Abstract:Combustion chamber components (cylinder head-cylinder liner-piston
   assembly-oil film) were treated as a coupled body. Based on the
   three-dimensional numerical simulation of heat transfer of the coupled
   body, a coupled three-dimensional calculation model for the in-cylinder
   working process and the combustion chamber components was built with
   domain decomposition and boundary coupling method, which adopts the
   coupled three-dimensional simulation of in-cylinder working process and
   the combustion chamber components. The simulation was applied in the
   influence investigation of the space non-uniformity in heat transfer
   among combustion chamber components on in-cylinder combustion. The
   results show that the space non-uniformity in heat transfer among the
   combustion chamber components has nearly no effect on combustion at the
   stage of spray. The effect of heat transfer space non-uniformity of
   combustion chamber components enhances at the later stage of combustion.
   Moreover it can be deduced that the effect of heat transfer space
   non-uniformity would enhanced further during exhaust stroke
