Abstract
It seems to be difficult to use engines as educational materials in mechanical engineering lab courses because of lack of budget, space, time and instructors. In this paper, some ideas of using engines with small amount of budget, without changing timetables, with small space and only with one instructor are introduced. We have been working on the program for four years, and obtained good educational results. Three items are used to evaluate students' performances; checking preparative works with short exams, checking behaviors on the day of lab courses and checking assignments posted after the lab courses. It is suggested that preparative works are the most important to obtain higher educational results.
