5.16.1. Features of a design
The fulfilled gases are removed from the engine through a final collector (fig. 5.15)
and a reception pipe 7 (fig. 5.16)
, converter 3, additional 1 and the main 2 (fig. 5.17)

On a reception pipe the sensor 6 (see fig. 5.16
) is established to concentration of oxygen.
The final collector is fixed by nuts on hairpins of a head of the block of cylinders. Between a head of the block of cylinders and a flange of a final collector two metalreinforced laying 1 (fig. 5.18)
|Fig. 5.18. Knots of system of production of the fulfilled gases: 1–sealing laying of a final collector; 2–laying of a flange of converter of the fulfilled gases; 3–final collector; 4–catalytic converter of the fulfilled gases; 5–sealing laying of a reception pipe; 6–collars; 7–reception pipe; 8–sensor of concentration of oxygen; 9–сильфон; 10-pillows of knots of system of production of the fulfilled gases; 11-additional exhaust silencer; 12-main exhaust silencer; 13-connecting pipe
The reception pipe is connected to flanges of a final collector and converter. Flange connections are condensed with the metalreinforced laying 2 and 5. Converter is connected to a reception pipe of the additional exhaust silencer by means of the pipe which has been pressed out by two collars. The exhaust pipe of the additional exhaust silencer is inserted into a reception pipe of the main exhaust silencer, and the place of their connection is pressed out by a collar. Connections of exhaust silencers with pipes not folding. Each of elements of system can be removed separately without dismantle of other elements.
For reduction of transfer of vibrations from the power unit on system of release and a body in a reception pipe it is built in vibrokompensiruyushchiya goffered сильфон 9 in a metal braid.
Elements of system are suspended to a body on six rubber pillows 10, and two pillows and suspension brackets of the reception pipe, two pillows suspension brackets of the main exhaust silencer and two pillows in a back suspension bracket of the main exhaust silencer and a suspension bracket of the main and additional exhaust silencers have a different form.
For protection of the engine, details of a motor compartment and the basis of a body steel thermoscreens over a final collector, thermoscreens 2 (see fig. 5.16
) over converter both the additional exhaust silencer and 3 (see fig. 5.17
) over the main exhaust silencer are established.
The system of production of the fulfilled gases does not demand special service. Rather periodically to check reliability of an inhaling of carving connections and an integrity of pillows of a suspension bracket. In case of damage of elements of system, through corrosion or прогара them replace assembled as exhaust silencers together with pipes represent not folding knots.
Periodically check system of production of the fulfilled gases. At the increased noise level from system of release check its tightness. For this purpose start up the engine and examine all system. Having carried out a hand over places of possible leak, without concerning knots, you will feel at once leakage of gases. If necessary replace the rusted and burned-through knots.
Before repair let's to system of release cool down, as in engine operating time it heats up to high temperature.
The fulfilled gases are poisonous, poisoning with them occurs imperceptibly therefore before engine start-up in garage surely open gate!
