Vol. 21, nr 1

128--139

The subject of this article was the analysis of the current state of legislation regarding the exhaust emissions from two-wheeled vehicles. The regulations and emission limits were analyzed and compared for different areas of the world. Moreover, the review of the legal provisions includes an individual approach to specific categories of two-wheeled vehicles. The study also describes the research and exhaust emission measurement methods from mopeds and motorcycles both under laboratory conditions and in actual operation. The methods were evaluated in the aspect of future emission requirements and trends. In addition, the results of emissivity measurements under actual operating conditions obtained in the Poznań agglomeration with the use of motorcycle units were discussed and analyzed. The values of road emissions of all toxic compounds limited by legislators were compared with emission standards.
