Several intermediate performance objectives and corresponding criterion measures are listed for each of five terminal objectives presented in this curriculum guide for a basic gasoline engine mechanics course at the secondary level. (For the intermediate course guide see CE 010 946.) The materials were developed for a two semester (2 hours daily) course to provide training in the terminology, construction, and function of both two-and four-cycle internal combusion engines. The course includes instruction and practical experience in the areas of safety, care and use of tools and manuals, theory of internal combustion, ignition and electrical systems, fuel systems, and troubleshooting. The titles of the five terminal objective sections are Orientation, Hand Tools, Engine Construction, Ignition, and Fuel System. (This manual and 54 others were developed for various secondary level vocational courses using the System Approach for Education (SAFE) guidelines.) (HD)
