GENERAL INFORMATION

Catalyst arrangement under the car

The arrangement of the catalyst is specified by shooters.

For reduction of content of harmful substances in exhaust gases on cars the catalyst which reduces the content of harmful substances by their oxidation and turns into harmless oxides of nitrogen, carbon dioxide and water is installed.

Periodically check surfaces of connecting flanges of the catalyst and an exhaust pipe, and also fastening bolts.

The catalyst can be removed together with system of production of exhaust gases as uniform knot.
