The establishment of a standardized diagnosis system for marine diesel engine has been prompted by the increasing difficulty of recruiting skilled engineers and the request for automation of ships. Our research aims at establshing a new diagnostic system based on the visible radiation for marine diesel engine in order to reinforce or substitute for the engineer's diagnosis. This paper discuss that the following helpeful diagnostic technique provides some comparative results of a 4-stroke diesel engine on using the normal exhaust valve and the faulty one. The faulty exhaust valve has slits on the edge of its surface which contacts the exhaust port of the cylinder cover. It is proposed to be easily able to recognize of some difference between normal and abnormal conditions of a diesel engine.
