Which of the following is true about the exhaust system?

The chosen answer accurately describes the flow of exhaust gases in an internal combustion engine system. Exhaust flows begin in the combustion chamber, where fuel and air mix and combust. After combustion occurs, the exhaust gases are expelled through the exhaust valve. From there, they are directed into the exhaust manifold, which collects these gases and directs them towards the next component in the system, which is the catalytic converter.

The catalytic converter plays a crucial role by converting harmful pollutants in the exhaust gases into less harmful emissions, primarily water vapor and carbon dioxide, before the gases continue through the muffler. The muffler functions primarily to reduce noise generated by the exhaust gases, allowing them to exit through the tail pipe in a controlled manner. This explanation provides a comprehensive understanding of how exhaust gas is managed and processed in a vehicle, highlighting the sequential flow through each component.
