“…The characterization of the particulates can be performed by observing the particulate size distribution (PSD). It gives information about the formation of particulates and how gasoline particulate filters (GPF) can handle these particulates, due to the filtration efficiency, which depends on the particulate size [34,35]. Another piece of information is the regeneration habit of these GPFs, which depends on different properties such as the soot reactivity of the filtered soot particulates [36,37].…”

The production of CO2-neutral fuels is a key technology to achieve the European Union’s targets of greenhouse gas reduction in the transport sector. For a straightforward application such as drop-in fuel, regenerative gasoline must meet emission requirements without causing significant changes in engine parameters. The objective of this work was to demonstrate the emission reduction potential of fuel from the bioliq® plant by reducing the content of heavy aromatics in the product refinement. For three blends with varying contents of bioliq® fuel, the spray behavior was studied in a pressurized chamber and the particulate and hydrocarbon emissions were investigated using a single-cylinder research engine. With increasing bioliq® fuel content, atomization was degraded by lower flash boiling at low pressure. This effect vanished at higher chamber pressures. Measurements of particulate and hydrocarbon emissions showed significant improvements of 50% to 100% and 10%, respectively, compared to previously investigated bioliq® fuel fractions from 2017. The formation of particulate emissions is virtually unaffected by the blending of bioliq® fuel, due to the absence of heavy aromatics in the refined bioliq® product. Hydrocarbon emissions increased by 20% with higher bioliq® fuel content and late injection timings due to inferior mixture formation as a result of slightly reduced atomization. However, near the optimum injection timing, the hydrocarbon emissions are independent of the bioliq® fuel admixture.
