Motorcycle emissions testing on a chassis dynamometer

The subject of the article is the emission characteristics of a L3e motorcycle in laboratory conditions. For this purpose, gaseous exhaust compounds such as hydrocarbons, nitrogen oxides, carbon monoxide and carbon dioxide were measured and analyzed. The test object was a motorcycle, equipped with an SI engine with a displacement of 0.7 dm3 and a maximum power of 55 kW. The tests were carried out using the PEMS (Portable Emissions Measurement System) AxionR/S+. The exhaust emissions measurement was done in line with the WMTC (World Motorcycles Test Cycle) certification test, dedicated to vehicles in this category. The test consists of three parts, each of them lasts 600 seconds and has a different maximum speed value. The test was performed on a single-roller chassis dynamometer, designed for testing two-wheeled vehicles. The emission results were presented as a function of time, and the final values of road emissions were compared with the emission limits in accordance with the EURO 4 norm.
