Influences of Different Exhaust Filter Configurations on Emissions of a 2-Stroke Scooter Peugeot TSDI 2011-24-0203
Exhaust emissions measurements of a small 2-S Scooter Peugeot TSDI*), 50cc with different particle filters have been performed in this present work according to the measuring procedures, which were established in the previous research in the Swiss Scooter Network, [1, 2, 3, 4, 5, 6, 7, 8, 9].
The investigated particle filtration materials were supplied from different manufacturers as samples without specifications and they were applied by the research laboratory in a special muffler able to be taken apart.
The investigated scooter represented a modern (2002) 2-stroke technology with direct injection, with oxidation catalyst and with injection of the lube oil to the intake air.
Since there is a special concern about the particle emissions of the small engines, the particle mass and nanoparticle measurements were systematically carried out.
The nanoparticulate emissions were measured by means of SMPS (CPC) and NanoMet*).
The most important results are:
for the 2-S aerosol, which consists mostly of lube oil droplets, the oxidation in the trap is more important than the filtration quality,
with catalytic coated filters the reduction efficiency of total active aerosol surface (DC) is higher than the reduction of particle counts (CPC, SMPS), with uncatalysed filter inversely,
the highest reduction rates were found: for DC 94% and for CPC 81%
there is a little influence of different PF's on the maximum speed (speed limitation 45km/h), but a high influence on the full load power.
The present investigations did not concern the durability of the filtration materials, the continuous regeneration and the deposition of ashes during the real world operation.
