![]() ![]() DPF equipped diesel buses and CNG buses have virtually identical levels of PM mass emissions and particle number emissions. For all regulated and unregulated emissions, both technologies are shown to be comparable. Unregulated emissions evaluated include toxic compounds associated with adverse health effects (carbonyl, PAH, NPAH, benzene) as well as PM particle count and size distribution. ![]() Using previously published data on regulated and unregulated emissions, this paper will compare the environmental performance of current generation transit buses operated on compressed natural gas (CNG) to current generation transit buses operated on ultra low sulfur diesel fuel (ULSD) and incorporating diesel particulate filters (DPF).
