Abstract
For numerically predicting the mixture formation and combustion processes in premixed compression ignition engines, fuel spray submodels (the authors' modified wave breakup model, etc.), an ignition submodel (Livengood-Wu's model or Schreiber's reduced kinetic model) and a combustion submodel (Reitz's model) were incorporated into the authors' GTT code. The combustion processes in the two types of premixed compression ignition engines (side-injection and central-injection engines) were numerically analyzed using this code. These submodels were validated by comparing the calculated results of heat release rate with experimental ones. The calculated amount of NO production using the extended Zeldovich mechanism nearly agreed with the experimental one.Keywords
