摘要：Combustion chamber components(cylinder head-cylinder liner-piston
   assembly-fuel film) were treated as a coupled body.Based on the
   three-dimensional numerical simulation of heat transfer of the coupled
   body,the multi-dimensional simulation computation coupling flow and
   solid on working process and combustion chamber components of internal
   combustion engine was performed using Discrete Transfer Radiation
   Model(DTRM) radiation heat transfer model,zoning solution method and
   boundary coupling method.The simulation was applied to the influence
   investigation of the space non-uniformity in radiation heat transfer
   among combustion chamber components on in-cylinder fuel atomization.The
   results show that the space non-uniformity in radiation heat transfer
   among the combustion chamber components has great influence on fuel
   atomization.The effect of radiation heat transfer space non-uniformity
   of combustion chamber components enhances at the later stage of
   combustion.The effect on fuel atomization was bound to differences in
   combustion,therefore influences temperature of gas in
   cylinder,combustion and exhaust products
