A regenerator matrix was proposed and developed based on perfectly new concepts. It is a stacked mesh sheet type. Each thin stainless-steel mesh sheet has small rectangle holes and narrow and shallow grooves which connect holes on the sheet surface. These geometrical shapes are designed freely. Two types of the mesh sheet were designed and manufactured for this study. Each matrix was eqquiped with a NS03T engine and the performance was measured by using an engine test stand. The geometry and performance of the mesh sheet matrixes were compared with conventional wire mesh in detail. One of the new matrixes improved the engine output power and total efficiency remarkably. This paper introduces the experimental results of the new matrix.
