The main components of gasoline are hydrocarbons, which contain only two atoms of carbon and hydrogen. When gasoline explodes and burns, hydrocarbons react chemically with oxygen inhaled in the air. One carbon atom and two oxygen atoms combine to form one carbon dioxide molecule, and two hydrogen atoms and one oxygen atom combine to form one water. molecular. If the inhaled air is insufficient, the oxygen atoms bound to the carbon atoms will
It appears less, so that the carbon oxide will not be completely formed, and a part of carbon monoxide will be formed. In the process of explosive combustion, due to the extremely high temperature, nitrogen atoms in the air will be oxidized to form nitric oxide and nitrogen dioxide. Therefore, the main components of automobile exhaust are carbon monoxide, carbon dioxide, -nitrogen oxide and nitrogen dioxide.
