Background and Objective: The control of gaseous emissions of vehicles is very important issue due to high rates of car production in Iran and their toxic emissions. In this study, in order to introduce a superior car compatible with environmental standards, the emissions of hydrocarbons, carbon monoxide and carbon dioxide by Peugeot 206, Samand and EL Samand during 2004-2008 were examined. Method:Preliminary data was collected from Vehicle Inspection Centers and statistical analysis of the experimental data. Moreover, the mean data comparison was carried out using Excel software and Duncan’s Multiple Range Test at a 5% (p < 0.05) alpha level. Results: The results showed that Samand and EL Samand significantly produce more hydrocarbon and carbon monoxide pollutants compared to Peugeot 206, while Peugeot 206 provides a greater amount of carbon dioxide. This could be attributed to the different mechanisms of combustion (complete or incomplete) in the vehicles. Moreover, the downward trend in emissions of hydrocarbons and carbon monoxide was observed during 2004-2008 by Peugeot 206 unlike carbon dioxide. Although, the amount of pollutants produced by Samand and EL Samand was declined. Conclusion: Therefore, Peugeot 206 is more appropriate vehicle in terms of environmental standards as compared to Samand and EL Samand cars. Furthermore, Samand in competition with EL Samand produces more pollutants. It is hoped that by systematic survey of the vehicles performance and improvement their quality the gray dust can be wipe out from sky.
