Advantages and disadvantages of automobile sandstone block

Advantages: The front wheels are blocked from splashing pebbles on the gravel road surface, especially when following cars for a long distance, so as to prevent the hood from being damaged by gravel when driving. Theoretically, gravel blocks can play a role in disturbing the flow when driving at high speed.

Disadvantages: the fender is only a few centimeters lower than the chassis on both sides of the car body to prevent the crushed sand from drying, but when passing through some convex sections, the ground will rub against the fender, especially the fender made of plastic material, which may rub against the paint surface.

Cars don't need sand and stones.

① The most reasonable drag coefficient has been designed before the car leaves the factory. Adding four fenders in the later stage will obviously increase the wind resistance coefficient, which will not only affect the handling of the car, but even increase fuel consumption.

2 cars are durable goods, just to pull the wind, install fenders and reduce the appearance. The chassis damaged by car paint can be repaired, but ugliness lasts a lifetime.

③ The protruding part of the fender reduces the passability of the car, and it is easy to scratch the fender when passing through some bumpy sections.

④ Car owners don't run at high speed all the year round, or it is unnecessary to install fenders on bad sections with sand and dirt in rural areas.
