Survey and repair of components of system of production of the fulfilled gases carry out only after their complete cooling.
The system of production of the fulfilled gases provides branch them in the atmosphere, reduction of concentration of polluting substances, decrease in noise of the engine to demanded level at the minimum losses of engine capacity. That the system of production of the fulfilled gases could carry out the functions, it should be in good repair. The condition of system of production of the fulfilled gases influences as well engine capacity and fuel consumption.
The system of production of the fulfilled gases consists of a final collector, a reception exhaust pipe, catalytic converter and exhaust silencers.
Exhaust pipes provide connections among themselves elements of final system.
Exhaust silencers are intended for smoothing of pulsations in a stream of the fulfilled gases and decrease in noise level. Operation of exhaust silencers is based on two physical effects — a resonance and a sound absorption. Usually in exhaust silencers the combination of these effects is used.
Resonant exhaust silencers consist of the chambers of various length connected among themselves by pipes. Distinction in the areas of cross-section sections of pipes and chambers, change of the direction of a stream of the fulfilled gases and existence of resonators together with connecting pipes and chambers provides optimum reduction of noise, especially on low frequencies.
The system of release fastens to the car bottom with use of elastic elements, for vibration reduction from passing of the fulfilled gases.
On the cold engine check a condition of an exhaust system on all its length.
Check pipes and their connections on leaks, corrosion and damage traces. If components of system of release were treated to corrosion action, disconnect them from system of release and replace new. If separation of pipes of system of release is complicated, by means of the autogenous welding device warm up a junction of pipes and separate them.
Check that all arms and elements of a suspension bracket of an exhaust system in a good condition and are evenly tense.
Moving to the parties an exhaust system of the car, check, that it did not concern a car body. Otherwise replace rubber suspension brackets of an exhaust system.
At repair of system of production of the fulfilled gases surely satisfy the following conditions:
– at removal of components of system of release begin works with a back part;
– for simplification of an otvorachivaniye of nuts and bolts of connection of components of system of release, previously impregnate them with the liquid weakening connections;
– at installation it is necessary use new laying, rubber suspension brackets and clips of fastening of system of release;
– before repeated installation of elements of system clear places of their connection by an emery paper of the hermetic and rust remains;
– for simplification of the subsequent otvorachivaniye grease nuts and the bolts, fixing release system, high-temperature paste.
After work on system of production of the fulfilled gases, check that the system is established freely, without tension and that there is a sufficient gap from body elements.
