Catalytic converter
 | Because getting the catalytic converter in the number of devices that are protected by the warranty before you begin the replacement at his own expense should be made an inspection in the workshop of dealer branch. |
general description The catalytic converter is part of the reduction of emissions, part of the exhaust system and serves to reduce the emission into the atmosphere of toxic components. There are two types of catalytic converters. Common oxidizing type inverter reduces the level of the exhaust gases of hydrocarbon compounds and carbon monoxide (CO). Three-functional catalytic converter, along with hydrocarbons and CO, reduces the level of nitrogen oxides (NO x). Check Diagnostic equipment to check the status of the catalytic converter is expensive and extremely complex to use. In the event of suspected irregularities in the inverter drive away the car for inspection and repair in dealer branch or having at their disposal the appropriate equipment Car workshop. Every time lifting the car with a view to the ground, catalytic converter, check for signs of leakage, corrosion, dents and other damage. Also check the condition of welds / flange bolts fixing the converter in place to sections of the exhaust system. Damaged catalytic converter must be replaced without fail. Although catalytic converters and do not belong to the number of parts coming out of the building units of the car, from time to time there is a blockage of the combustion products. The simplest way to check the patency of the converter is to use the gauge, which is connected to the test nipple for the detection of the effect of blocking the release on the vacuum inlet. | - Open the throttle, bringing the engine speed to a value of 2000 rev / min.
- Quickly release the shutter.
- If the permeability of the converter is not broken, the gauge readings will fall rapidly to a value of not more than 51 mm Hg. Art. or more above the normal value.
- If the gauge does not fix depression by depth of 127 mm Hg. Art. or higher than the normal value or freezes for a moment at the highest point before returning, cross-exhaust system or catalytic converter is broken (by preventing combustion, deformation of the pipe sections or displacement of partitions inside the muffler).
