Starting from the assembly process of remanufactured engine, this paper analyzes the main problems existing in the assembly process, briefly describes the types of remanufactured engine assembly, and puts forward the corresponding assembly methods based on the actual assembly situation of remanufactured engine, and takes the remanufactured engine assembly of a certain type as an example to verify that the purpose of reducing the part loss in the assembly of remanufactured parts and improving the assembly accuracy is achieved. The future remanufacturing assembly methods are further prospected.

Operational errors often occur in the engine remanufacturing process, resulting in quality defects in engine remanufacturing, and even some leading to reduced reliability of remanufactured engines. By elaborating the concept and definition of lean error-proofing, the importance and effectiveness of error-proofing techniques are proposed, and the application of lean-based error-proofing techniques in the engine remanufacturing process is described based on PFMEA analysis in conjunction with common problems in the remanufactured engine process of a certain model. It is proved that the application of lean-based error prevention technology in the engine remanufacturing process can effectively prevent the occurrence of operational errors and achieve zero defects in the quality of remanufactured engines.
