6.4. Catalytic converter

GENERAL INFORMATION

The catalytic converter is installed between forward and average sections of the exhaust system and serves for reduction of emission in the atmosphere of carbon dioxide, oxides of nitrogen and uglevorod.
Prevention

The catalytic converter very strongly heats up in operating time. Be accurate not to burn and to cause the fire at the parking in a dry grass, etc.


Hit of not burned down fuel in the converter can cause its overheat and failure.

On models with the catalytic converter it is impossible to use ethylated gasoline.
