An Investigation on The Variation of Vehicular Emissions With Ambient Temperature And Humidity In The Tropics
In this study, we proposed an approach for investigating whether vehicular emissions vary with Ambient Temperature and Humidity of the day. The proposal includes mathematical models that can be used to predict the amount of pollutants dispersed into the atmosphere at a particular time of the day. The pollutants include; NOx, CO, CxHy. These pollutants were measured and analyzed during the morning and afternoon periods, using the Exhaust Gas Analyzer and the Digital Thermometer/Hygrometer. The measured and estimated values of these pollutants compared favorably using MATLAB simulations.
The Implications of Importation of Used Vehicles on The Environment
This study investigates the impact of used vehicles on the environment by sampling a number of such vehicles and carrying out exhaust emission measurements using the Exhaust Gas Analyzer. The exhaust emissions (CO, CxHy, NOx, CO2, SO2) were analyzed to ascertain the level of its concentration.
