elements of the intake tract of the internal combustion engine can be integrated into such an intake module. The concept is known in which so-called exhaust gas recirculation is integrated into the air intake module. Exhaust gas recirculation is generally used to reduce the pollutants released into the environment by the internal combustion engine during normal operation and is based on the idea of ​​mixing a part of the exhaust gas produced during the combustion process with fresh air brought in by the intake module and reintroduce it...

AI Technical Summary

Problems solved by technology

By the cooling of fresh air supercharged by the exhaust gas associated with a supercharged internal combustion engine and known as "charge air", contamination of the parts exposed to the fluid and of the intercooler occurs, however, in the worst case Partial "clogging" of the intercooler

Also, if the exhaust comes in contact with moisture, it can form aggressive acids that attack the intercooler or other components

Condensed moisture due to cooling below the dew point is contained in exhaust and fresh air, presenting serious corrosion problems at various locations
