System of production of the fulfilled gases of the models equipped with the catalytic converter

System of production of the fulfilled gases of models without the catalytic converter

On cars considered in the real Management the 3-section system of production of the fulfilled gases (see illustrations System of production of the fulfilled gases of the models equipped with the catalytic converter and System of production of the fulfilled gases of models without the catalytic converter) is used. The shown schemes are characteristic for all model range of Citroёn Xantia cars. All sections of a final path are connected among themselves by means of flange joints. For fastening of a reception pipe to a flange of a final collector bolts with nuts are used, tightness of a joint is reached at the expense of the central sealing ring. The spherical form of interfaced surfaces of connection and use of podpruzhinenny washers provide flexibility of a joint and mobility of sections of system of rather final collector (see the left bottom insert on illustrations). For connection of among themselves remained sections special collars with blooming rings (are used see. inserts "and" on illustrations).

On the models equipped with the catalytic converter, assembly of the last is a part of forward section of a final path and is built in in a reception pipe of system of production of the fulfilled gases.

Posting of sections of system it is carried out by means of rubber basic rings.

Diesel models

On diesel models without the catalytic converter the two-section scheme (a reception pipe and final section) can be used. And, in a place of a joint of a reception pipe with the catalytic converter the broad chamber is provided. For the rest the design of system does not differ from considered above applied on petrol engines. On accompanying illustrations components of fixture of a joint of a reception pipe of system of production of the fulfilled gases with a turbokompressor are illustrated.

On the models equipped with the catalytic converter the system consists of three sections: catalytic converter, intermediate pipe and exhaust pipe. For converter fastening to a final collector the flexible joint, providing to system relative freedom of moving is used. Other sections fasten among themselves by means of collars with blooming rings.

On all the length of section of system are suspended to arms on the car bottom by means of rubber rings.

Removal

The system of production of the fulfilled gases can act in film from the car posektsionno. In view of features of provision of a back cross-section beam removal of system assembled possibly only after a detachment from it final section.

To make removal of system or its separate section it is necessary previously поддомкратить the car and to establish it on reliable props. Alternatively the car can be tired out on a platform or a viewing hole.

Reception pipe

Intermediate section with the preliminary exhaust silencer

Final section with the main exhaust silencer

Thermofilter (ы)

For fastening of thermofilters to the bottom of the car bolts and nuts are used various type. Removal of each of screens becomes possible only after dismantle of the corresponding section of system of production of the fulfilled gases. If the screen acts in film only for the purpose of ensuring access to the components located behind it, on some models will weaken only its fixture enough and slightly to lower a plate.
