5.19.1. Features of a design

Fig. 5.24. System of production of the fulfilled gases: 1 – main muffler; 2 – pillows of a suspension bracket of the main and additional mufflers; 3 – sealing ring; 4 – collar; 5 – additional muffler; 6 – laying of a final collector; 7 – a final collector with converter assembled (katkollektor); 8 – laying of a reception pipe of the additional muffler

The fulfilled gases are taken away from the engine through the final collector of 7 (fig. 5.24) integrated with converter (katkollektor), the additional muffler 5 and the main muffler 1.
On a katkollektor 7 two sensors of oxygen are installed: diagnostic and main (managing director).
Between a head of the block of cylinders and a flange of a final collector the sealing metalreinforced laying 6 is established. The reception pipe of the additional muffler 5 is connected through laying 8 to a katkollektor 7, and an exhaust pipe — to a flange of the main muffler 1 by means of the mobile hinge. Between flanges of pipes of the mufflers forming the hinge the toroidal metalgraphitic ring 3 is established, and in flanges internal spherical surfaces are executed.
For reduction of transfer of vibrations from the power unit on system of release and a body in a reception pipe of the additional muffler the vibrocompensating corrugated bellow valve in a metal braid is built in.
Katkollektor 7 is fixed by nuts on hairpins of a head of the block of cylinders and in addition recorded on the engine by an arm.
Elements of system are suspended to a body on four rubber pillows 2.
For protection of the engine and the basis of a body against heating system elements before a katkollektor and over the additional muffler installed steel thermoscreens. Except them in a motor compartment the additional heat-insulating guard protecting the steering mechanism from an overheat (in fig. 5.24 thermoscreens are not shown) is established.

The arrangement of elements of system on the car is shown in fig. 5.25 and 5.26.

The system of production of the fulfilled gases does not demand special service. Rather periodically to check reliability of an inhaling of threaded connections and integrity of pillows of a suspension bracket. In case of damage of elements of system, through corrosion or a progar they are replaced assembled as mufflers together with pipes represent non-demountable knots.

Good advice
Periodically check system of production of the fulfilled gases. At the increased noise level from system of release check its tightness. For this purpose launch the engine and examine all system. Having run a hand over places of possible leak, not concerning knots, you feel leak of gases at once. If necessary replace the rusted and burned through knots.

Preventions
Before repair of system of release let's it cool down as in operating time of the engine it heats up to high temperature.
The fulfilled gases are poisonous, poisoning with them occurs imperceptibly therefore before launch of the engine in a garage surely open gate!

For removal and installation of knots of system it will be required to you: keys "on 10", "on 13", "on 17", passatizh with narrow sponges, the screw-driver with a flat edge.
