Cylinder block for internal combustion engine

摘要

A cylinder block, often a siamese cylinder block, for an internal combustion engine having a heat pipe located in each of the common walls between adjacent cylinders where at least one of the ends of each heat pipe extends into the cylinder block coolant passage such that heat emanating from each cylinder flows into an adjacent portion of one or more heat pipes and flows through the pipes by continuous evaporation and condensation of the pipe's working fluid into the engine coolant.
