| Summary: | This study was carried out to examine the smoke emission level from diesel powered vehicles
plying Malaysian roads and the problems related to the enforcement of the Motor Vehicles (Smoke
and Gas Emission) Rules 1977. The results show that approximately 35% of the lorries examined had
excessive smoke emission compared to 33% for taxis, 16% for buses and mini buses, and 13% for cars.
Further examination£on of the data did not show any relationship between the degree of smoke emission
and parameters such as age and maintainance of the vehicle, or duration since the last mandatory
inspect£on by the RTD. A study of the past records of enforcement carnage out by the DOE showed
that an average of only 52. 7% of the planned exercises were actually carnage out during 1979 to 1983.
This was due to various reasons including manpower and budget problems, equipment, transportation,
and weather. The selection of suitable sites for curb-side enforcement is nearly always hampered
by the need to select locations which would not cause severe traffic problems and hence did not necessarily
match the traffic flow. The main problem faced by the RTD is the lack of space to carry out
inspection of the motor vehicles. The results also give a strong indication that some drivers of diesel
vehicle may adopt underhand tactics such as tempenng with the engine parts or adding volatile
additives into the fuel tanks to achieve short term reductions for smoke emission during the RTD tests. |
