Automotive Q&A

Answer:

The exhaust manifold is the first part of your vehicle’s exhaust system. It is connected to your vehicle’s engine and collects your engine’s emissions. The exhaust manifold receives the air/fuel mixture the cylinders in your engine, whether you have four, six, or eight.

Not only does the exhaust manifold receive all of the burnt engine gases, but also it completely burns any unused or incomplete burnt gases. The manifold also houses the first oxygen sensor in your exhaust system that inspects the amount of oxygen entering the system. It tells the fuel injection system to increase or decrease the amount of oxygen used in the fuel/air mixture that powers the engine.

Basically, the exhaust manifold acts as a funnel and is used to collect all of the engine’s emissions (from however many cylinders your vehicle has). Then once they are in one place and completely burnt, the manifold sends the emissions into the rest of the exhaust system.
