Conventional car's mirrors are made of a mercury or silver plate. Inasmuch as reflecting the reflection totally, driving at night becomes hard for drivers. In addition, the working environment with erosion and humidity affects the useful life of these mirrors.
The lower surface of cars is exposed to various physical and chemical hazardous effects such as water, sand and gravel throwing, and if not protected, will quickly corrode and damaged.
Car exhaust gases include paraffin, olefins, aromatic compounds, water vapor, carbon monoxide, nitrogen oxides, sulfur oxides, nitrogen, oxygen and carbon dioxide. Catalytic converter is used to reduce the emission of gasoline and diesel cars. A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction).
