This work experimentally investigated the effect of fuel temperature on nano-scale particulate matter (PM) from a Direct-Injection Spark-Ignition (DISI) engine. The first part of the investigation focused on the effect of fuel temperature on combustion characteristics and the second part focused on the engine-out particulate matter. This study found that the injection of chilled fuel into the combustion chamber led to higher in-cylinder pressure, longer duration of combustion (DOC), lower PM number and lower Geometric Mean Diameter (GMD) of the PM than the injection of fuel at ambient temperature.
