Where is the air intake of a sedan located, and what is the typical wading depth?

[McLucia]

The location of the air intake varies among different car models. Some are positioned in front of the engine, while others are at the rear, with variations in both placement and shape. Generally, sedans have a lower wading depth compared to SUVs, typically not exceeding 20 centimeters. Some low-profile designs may even have a limit of 15 centimeters. You can estimate the water level relative to the vehicle's body components to determine if it's safe to proceed. The primary functions of a car's air intake are as follows: 1. To deliver clean, dry, sufficient, and stable air to the engine, meeting its requirements and preventing large particles of dust from entering the combustion chamber, which could cause abnormal wear; 2. To reduce noise and control air intake: Noise not only affects the vehicle but also impacts cabin noise levels, significantly influencing ride comfort.
