Abstract:Recently
Portable Emission Measurement System (PEMS) is being used to show the real
emission components of diesel engines (and petrol engines) instead of using
test cycles because of their more realistic measurements. Their drawback is
their high price and unavailability. This study investigates the possibility of
transforming a fixed gas analyser that cost approximately RM50,000 into a PEMS.
The project was done through the simulation of a program coded using Python to
imitate the functions of a PEMS as close as possible. In the code, it is
programmed to calculate emission from a diesel-based vehicle, based on the
changes of the Torque and RPM. Simulation of the code uses data from a research
paper reviewed. The difference of the project simulation and the research paper
data is 6.32%. It is concluded there is
a possibility as the code was able to be validated. Keywords: Vehicle gas emissions, air pollution,
