Applying the multi-zone model in predicting the operating range of HCCI engines
Jia, M.; Xie, M.; Peng, Z.J. (2010-09)In this paper, a multi-zone model is developed to predict the operating range of homogeneous charge compression ignition (HCCI) engines. The boundaries of the operating range were determined by knock (presented by ringing ... -
CFD analysis of VVT/VVA on the gas exchange and fuel-air mixing in a diesel engine
Peng, Z.J.; Jia, M.; Lu, L. (2009-04-01)A three-dimensional simulation was carried out for investigating effects of negative valve overlap (NVO) on gas exchange and fuel-air mixing processes in a diesel homogeneous charge compression ignition (HCCI) engine with ... -
The effect of injection timing and intake valve close timing on performance and emissions of diesel PCCI engine with a full engine cycle CFD simulation
Jia, M.; Xie, M.; Wang, T.; Peng, Z.J. (2011-09-01)A full-cycle computational fluid dynamics (CFD) simulation coupled with detailed chemical kinetics mechanism has been used to investigate the effect of start of injection (SOI) timing and intake valve close (IVC) timing ... -
Full engine cycle CFD investigation of effects of variable intake valve closing on diesel PCCI combustion and emissions
Peng, Z.J.; Jia, M. (2009)A full-cycle three-dimensional computational fluid dynamics (CFD) model coupled with detailed chemical kinetics has been developed to investigate the effect of late intake valve closing (IVC) on combustion and emission ... -
An investigation and evaluation of variable-valve-timing and variable-valve-actuation strategies in a diesel homogeneous charge compression ignition engine using three-dimensional computational fluid dynamics
Peng, Z.J.; Jia, M. (2008-06-01)A three-dimensional computational fluid dynamics modelling was carried out to investigate effects of variable valve timing (VVT) and variable valve actuation (WA) on gas exchange and fuel-air mixing processes in a diesel ... -
Numerical investigation of soot reduction potentials with diesel homogeneous charge compression ignition combustion by an improved phenomenological soot model
Jia, M.; Peng, Z.J.; Xie, M.-Z. (2009-03-01)An improved phenomenological soot model coupled with a reduced n-heptane chemical mechanism was implemented into KIVA-3V code to describe soot formation and oxidation processes in diesel homogeneous charge compression ...
