Manufacturing method of flow box for steady flow test of automobile engine

摘要

The present invention relates to a method of manufacturing a flow box for a steady flow experiment of an automobile engine, and the basic concept setting step of the hop port 4 and the combustion chamber 3a, the three-dimensional modeling operation, and the hop port 4 and the combustion chamber 3a. It is possible to obtain high reliability test data by applying various variables because the manufacturing process of the flow box can be shortened and precise manufacturing can be achieved by the numerical control processing step of.
