The purpose of the course is to provide students with technical aspects of the design, functions and repair of small engines. In addition students will develop troubleshooting skills in the area of small engine repair.
This course is designed to be an introduction to various types of engines and power train systems and how they are harnessed to do work for humans and society. Harnessing this power/energy and some of the basic systems used to accomplish work will be introduced, discussed and manipulated by students. Basic small engines theory and operations as well as systems troubleshooting methods will be covered during this semester.
Small engine repair is an elective, designed for ninth, tenth, eleventh and twelfth grade students who have had no previous experience in small engine and light portable machine.
