CHAPTER OUTLINE NM




 In a simple one-cylinder engine, the reciprocating (up-and-down) motion of the piston is
nm nm nm nm nm nm nm nm nm nm nm nm


changed to usable rotary motion by the connecting rod and crankshaft. A flywheel
nm nm nm nm nm nm nm nm nm nm nm nm nm


gives momentum to the crankshaft between power strokes. Valves control the engine’s

intake and exhaust. (PPT Slide 4)
