What does exhaust HC mean?
1 Answers
Exhaust HC refers to hydrocarbons, which are harmful gases produced during the combustion of gasoline and diesel. Automobile exhaust is the waste gas generated during vehicle use, containing hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. While directly endangering human health, automobile exhaust also has profound impacts on the environment of human life. Sulfur dioxide in the exhaust has a strong irritating odor and, when reaching certain concentrations, can easily lead to the occurrence of "acid rain," causing soil and water sources to acidify and affecting the growth of crops and forests.
