General description
1. Converter - a device installed in the exhaust system to reduce emissions of harmful substances.
Neutralizers can be of two types:
- A) to reduce carbon monoxide emissions (CO), hydrocarbons (CH);
- b) CO+CH+ nitric oxide NO.
Control
2. To control the correct operation of the neutral!» blockage requires special equipment Contact a workshop.
3. At home, control consists in a visual inspection of the integrity of the neutralizer body and its fastening.
4. The converter may be clogged with deposits. The simplest way to determine the resistance to the flow of gases through the converter is to measure the vacuum at the outlet:
- A) bring the engine to 2000 rpm;
- b) quickly close the throttle.
- V) if the exhaust resistance is normal, the vacuum will quickly decrease by about 2 mm Hg. st from its usual value.
- G) if the vacuum gauge shows a decrease of 5 mm Hg or fluctuates around the vacuum value at the moment the damper closes, the exhaust resistance is increased.
