. … Chemical analysis of the emissions shows that SOA is mainly produced via photo-oxidation of aromatic VOCs, present in gasoline, from the exhaust. Finally, we present the first online measurements of aged exhaust showing that SOA formation also produces reactive oxygen species (ROS) with potentially detrimental effects on our lungs.

Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. A practical powertrain system with robust PPCI combustion is needed, including injection, valvetrain, boost, and exhaust subsystems. kWh and FSN 0.1, respectively.
