Investigations on car emissions under the urban traffic conditions with the influence on Timişoara air quality

Abstract Poor air quality, a high traffic level and environmental noise as well as traffic congestion and greenhouse gases emissions require establishing measures, necessary to achieve an environmentally-friendly urban habitat. The priority areas of action in order to reduce greenhouse gases emissions are transportation and construction. Implementing sustainable urban transport plans, including specific measures to promote energy-efficient vehicles and to reduce carbon dioxide (CO2) emissions, will contribute to local reduction of greenhouse gases emissions. In order to evaluate the concentrations of car exhausted emissions under the urban traffic conditions in Timisoara, Romania, which have negative effects on the air quality, experimental researches were achieved regarding the traffic simulation with a non-EURO car operating with two fuel types (petrol and LPG). These researches were performed in the Road Vehicles Lab at the University ‘Politehnica’ of Timisoara and aimed a route in Timisoara downtown w...
