Driving Behavior and Emission Results for a Small Size Gasoline Car in Urban Operation 2000-01-2960

A 1.2 l instrumented car, equipped with an on-board acquisition system capable of detecting and recording car speed, gear, engine and catalyst operating parameters, has been tested in designed trips all over Naples urban area with different drivers. Driving cycles statistically representative of car operation under different traffic conditions in urban and expressway trips, have been determined by multivariate statistical analysis of speed and gear. Emission tests have been performed in the laboratory with car on the dynamometer chassis using defined driving cycles and engine/catalyst conditions to define emission factors for this type of car for a wide and significant spectrum of road performance.
