Definitions
- the invention relates to a holder an exhaust gas recirculation line on the motor housing a Internal combustion engine according to the preamble of the claim 1.
- the invention is based on the object to create compact mount, which at optimal Use of the available space easily and inexpensively can be produced, and a time and cost-saving Assembly possible.
- An advantage of the holder according to the invention lies in the fact that by the integration of the support in one Part of the exhaust gas recirculation line the bracket in a very compact Construction can be produced.
- the saving of a separate support also allows for simultaneous Weight reduction a reduction in manufacturing costs the bracket as well as a reduction of the assembly work.
- the component is not only as mentioned above the holder of the exhaust gas recirculation line on the motor housing the internal combustion engine, but in addition the Support of the mixing housing and the suction module.
- the component axially extending Reinforcing ribs on the on the component counteract acting forces.
- the exhaust gas recirculation line 1 is formed in two parts and comprises a first conduit part 5, which by means of a pipe clamp 6 sealingly with a second conduit part 7 is connected.
- the first line part 5 of Exhaust gas recirculation line 1 branches from a near-engine Exhaust pipe 8 from, in a collecting space 9 of an exhaust manifold 10 opens, which via exhaust pipes 11 at an outlet side 3 a of the cylinder head 3 of the Internal combustion engine is flanged.
- the first Line part 5 subsequent second line part 7 is via a flange 12 with a mixing housing 13 in conjunction, which in turn with a Intake line 14 of the internal combustion engine connected is.
- the intake pipe 14 is part of an an inlet side 3b of the cylinder head 3 flanged Suction module 15.
- the suction module 15 extends in the direction of a motor longitudinal axis 23 substantially over the entire length of the cylinder head 3 and in approximately parallel to the direction of a motor vertical axis 24.
- the mixing housing 13 has a first, over an upper side 15a of the suction module 15 protruding Vacuum box 16, which arranged in a mixing housing 13 Exhaust gas recirculation valve controls.
- the mixing housing 13 has terminals 17 for connecting a second, not shown vacuum box, which also arranged in the mixing housing 13 Throttle controls.
- the exhaust gas recirculation line 1 is in its Course over a motor-fixed support 18 on the internal combustion engine held, according to the invention of second line part 7 of the exhaust gas recirculation line. 1 is formed with the support 18 to a component 19.
- the component 19 is preferably formed by a casting and has axially extending stiffening ribs 22 on. In the area of the support 18, the component 19 has a integrally molded mounting flange 20 and is about this flange 20 by means of fastening screws 21 on the cylinder head cover 4 of the internal combustion engine attached.
- the partially illustrated engine will be in Inclined location built in, causing the center of gravity of the intake module 15 in the direction of the engine vertical axis 24, approximately laterally over the cylinder head cover 4 lies. Due to the inclined mounting position of the engine acts on the suction module 15 together with the mixing housing 13 is a moment that the connected to the suction module 15 Counteracts bracket.
- the forming the bracket Component 19 thus serves not only for exhaust gas recirculation, but at the same time to support the Mixed housing 13 and the suction module 15th
