The present invention relates to a device for cooling charge air for an internal combustion engine of a vehicle. The device comprises a plurality of first coolant pipes for conducting a first coolant and a plurality of second coolant pipes for conducting a second coolant, wherein the first coolant pipes and the second coolant pipes extend in a longitudinal extension direction of the device and the plurality of first coolant pipes is arranged adjacent to the plurality of second coolant pipes in a transverse extension direction of the device.

Device for cooling charge air, system for conditioning charge air, and intake module for an internal combustion engine

The invention relates to an intake pipe for an internal combustion engine of a motor vehicle, comprising a housing that defines a charge-air channel and an intercooler having a cooler block, which is arranged in the housing in such a way that the charge air can flow through the cooler block. The cooler block of the intercooler terminates on a side facing the housing with an outer component, preferably a cooling fin, and at least one recess is formed in said outer component of the cooler block, the at least one recess extending at least across part of the length of the cooler block substantially perpendicularly to the charge-air flow direction. Furthermore, at least one projection is provided on an inside face of the housing facing the cooler block of the intercooler, said projection extending at least across part of the inner face of the housing substantially perpendicularly to the charge-air flow direction and engaging at least partially in the at least one recess of the cooler block in a sealing manner.

Intake pipe having an integrated intercooler

A coupling unit having at least one tubular section; a casing; at least one detent ring, which is arranged radially between the casing and the at least one tubular section when the at least one tubular section, is inserted in the casing, wherein the at least one detent ring, the casing, and the at least one tubular section are configured to adapt to one another such that the tubular section is inserted axially into the casing in a first relative rotational position of the tubular section and the casing, wherein the tubular section is secured by the detent ring against axial withdrawal, the casing and tubular section can be rotated relative to one another, and wherein for decoupling purposes, the tubular section can be withdrawn axially from the casing in a second relative rotational position of the casing and the tubular section that differs from the first rotational position.

Coupling unit

The invention relates to a gas filter insert (), particularly an air filter insert for a fresh air system of an internal combustion engine, having a filter body () which extends in its longitudinal direction () in a U-shape around an inner chamber (), and having a connector () which communicates with the inner chamber () and is arranged on the filter body on the open end-face side () thereof. In order to simplify the construction of the filter insert (), the filter body () is sealed transversally to its longitudinal direction (), with an end plate () on at least one end side ().

Gas filter insert

The invention relates to a gas intake zone of a separable gas filter housing which removably accommodates a filter element. The gas intake zone is used as a prefilter and comprises a plurality of axially adjacent, axially impinged cyclone collectors that are provided with respective spin generators in the inlet zones thereof and gas-discharging immersion tubes at the discharge end within annular ducts which are located between the immersion tubes and the respectively associated outer cyclone walls while being used for pre-separating dirt particles separated in an outer radial direction in the individual cyclones by means of centrifugal forces, the immersion tubes being axially dipped into the interior of the cyclone collectors.

An intake air filter () is for an internal combustion engine, especially in a motor vehicle. The filter has a filter housing () having a raw air inlet (), a pure air outlet (), and an annular filter element () which is arranged in the filter housing () and through which air can flow in a radial manner from the outside towards the inside. The filter element has a first end disk () on the axial end thereof, said disk has an opening () by which means the pure air outlet () communicates with the inside () of the annular filter element (). The purpose is to reduce the influence of a secondary air induction on the fresh air supply of the internal combustion engine. To this end, the filter housing () has a secondary air outlet (), on the pure air side, and the annular filter element () has a second end disk () on an axial end opposing the first end disk (). The second end disk has at least one opening () by which the secondary air outlet () communicates with the inside () of the annular filter element ().
