The Euro 5 standards, however, introduced a new metric to limit the particulate emissions of diesel engines: the particle number (PN). The PN limits, which only cover solid particles larger than 23 WebNov 10, 2024 · Zare et al. (2016) reported a maximum of 90% both PM and PN reduction with oxygenated fuel. The reduction in PM emissions additionally depends on fuel properties. The previous study revealed the fuel chemical composition is more influenced in PM reduction than fuel viscosity and cetane number (Rahman et al., 2014b ).
