What component prevents harmful exhaust from entering the vehicle?

The exhaust system is specifically designed to channel harmful exhaust gases away from the engine and out of the vehicle, thereby preventing them from entering the passenger compartment. It includes components such as the exhaust manifold, catalytic converter, muffler, and exhaust pipes. These parts work together to collect exhaust gases from the engine, reduce pollutants, and diminish noise before expelling them into the atmosphere.

The windshield, while important for visibility and structural integrity, does not serve a role in managing exhaust gases. The braking system is crucial for stopping the vehicle, and the fuel system is responsible for delivering fuel to the engine. Neither of these systems has a function related to the prevention of harmful exhaust from entering the inside of the vehicle. Thus, the efficiency and design of the exhaust system are integral to ensuring a safe and clean environment for vehicle occupants.
