The Measurement Accuracy of Vehicle Pollutant Gases

Abstract

In this study analyzed the current methods used to measure pollutant gases, that vehicles issue into the atmosphere. The goal is to apply methods that provide precise values of pollution during technical inspection of vehicles in Albania. In beginning theoretical study of pollutant gases arising from exhaust system is performed, where it results that the pollution amount depends on the regimes of speed and engine load. From the analysis of methods it results that the pollution values measured with loaded test mode are two times more accurate than the no loaded test mode. In conclusion, it is proposed that during technical control of vehicles in Albania, it should use the loaded test mode and remote testing mode and become the control of nitrogen oxides, which have important impact for environmental pollution and global warming.
