The structure and material of crankcase bearing block of engine are introduced in this paper,and the feasibility that whether the fracture splitting technology can be applied to the bearing block is also analyzed. The mechanism of fracture splitting,the major technological process,the major factor of affecting the quality,the performance and the economic benefit analysis are expounded. Furthermore this paper introduces the merits compared with the past complex technological process,which includes fewer manufacturing procedures,lower cost,higher quality,is obviously economic. In the end,the research and application actuality boti here and abroad are introduced,and the importance of R&D in our country is discussed.
