Benefits of technology

[0007]As a result of this integrated configuration of the exhaust gas recirculation line in a connecting component, the installation space available within the engine compartment is utilized in an optimum manner. A part of the connecting component is preferably in the form of a support element, in particular a support eye. As a result of the integration of a line section of the exhaust gas recirculation line into a connecting component which also includes a support structure in the form of a suspension eye, an additional separate holding device is not needed, as a result of which the manufacturing and assembly costs and assembly time and also the weight o

Example

[0014]Parts which correspond to one another are provided with the same designations in all the figures.

[0015]FIG. 1 shows a holder 1 of a partially integrated exhaust gas recirculation line 2 for an internal combustion engine (not shown).

[0016]The holder 1 is arranged in the form of a connecting component between an engine block (not shown) and a vehicle frame (not shown). In the following text, the holder 1 will be described in detail using the connecting component which is denoted in the following text by the reference numeral 1.

[0017]In order to hold and fasten the holder 1 on the engine block and / or on the vehicle frame, the holder 1 in the exemplary embodiment has two reinforcing elements 3 (also called a support) which are formed as a single piece and are in the form of fastening flanges. The holder 1 is firstly supported on the engine block or vehicle frame via said reinforcing elements 3. Secondly, the holder 1 is fastened via the reinforcing elements 3 by screw- or threaded...

Abstract

In an exhaust gas recirculation line holder of an internal combustion engine wherein a line section of an exhaust gas recirculation line is integrated into the holder which is supported on the engine block and/or the vehicle frame, the holder is provided with a shaped part, in particular a cast part, with the line section of the exhaust gas recirculation line formed therein and a support structure also being formed integrally with the holder so that manufacturing costs, assembly time and assembly expenditure are reduced.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to an exhaust gas recirculation line holder of an internal combustion engine.[0002]An exhaust gas recirculation system is used to reduce nitrogen oxides (NOx) during combustion of fuels in internal combustion engines, for example in Otto or diesel engines, in order to adhere to the stipulated emissions limit values specifically for internal combustion engines.[0003]The exhaust gas recirculation line is usually configured in the form of a connecting pipe extending between an exhaust gas pipe and an intake pipe and is provided with a control valve. Here, fresh air which is sucked in by the intake pipe is mixed with exhaust gas which is recirculated from the exhaust gas pipe. As a result, the calorific value of a fuel / combustion gas mixture is reduced and the temperature which is required for the formation of nitrogen oxides is no longer reached in the combustion chamber.[0004]DE 197 01 873 C1 discloses a holding device for an exha...
