Internal combustion engine vehicles also generate other types of pollution, including sulfur oxides and hydrocarbons, however, the amounts generated by transportation are small compared to other activities these emissions are directly responsible for many of the air quality problems faced in major urban areas. As 70% of vehicular nitrogen oxides and particulate matter comes from diesel engines, these measures would, in theory, greatly reduce vehicle pollution however, the problem remains that diesel cars emit far more harmful particulate matter than petrol cars older vehicles there is little hope that all older.

However, in a megacity such as beijing, automobile emissions, instead, is considered number one source of pollution to solve the traffic congestion problem and reduce the use of automobiles in the downtown area has undoubtedly become the most effective and economical way to reduce automobile. Vehicles emit many pollutants into the air, including carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, sulfur oxides, and volatile organic compounds these pollutants then combine to form secondary pollutants such as fine particulate matter and ozone while emissions from an individual vehicle may be. “improving fuel economy and emissions control technology on new vehicles and replacing old cars, trucks, and buses would sharply reduce the transportation sector's share of the problem — but have no effect on the rest of the country's air pollution emissions on the other hand, a climate policy would.

The problem of pollution from automobile emissions

The pollutants emitted by an automotive engine during the combustion process are known as vehicle emission mainly 4 components are emitted they are – carbon dioxide (co2), carbon monoxide (co) and nitrogen oxide (no2) and particulate matter or soot (very small particles black in colour emitted.

  • Emissions that are principal pollutants of concern include: hydrocarbons -- a class of burned or partially burned fuel, hydrocarbons are toxins hydrocarbons are a major contributor to smog, which can be a major problem in urban areas prolonged exposure to hydrocarbons contributes to asthma, liver disease, lung disease.
