Summary:

In light of forthcoming particle number legislation forlight-duty passenger vehicles, time-resolved Particle Mass (PM) andParticle Number (PN) emissions over the New European Drive Cycle(NEDC) are reported for four current vehicle technologies; moderndiesel, with and without a Diesel Particulate Filter (DPF), DirectInjection Spark Ignition (DISI) gasoline and multi-point Port FuelInjection (PFI) gasoline. The PN and PM emissions were ordered(highest to lowest) according to: Non-DPF diesel DISI PFI ~ DPFdiesel.Both the non-DPF diesel and DISI vehicles emitted PN and PMcontinuously over the NEDC. This is in contrast with both the DPFdiesel and PFI vehicles which emitted nearly all their PN and PMduring the first 200 seconds. The PFI result is thought to be aconsequence of cold-start mixture preparation whilst severalpossible explanations are offered for the DPF diesel trend.The DPF diesel vehicle emitted less nucleation mode particulatematter than the other three vehicles and over 4 orders of magnitudeless than the non-DPF diesel vehicle
