Automotive carbon filling refers to the process of filling a vehicle with activated carbon, which is specifically developed by activated carbon manufacturers to address harmful gases inside the car. It effectively adsorbs these harmful gases. The principle and function of carbon filling are as follows: Principle of Carbon Filling: High-tech methods involve loading nano-photocatalysts onto the inner walls of micropores, which can decompose harmful gases adsorbed by the carbon under light conditions, enabling regeneration and reuse. High-quality porous coconut shell activated carbon with a large specific surface area and strong adsorption capacity is used to effectively remove harmful gases such as formaldehyde, benzene, ammonia, and TVOC. Function of Carbon Filling: It provides strong inorganic antibacterial effects with long-lasting efficacy, broad-spectrum performance, and safety for use, posing no harm to human health. It can be used to adsorb various harmful organic compounds inside the car, such as formaldehyde, benzene, ammonia, and TVOC, achieving the goal of air purification.

What we car enthusiasts often call 'carbon charging' is actually a method to upgrade the turbo system. It involves replacing the turbocharger's housing with one made of carbon fiber, and some who pursue extreme lightweight even replace the blades. This trick is quite common in racing modifications—carbon fiber turbos are more than half the weight of metal ones, reducing engine burden and significantly improving power response during acceleration. However, it's really unnecessary for regular family cars; the modification cost alone could buy a good set of tires. Moreover, carbon charging demands extremely high installation precision—poor sealing can lead to turbo pressure leaks, potentially leaving your car stranded. Last time, someone in the car group tried DIY, only for the carbon shell to deform from heat and crack, wasting thousands of dollars.

Veteran mechanics usually avoid using fancy terms like 'carbon charging.' In our maintenance workshop, hearing about 'carbon charging' is almost always a scam. Some roadside stalls claim they can clean engine carbon deposits by flushing with high-pressure chemicals, boasting about restoring engine power. However, such aggressive treatments can corrode cast iron engine blocks, and we've seen several cases of oil seal damage. For genuine carbon cleaning, older cars are better off using fuel additives for gradual treatment, while newer cars benefit most from regular highway driving. Some shops even pass off touch-up paint as ceramic coating, claiming to 'charge the paint with a carbon-crystal layer'—sounds absurd. For paint care, sticking to waxing or proper coating is far more reliable. These flashy new terms are just gimmicks to fool the unwary.

From a materials science perspective, carbon filling is essentially a carbon fiber repair technique. For example, when a carbon fiber hood gets scratched, epoxy resin mixed with chopped carbon fibers is used to fill the scratches. After hardening and sanding, the strength is restored. This method is commonly used for emergency repairs in motorsports—F1 pit crews can patch holes in front wings in just thirty seconds. There's also carbon filling technology for worn carbon-ceramic brake discs on civilian vehicles, though the cost is often comparable to replacing new brake pads. Last time I helped a friend repair a carbon fiber bicycle frame, we used prepreg material to fill cracks. After hot pressing and curing, it ended up stronger than the original factory condition.
