Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Diesel particulate filters (DPF) and urea-based selective catalytic reduction (SCR) exhaust after-treatment systems thus have emerged as feasible strategies to meet the 2010 USEPA regulations.
