Reducing wear in the engine parts is one of the most improtant themes for study to allow the use of fuel oils of the higher specific gravities and viscosity, and of low combustibility. It could easily be imagined, that huge amount of time and cost are needed to find out optimal combinations from among a great number of conditions through repetitious round of operations conducted for a long period of time.<BR>It order to meet the requirement, the authors had tried to develop a new wear evaluation technique which requies only a short time operation, as a part of the study on the use of degraded fuel oils.<BR>As a result, we have successfully found the method that allows the evaluation of wear rate on cylinder liners and piston rings, which are apt to be affected by the fuel properties, through operations of around 10 hours. The newly developed tecnique has been introduced at the 20th Lecture Meeting, commemorating the 10th anniversary of the organization, and also at the 17th CIMAC Congress. In the present paper, the authors would like to introduce some examples of practical applications of the technique.
