Vehicle Pollution

Vehicle Pollution
These reviews policies for the control of mobile source pollution and their potential application in China. The first section of the paper reviews the U.S. experience with mobile source pollution control since regulations were first established in the Clean Air Act of 1970.

Due to the fast growth of vehicles population in the recent 10 years, esp. in large cities, air
pollution brought about by vehicle emission has become increasingly significant. Days and hours
NOx and O3 concentrations exceeding NAAQS increased continuously; most diesel vehicles
smoked much; road dust resuspended by traffic; high concentrations of CO, HC and SO2 along
roadsides. There is a potential threaten of photochemical smog in large cities. Vehicle emission has become the major sources of air pollutants in the large cities.
Technical policies for emission control of gasoline vehicles, motorcycles and diesel vehicles have been made and implemented.

Meet the requirements of advanced vehicle emission control technologies on fuels, promote the sustainable development of automobile industry, as well as improve air quality and protect human health through improvement of vehicle fuel quality.

This appeal procedure relates to Reduced Pollution Tests carried out for first issue or renewal of Reduced Pollution Certificates or for tests carried out to clear Reduced Pollution Rectification Notices. If however you wish to complain against the issue of a Reduced Pollution Rectification Notice (RPC5) you should refer to your local Road Traffic Enforcement Area Office. Information regarding addresses and telephone numbers of the appropriate local office is available at Vehicle and Operator Services Agency main offices or at your local Goods Vehicle Testing Station.

At the appeal test the reasons given for refusal of a Reduced Pollution Certificate will be considered, and an inspection made of the vehicle by an inspecting officer of the Vehicle and Operator Services Agency to determine whether the requirements of the Road Vehicle (Registration and Licensing) Regulations are fully satisfied in respect of the Reduced Pollution requirements in Schedule 2. In order to do this it will be necessary to expose the engine, exhaust system and any other special fitments that enable the vehicle to emit reduced pollution. The person presenting the vehicle for appeal must be able to tilt cabs or remove inspection panels etc as required to enable this examination to be readily carried out, as for the normal
Reduced Pollution Test procedure. Vehicles presented at appeal will be required to undergo a free acceleration smoke opacity meter test and must be in a suitably well maintained condition for this to be carried out. Additionally, vehicles which normally carry dangerous goods must be presented safe for test. The inspecting officer may refuse to carry out an appeal test if the vehicle is not presented in a suitable condition.
