What is the function of the engine exhaust system?

[GabrielleFitz]

Engine exhaust system function: Collects exhaust gases from each engine cylinder, reduces exhaust noise, eliminates flames and sparks from the exhaust, safely discharges exhaust gases into the atmosphere, and controls the emission of harmful substances in the exhaust. The engine exhaust system refers to the system that collects and discharges exhaust gases, consisting of exhaust manifolds, exhaust pipes, catalytic converters, exhaust temperature sensors, automobile mufflers, and exhaust tailpipes. Working principle of the exhaust system: After the exhaust gases from the engine cylinders are discharged through the exhaust valves, they are collected by the exhaust manifolds of each cylinder into the main exhaust pipe, purified by the three-way catalytic converter, muffled by the silencer, and then discharged from the exhaust tailpipe out of the vehicle.
