Abstract

The report describes briefly the production processes for noise and emissions. In general the HC emissions reduce with speed and NOx emissions increase with speed. C and particulates have lowest emission levels at medium speeds. Hard acceleration can significantly increas pollutant emissions. Above 40-50km/h noise increase linearly with speed. Acceleration and braking cause small (1-2dB) increase in noise. Example estimates for noise and emissions are provided for a limited set of cases of steady speeds
