Particle emissions from a modern heavy-duty diesel engine as ice nuclei in immersion freezing mode: a laboratory study on fossil and renewable fuels
<p>We studied ice-nucleating abilities of particulate emissions from a modern heavy-duty diesel engine using three different types of fuel. The polydisperse particle emissions were sampled during engine operation and introduced to a continuous-flow diffusion chamber (CFDC) instrument at a cons...

| description | <p>We studied ice-nucleating abilities of particulate
emissions from a modern heavy-duty diesel engine using three different types
of fuel. The polydisperse particle emissions were sampled during engine
operation and introduced to a continuous-flow diffusion chamber (CFDC)
instrument at a constant relative humidity RH<span class="inline-formula"><sub>water</sub>=110</span> %, while
the temperature was ramped between <span class="inline-formula">−4</span>3 and <span class="inline-formula">−32</span> <span class="inline-formula"><sup>∘</sup></span>C (<span class="inline-formula"><i>T</i></span> scan). The
tested fuels were EN 590 compliant low-sulfur fossil diesel, hydrotreated
vegetable oil (HVO), and rapeseed methyl ester (RME); all were tested without
blending. Sampling was carried out at different stages in the engine exhaust
aftertreatment system, with and without simulated atmospheric processing
using an oxidation flow reactor. In addition to ice nucleation experiments,
we used supportive instrumentation to characterize the emitted particles for
their physicochemical properties and presented six parameters. We found that
the studied emissions contained no significant concentrations of ice-nucleating particles likely to be of atmospheric relevance. The substitution
of fossil diesel with renewable fuels, using different emission
aftertreatment systems such as a diesel oxidation catalyst, and
photochemical aging of total exhaust had only minor effect on their
ice-nucleating abilities.</p> |
