“…U.S. market fuels, although not used in certification testing, require a minimum detergent concentration [42,43]. It is clear that the use of deposit control additives can assist in minimizing PM/PN emissions by controlling intake valve and fuel injector deposits, which hinder fuel-air mixing and thus increase the potential to form PM [44,45]. Additionally, some additives may be carried in a heavy hydrocarbon suspension and not consumed in the combustion process, which could increase PM.…”

“…Furthermore, after minimal carbon deposits accumulation within the engine, the PM was higher than any of the trails with fuel additives on the clean engine. Although outside the scope of this paper, it is important to note that both parts of the study indicate proper control of market fuel additives can aid in minimizing PM [44].…”

Particulate matter (PM) indices-those linking PM emissions from gasoline engines to the composition and properties of the fuel-have been a topic of significant study over the last decade. It has long been known that fuel composition has a significant impact on particulate emissions from gasoline engines. Since gasoline direct injection (GDI) engines have become the market-leading technology, this has become more significant because the evaporative behavior of fuel increases in importance. Several PM indices have been developed to provide metrics describing this behavior and correlating PM emissions. In this article, 16 different PM indices are identified and collected-to the authors' knowledge, all of the indices are available at the time of writing. The indices are reviewed and discussed in the context of the information required to calculate them, as well as their utility. The authors believe that there is a need for indices that provide both a detailed and robust correlation, as well as those that are less sophisticated yet sufficient for specific use cases. Future research is suggested to guide the technical community toward improvements in the indices' methods and equations for both high and low fidelity and high and low time investment.
