Abstract Exhaust emissions during a regeneration cycle of Diesel Particulate Filter (DPF) from diesel trucks were measured using chassis dynamometer. The tested trucks were three and all of them meets most recent Japanese exhaust gas regulations. Two of them have DPF and Urea-SCR system and the other have only the DPF for after treatment devices. As for the emissions, Addition to regulated emissions (CO, Non-methane hydrocarbon, NOx, CO2 and PM), solid particles numbers were measured using three particle counters which cut off diameters were 2.5, 10 and 23 nm respectively. VOCs emissions were also monitored simultaneously using proton transfer reaction plus switchable reagent ion mass spectroscopy (PTR + SRI - MS).
