Service of system of release of the fulfilled gases - the general information

Check of a condition and repair of components of system of release should be made after a sufficient time interval after engine deenergizing when system components have completely cooled down. Besides, working under the car take care of reliability of its fastening in the lifted condition.

The release system consists of a final collector (ов), каталитического the converter, the muffler, final and connecting pipes, arms, подвесов and fixing collars and clips. System components fasten to the bottom of the car by means of arms and rubber подвесов. Wrong installation of any details conducts to occurrence of extraneous noise and the vibrations transferred on a body of the car.

The arm of an exhaust pipe fastens to the bottom of the car by means of rubber подвеса.

The muffler and pipes

For поддерживания components of system of release constantly in a satisfactory condition and for the purpose of prevention of occurrence of noise and vibrations regularly check a condition of its components. Examine components on presence of damages, the deformations, the dispersed seams, holes, ослабшего fixture, signs of excessive corrosion and other defects as a result of which presence there can be a leak of the fulfilled gases and their hit in car salon. The spoilt sections of system of release should not to try be restored - they should be replaced. Do not forget also about condition check каталитического the converter.

If sections of system as a result of corrosion influence do not give in to a partition, for their removal application of the welding equipment can be demanded. The most simple way of the decision of the given problem is the reference behind the help in a car-care centre workshop where sections will be divided by means of gas cutting. However, in case of the constrained monetary circumstances (or for the purpose of self-satisfaction reception) it is possible to try to make removal of defective components independently. For this purpose (if there is no possibility to take advantage of gas cutting) it is possible to dismember system sections with the help ножовки on metal. If there is an access to a source of compressed air and there is a possibility to take advantage of a pneumatic cutting/cutting nozzle, take advantage of it. Do not forget to put on goggles and work in gloves.

At performance of repair of system of release it is necessary to adhere to following elementary rules:

  • Move ahead along system from its end to the beginning.
  • For simplification отдавания fixture preliminary impregnate with its getting oil
  • At installation of components of system necessarily replace linings, подвесы and collars.
  • Carving part of fixture before installation grease with antitaking hermetic.
  • Make sure that between again established components of system and a surface of the bottom of the car there is the sufficient backlash necessary for prevention of damage of internal furnish of salon, rugs and изоляционного a layer as a result of an overheat. Special attention give to quality of installation каталитического the converter and a thermofilter.

The Katalitichesky converter

The Katalitichesky converter during engine work heats up to very heats. Before touching it make sure that it has enough cooled down.


More detailed information on a design and an action principle каталитического the converter is resulted in the Head of System of decrease in toxicity of the fulfilled gases and engine management.

Regularly check a thermofilter on presence of cracks, dents, easings of fastening or fixture loss.

 PERFORMANCE ORDER

  1. Remove a thermofilter and check up каталитический the converter on presence of cracks and other damages.
  2. If каталитический it is necessary to replace the converter, give nuts of fastening of its both flanges, remove rubber support and take the converter from system of release of the fulfilled gases (for removal of the converter from fixing hairpins it is required to push away sections of pipes of system).
  3. Installation make upside-down. Do not forget to replace a lining.
