Intended for a 1- or 2-month curriculum in auto mechanics, this student manual on automotive pollution control was developed by a subject matter specialist at an area vocational school and tested in a vocational auto shop. Intended either for use in an integrated curriculum or for use in teaching pollution control as a separate course, these 12 instructional units contain lessons covering the design, functioning, and service procedures for devices used to control crankcase emissions, exhaust emissions, and fuel evaporation in automobiles. For each lesson, a behavioral objective precedes topical reading materials and questions useful for review or assignment purposes. Working diagrams illustrate the text, which includes introductory teaching suggestions. (AG)
