You make survey and repairs of components of system of production of the fulfilled gases only after their full cooling.
The system of production of the fulfilled gases provides branch them in the atmosphere, reduction of concentration of pollutants, reduction of noise of the engine to the required level at the minimum losses of engine capacity. That the system of production of the fulfilled gases could perform the functions, it has to be in good repair. The condition of system of production of the fulfilled gases exerts impact as well on the 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 mufflers.
Exhaust pipes provide connections among themselves of elements of final system.
Mufflers are intended for smoothing of pulsations in a stream of the fulfilled gases and decrease in noise level. Operation of mufflers is based on two physical effects — a resonance and a sound absorption. Usually in mufflers the combination of these effects is used.
Resonant mufflers consist of the cameras of various length connected among themselves by pipes. Distinction in the areas of cross sections of pipes and cameras, change of the direction of a stream of the fulfilled gases and existence of resonators together with connecting pipes and cameras provides optimum reduction of noise, especially at low frequencies.
The system of release fastens to the car bottom with use of elastic elements, for reduction of vibration from passing of the fulfilled gases.
On the cold engine check a condition of the exhaust system on all its length.
Check pipes and their connections for leaks, traces of corrosion and damage. If components of system of release were affected by corrosion, 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 machine warm a junction of pipes and separate them.
Check that all arms and elements of a suspension bracket of the exhaust system in good shape and are evenly tense.
Moving the exhaust system of the car to the parties, check that it did not concern a car body. Otherwise replace rubber suspension brackets of the 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 remains of sealant and a rust;
– for simplification of the subsequent otvorachivaniye grease the nuts and bolts fixing system of release, high-temperature paste.
After work on system of production of the fulfilled gases, check that the system is installed freely, without tension and that there is a sufficient gap from body elements.
