After the fuel-air mixture gets burnt all the poisonous gases left or produced get gathered in the collector. The system transports all the elements left after burning to this part of the construction under high pressure. Then all the poisonous compounds are transported from the collector to the receiver pipe.
There is extremely high temperature in this part of exhaust system. It can reach up to one thousand degrees centigrade.
The exhaust system has three main functions:
- To safely get hot exhaust gas from the engine out the tailpipe
- Treats the exhaust to remove harmful pollutants
- Muffle the engine noise
