Identify the 4 strokes using L-Head Engine
Part of Lesson Plan: 4 Stroke (Cycle) Engine Operation
Activity Overview / Details
You have finished reviewing the parts, summarizing the 4 strokes giving the students the foundation to move on to the next part of the lesson. Students will go to their work stations (2 students to a station) taking out their engine that they have started to disassemble (Note- blower housing and cylinder head have to be removed to do this activity) (Note the L-Head disassembly packet I have included will show you where this lesson fits into the dis-assembly process). At their stations one student will rotate the crankshaft counterclockwise as viewed from the PTO side, while the other student gives a play by play description of cause and effect created by the operations of the engine. Students will trade positions and take on the others role.
