This course, adapted from military curriculum materials for use in vocational and technical education, teaches students to perform a complete engine tune-up using appropriate hand tools, special tools, and testing equipment. Students completing the course will be able to diagnose gasoline-engine performance and perform corrective measures to restore the engine to the level specified by the manufacturer. The course is divided into two units totaling 81 hours of classroom and shop instruction. Unit 1 on introduction and safety precautions contains a 1-hour lesson introducing the course and discussing safety procedures. Unit 2 on gasoline engine tune-up (advanced) contains three lessons covering 80 hours of classroom and shop instruction on fuel systems components, ignition systems components, and crankcase ventilation service and final tune-up. The course contains both teacher and student materials in one document. Instructor materials include an introduction to the course; an outline of instruction; lists of texts, references, training aids, equipment, course materials, and materials to be prepared by the instructor; and a master schedule.
