Designed to prepare students to be engine mechanics working on automotive and large stationary diesel engines, this instructor's guide contains eight units arranged from simple to complex to facilitate student learning. Each contains behavioral objectives, a content outline, understandings and teaching approaches necessary to develop the content, including page references for selected textbooks, and review discussion questions and statements. Unit 1 presents an introduction to the parts and functions of the diesel engine, the use of basic hand tools, job safety, and the relationship between this course and perceived occupational goals. Cylinder heads and their function, analysis, removal, cleaning procedure and valve adjustment are the focus of unit 2. Engine removal, disassembly, and cleaning are discussed in unit 3. Engine parts inspection, unit 4, includes inspecting engines for cleanliness, cracks, and serviceability; determining reasons for part failure or wear; listing all parts requiring service; and listing and ordering replacement items. Unit 5 involves the student in engine part repair, reassembly and reinstallation. Engine accessories such as air conditioners, starting systems, fuel filters and others are examined in unit 6. Unit 7 concerns engine diagnosis and tuneup, and unit 8 focuses on injection systems and controls. Also included are a sample final examination, notes on using audiovisual materials and on preparing and using transparencies, a glossary, a directory of diesel engine and equipment manufacturers from which instructional materials are available, and a bibliography including lists of textbooks, reference books, pamphlets and charts, films, filmstrips and slides, film loops, transparencies and transparency masters. An appendix includes safety information, material on metric measurement, conversion charts, and worksheets. (TM)
