Introducing drop-in renewable fuels into the market is the only option to effectively reduce CO2 emission of the existing vehicle fleet in near time. In this study the two EN228 compliant drop-in renewable fuels POSYN and MTO are evaluated on different gasoline engine hardware platforms. The fuel candidates are benchmarked against EN228 market fuels (RON95E10, RON98), reference fuels (EU5cert and EU6cert) and a high quality first fill fuel (ASF). First, the fuels were screened broadly by evaluation of the fuel properties including the Yield Sooting Index (YSI). Second, the fuels are evaluated in stationary engine tests and typical dynamic test cycles (WLTC, RDE) regarding emissions. Finally, the two renewable fuel candidates were analyzed in more detail via spray tests using optical measurement technologies and engine testing on combustion behavior, engine-out emissions and calibration neutrality including different conditions. The functional advantages of the fuels are highlighted. POSYN and MTO show promising results, e.g. PN emissions are significantly reduced, which is attributed to the fuel specific composition. With increasing renewable share and introducing such fuels, both well-to-wheel CO2 and criteria pollutant emissions reduction is possible within in the current vehicle fleet. Hence, lower criteria pollutant emissions and noticeable air quality improvements associated with rollout of new EU6d vehicles equipped with advanced technologies, e.g. gasoline particulate filters (GPF), can be complemented.
