What are the effects of water ingress in a diesel vehicle's air filter?
2 Answers
Water ingress in the air filter can cause the engine to experience poor acceleration, sluggishness, and insufficient fuel supply, necessitating replacement when required. Below is relevant information about the air filter: 1. Air Filter Overview: An air filter, also known as an air filter cartridge, air cleaner, or air element, is a type of filter typically located on the right side of the engine compartment. 2. Types of Air Filters: Air filters can be categorized into several types, including filtration type, centrifugal type, oil bath type, and composite type. Common air filters used in engines include the inertia oil bath air filter, paper dry-type air filter, and polyurethane filter element air cleaner.
Driving a diesel vehicle is most afraid of water entering the air filter, which is much more troublesome than with gasoline cars. Last time, my friend didn't pay attention when driving through a puddle in the rain, and the engine suddenly stalled as if it choked. After towing it to the repair shop and opening it up, they found the connecting rod was bent. Water sucked into the cylinder can't be compressed at all, and when the piston pushes up, it's a hard impact. In the worst case, the entire engine might need a major overhaul. Water accumulation in the intake pipe can also cause the turbo to rust and seize. So, never force your way through standing water—it's best to install a high-mounted snorkel on the intake pipe. Also, avoid spraying high-pressure water directly at the air intake when washing the car, and always dry any water accumulation in the air filter box promptly.
