Use L-Head engine to go over the 4 strokes
Part of Lesson Plan: 4 Stroke (Cycle) Engine Operation
Activity Overview / Details
Use a single cylinder L-Head engine that has the cylinder head removed exposing the valves. Rotate the crankshaft counterclockwise as viewed by the PTO side of the engine. Demonstrate to the students how to rotate the crankshaft to get the mechanical parts to move paying attention to the following key parts that they can see visually (Piston, Intake Valve, and Exhaust Valve) NOTE- try to locate your self so all students can see. While you are doing this have the power point on and click to each slide as you get to the stroke listed on the slide (Help reinforce what they are seeing).
