Variation of CO2, HC, NOX Emissions for an EURO III Engine under Urban Traffic Conditions
Authors: ,
Abstract: In the experimental study were controlled CO2, HC and NOx emissions resulted from combustion into the engine which equips the Dacia Logan 1.4 MPI EURO III car. The experimental simulation of running in traffic conditions was performed on the LPS 3000 chassis dynamometer together with the AVL DiCom 4000 gas analyzer in order to measure the pollutant emissions. Different experimental situations in traffic operation were simulated by activating the stand LPS 3000 braking system, maintaining a constant traction F=0N and F=200N. The tests were accomplished in the Road Vehicles Laboratory from University Politehnica of Timi?oara. It was noticed that high CO2 and NOx values were recorded in the fuel rich mixtures areas and high HC values in the poor mixtures area.
