Abstract
The aim of the paper is to compare CO, HC, NOx, PM and greenhouse gas emissions for different urban buses regarding to the Euro standard. Three buses were tested, two of them covering the range from Euro III to Euro IV emissions standards, and another one meeting the EEV standard. On-board emission measurements in urban buses were conducted in real world driving routes, operated by the Madrid Municipal Transport Company (EMT), in the city of Madrid. Therefore, the paper examines the real-world efficiency of the emission control technologies conducting tests under real-world driving cycles. It also shows a comparison in emissions and fuel consumption regarding to the type of fuel used. The fuels analyzed are diesel and Compressed Natural Gas (CNG). Finally, the test results obtained directly from the on-board measurements were compared with those results obtained from the application of the COPERT model and another model developed by INSIA to estimate the fuel consumption and pollutant emissions generated by the urban bus fleet of Madrid.
