Which component filters air before being atomized with fuel?

• A. Venturi
• B. Air Filter
• C. Throttle Plate
• D. Fuel Filter

Answer: (B)

The essential idea is that clean air must be supplied before it’s mixed with fuel. The air filter sits upstream in the air path and removes dust and debris so only clean air reaches the injector or carburetor. This keeps the air-fuel mixture free of particles that could cause wear, clog jets, or harm combustion. After filtration, the air moves toward the mixing point where flow may be shaped by a venturi to help atomize the fuel, while the throttle plate governs how much air enters the engine. The fuel filter, on the other hand, cleans the fuel line, not the air, and the venturi and throttle plate are concerned with airflow mechanics rather than filtering.
