I. Inspection and examination of new vehicles
II. Control of vehicles in use1. Mobile examination (visual determination of smoke emission)
1. Trained and certified environmental examiners judge smoke emission of vehicles driving on roads by visual determination
to identify the
vehicles that emit excessive smoke.
Record the plate numbers of vehicles
that cause severe pollution and
write down the time and place of
occurrence. Photos should be taken
to be used as evidence. Input the
plate numbers that have been
recorded and enquire online about
the registration of these vehicles.
Then notify the owners of these
vehicles to bring them to the
stations to be examined.
2. Static examination (instrumental examination and measurement of smoke emission)
Non-load sudden
acceleration test (Methods and
Procedures for Testing Smoke
Emission of Diesel Vehicles)
Advantages: mobile, convenient; it
can be used at road blocks or at
station inspection. Disadvantages:
since the test is conducted while
the vehicle is in neutral mode, it
is impossible to simulate road
driving. Full-load fixed rotation
test (Methods and Procedures for
Testing Smoke Emission of Diesel
Vehicles)
Advantages: Simulation on road
driving can be done. Disadvantages:
It is not mobile, not convenient,
because the cars must be brought to
the stations.
3. Tip-offs
The public can
give, through telephone or the
Internet, the information about
vehicles that emit excessive smoke
to the authorities.
Input the recorded plate numbers to
enquire online about the
registration information of these
vehicles and notify the owners of
these vehicles to bring them to the
stations to be examined.
III. Examination of diesel fuel (amounts of sulfur contained)
IV. Promotion of vehicles with low pollution
