The main objective of the study was to conduct measurements on powered two-wheelers to improve knowledge about emissive behaviour of this vehicle category on various types of test cycles. The study presents a method to analyse, during different driving cycles on motorcycles, the influence of speed profile on the emission factors, through the basic parameters of elementary kinematic sequences. These sequences were obtained through suitable fragmentation of complex urban driving cycles. The method was applied to evaluate the regulated exhaust emissions (CO, HC, NOX) and to characterize the emissive behaviour of two Euro3 motorcycles (a 250 and a 1000 cm3), tested on a dynamometer bench.

Abstract
The main objective of the study was to conduct measurements on powered two-wheelers to improve knowledge about emissive behaviour of this vehicle category on various types of test cycles. The study presents a method to analyse, during different driving cycles on motorcycles, the influence of speed profile on the emission factors, through the basic parameters of elementary kinematic sequences. These sequences were obtained through suitable fragmentation of complex urban driving cycles. The method was applied to evaluate the regulated exhaust emissions (CO, HC, NOX) and to characterize the emissive behaviour of two Euro3 motorcycles (a 250 and a 1000 cm3), tested on a dynamometer bench.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
