Why Are Off-Road Vehicles Not Afraid of Water?

[DeAliyah]

Off-road vehicles have higher air intake and exhaust ports, giving them a certain wading capability. When leaving the factory, off-road vehicles come with a specified wading depth, typically around 500 millimeters. Related details are as follows: Due to their body-on-frame construction, hardcore off-road vehicles generally have a greater wading depth compared to urban SUVs and sedans. However, it is crucial to avoid water levels exceeding the bumper. If water enters the engine's air intake, it can cause severe internal impacts, leading to immediate engine failure. Additionally, when driving through water, do not reduce throttle or stall the engine. If water enters the exhaust pipe, it can be sucked back into the engine due to the engine's suction force, posing a risk of engine damage. Modifications can be made to enhance wading capability. Most modifications start with waterproof sealing of electrical components and connectors, followed by relocating the intake piping and air filter outside the engine bay to raise their position. It should be noted that after installing a raised air intake, the vehicle's power may be somewhat affected, and fuel consumption will increase significantly.
