What is the cloth under the car chassis?

Engine plastic guard plate. Extended information is as follows: 1. Prevent sewage from entering the engine compartment during rain or snow. 2. Prevent small hard objects rolled up during driving from hitting the engine. These generally do not have an immediate impact on the engine, but over time, they can still affect the engine. This is why some unscrupulous dealers do not install guard plates—it saves costs and does not cause direct and rapid effects on the car, so it cannot be called a design flaw. Over time, it can be considered normal wear and tear. 3. Protect engine components and various pipelines, preventing damage caused by contact and friction with the ground under harsh conditions. 4. Improve the airflow under the car, reduce wind resistance and noise, thereby improving fuel economy and overall vibration and noise performance.
A few days ago when I drove to the car wash, I noticed a dusty object hanging under the chassis. At first, I really thought it was a piece of cloth. After asking a friend at the repair shop, I learned that this is an engine guard or chassis protective cover, mostly made of reinforced plastic or synthetic materials, not cloth. Its main function is to block road stones and water splashes from puddles while driving, protecting critical components like the engine and transmission from damage. I often drive on rough suburban roads, and sometimes I can hear stones hitting it with a crackling sound. If it weren't for this guard, the oil pan might get scratched and leak. I suggest everyone occasionally squat down to check it during routine car maintenance to ensure it's not loose or cracked. If it's damaged and not replaced in time, rainwater and mud can get in, causing car problems and increasing repair costs. Now, before every trip, I make it a habit to check it—it feels like the car's invisible bodyguard, inconspicuous but vital for protection.
In my daily auto repair work, people often mistake underbody protection panels for mere fabric. These panels are typically made of composite materials like plastic or metal fibers, specifically designed to protect mechanical components. They serve as buffers against stone impacts and road corrosion. During installation, they must fit snugly against the chassis to prevent gaps where sand and mud could infiltrate and affect the cooling system. I've seen numerous cases where stones flung by tires without protection panels shattered oil pipes or engine covers, significantly increasing breakdown risks. It's advisable to check the panels' secure fit during biannual maintenance using a lift, replacing them promptly if cracks appear. Lightweight materials make installation effortless, and this small investment can prevent costly major repairs—well worth it.
