A test program aiming at demonstrating state-of-the-art mopeds emissions performance was conducted, including emissions measurements of not only regulated emissions (HC, CO and NOx) but also particulate mass, particle number and non-regulated gaseous emissions. Four commercially available test vehicles were selected to represent a large variety of technologies currently in operation on the street. One additional prototype moped, developed by IVT, was also included in the test program as it is representative of likely future engine technology. In order to evaluate the influence of different driving patterns, the selected two-wheelers were not only operated on the current and proposed future UNECE R47 test cycles, but also on the reduced speed WMTC part 1 cycle, which is the closest match available for moped specifications. Beside currently regulated gaseous emissions, the emissions of particulate matter were also measured using a gravimetric measurement method combined with a particle counter to provide data on the mass of particulate and number of particles.
