Abstract: Error-proof design is very important for the assembly and maintenance of diesel engines. It can reduce the problem of wrong assembly caused by design errors from the source, avoid wrong and missed assembly, and improve assembly quality and assembly efficiency. This paper summarized the principles of error-proofing design for diesel engine assembly, and introduced the typical types of parts and error-proofing requirements related to error-proofing requirements in detail. Finally, several cases of error-proofing design of thrust plate were introduced, and the application of error-proofing technology was further explained.
