For the economic development of a country increase in transport industry
activity is vital. This will inevitably expose a large portion of urban
population exposed to automobile pollution emission. Hence, there is a
great need of an emission control strategy to minimize the adverse effects
due to pollution by vehicle emission.
In some parts of the world this problem has been addressed by approaches
such as traffic management measures, established emission standards, effective
vehicle inspection and maintenance programmes (I/M programmes), encouraging
public transport, encouraging cleaner fuel and road user charges etc.
Even though some of the above measures have been initiated in Sri Lanka,
vehicle emission standards or effective I/M programme are almost non-existent.
This paper discusses the present situation of vehicle emission in Sri
Lanka and identifies possible measures that could be adopted to control
vehicle emission by changing the vehicle technology standards. An overview
of principles of automobile emission formation, main sources of emissions,
the effects of the fuels used and emission related combustion chemistry
is also presented.
The historical development of motor vehicle emission control technology
and the standards set by the developed nations have been analysed to identify
probable measures to control vehicle emissions in Sri Lanka in the near
future with affordable technology. Vehicle emission estimates for different
I/M measures, fuel types and vehicle growth scenarios are compared to
identify efficient measures in emission control. In estimating vehicle
emissions the guidelines given by the Intergovernmental Panel on Climate
change (IPCC) and emission factors developed to suit the Sri Lankan conditions
have been used.
