Cold emissive behaviour of motorcycles (original) (raw)

SAE Technical Paper Series, 2007

Abstract

Abstract: Cold start effect is one of the most significant item for real world emissions evaluation: engine and after-treatment system transient behaviour leads to high levels of pollutants, generally exhausted in urban driving mode. In this paper, literature data referred to cold transient are summarized for some motorcycle classes. The main results of an experimental activity, performed to characterize the cold emissive behaviour of a 125 cc 4-stroke Euro 3 motorcycle during different driving cycles, are then presented. Finally, a ...
