Abstract
Newly designed laboratory measurement system, which reproduces particle number size distributions of both nuclei and accumulation mode particles in exhaust emissions, was developed. It enables continuous measurement of nano particle emissions in the size range between 5 and 1000 nm.
Evaluations of particle number size distributions were conducted for diesel vehicles with a variety of emission aftertreatment devices and for gasoline vehicles with different combustion systems. For diesel vehicles, Diesel Oxidation Catalyst (DOC), urea-Selective Catalytic Reduction (urea-SCR) system and catalyzed Diesel Particulate Filter (DPF) were evaluated. For gasoline vehicles, Lean-burn Direct Injection Spark Ignition (DISI), Stoichiometric DISI and Multi Point Injection (MPI) were evaluated. Japanese latest transient test cycles were used for the evaluation: JE05 mode driving cycle for heavy duty vehicles and JC08 mode driving cycle for light duty vehicles. The results well indicated the particle number size distribution characteristics of each diesel aftertreatment technology and gasoline combustion system.
For fuel properties, impacts of Ethanol (EtOH)-, Ethyl Tertiary Butyl Ether (ETBE)-, Fatty Acid Methyl Ester (FAME)-blend, aromatics content and distillation characteristics were evaluated on particle number size distributions as well.
