Where is the air intake of a sedan engine located?

The air intake of a sedan engine is located either in front of or behind the engine, depending on the vehicle model. The air intake is one of the important components of a vehicle, as oxygen is required for the combustion of vehicle fuel. During operation, the engine draws air from the air intake to mix with fuel for combustion. Related introduction: 1. Intake system: The assembly of parts that directs air or a mixture into the engine cylinders is called the engine intake system. 2. Four-valve type: This intake system consists of a long curved intake pipe and a short straight intake pipe connected to an air chamber, which are respectively connected to two intake valves on the cylinder head. At low and medium engine speeds, the long curved pipe supplies air to the engine, while at high speeds, the short intake pipe also supplies air simultaneously to enhance engine power.
My old sedan has been running for quite some time. The engine air intake is usually located in the area behind the front bumper, near the radiator grille. When you pop the hood, you'll see a plastic box—that's the air filter, connected to an intake tube that leads directly into the engine. It's positioned there because fresh air flows in from the front of the car, reducing turbulence and allowing the engine to breathe more smoothly. I've also noticed that if you don't check it regularly, leaves or dust can accumulate, causing blockages that affect performance—it feels like the car has asthma. A simple fix is to clean it periodically, either by blowing it out with compressed air or disassembling and wiping it down. The intake is typically placed in the lower front section of the car to take advantage of airflow for cooling during high-speed driving.
