Study Notes

Components of an exhaust system include an exhaust manifold, oxygen sensor, catalytic converter, muffler/silencer, resonator, and exhaust pipe.
The exhaust manifold combines each cylinder's exhaust into one pipe.
An oxygen sensor measures oxygen in the exhaust to adjust fuel mixture.
A catalytic converter reduces harmful emissions.
Selective Catalytic Reduction (SCR) technology uses ammonia to break down dangerous emissions.
Mufflers/silencers reduce exhaust noise.
Resonators can further reduce engine noise.
Exhaust pipes carry gas out of the tailpipe.
Symptoms of exhaust problems include noises and abnormal emissions.
Different colored smoke emissions can indicate different issues with the engine.
