Direct numerical simulation of n-heptane/air auto-ignition with thermal and charge stratifications under partially-premixed charge compression ignition (PCCI) engine related conditions [PDF]
Applied Thermal Engineering, 2016 Abstract Two-dimensional direct numerical simulations (2-D DNS) are used to study auto-ignition of n-heptane/air mixture with charge and temperature stratifications under elevated pressure and temperature conditions relevant to PCCI (Partially-premixed Charge Compression Ignition) engines.

Energy Procedia, 2015 AbstractPremixed charge compression ignition (PCCI) combustion is capable of reducing nitrogen oxides (NOx) and soot emissions simultaneously, while remaining high fuel efficiency. Whereas, PCCI combustion still faces the challenges of the control of ignition timing and the expansion of operating range.
