14-year-old cars comply with either China IV or China V emission standards. The hazards of vehicle exhaust include the following two points: 1. Automobile exhaust contains hundreds of different compounds: The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides, etc.; 2. While directly harming human health, exhaust also impacts the environment of human life: Sulfur dioxide in the gas has a strong irritating odor. When it reaches a certain concentration, it can easily lead to acid rain, causing soil and water sources to acidify, affecting the growth of crops and forests.

Which brand of carbon deposit cleaner is good to use?

Carbon deposit cleaners can be chosen from brands such as 3M, BASF, or Chevron. Below is extended information about carbon deposit cleaners: 1. Limitations of cleaners: Engine carbon deposit cleaners do have practical effects, but due to the short duration they remain in the engine for cleaning, combined with the inherent limitations of non-disassembly cleaning methods, their cleaning effectiveness is relatively limited. 2. How to use carbon deposit cleaners: The cleaner is directly added to the fuel tank to mix with the fuel, and then the vehicle is started. The cleaner will enter the combustion chamber along with the fuel, and while it does, it will clean the carbon deposits inside the engine to a certain extent. Due to the heavy workload and time-consuming nature, most 4S shops do not offer disassembly cleaning services.
