Procedure

  1. 1. INTAKE STROKE
  2. 2. COMPRESSION STROKE
  3. 4. EXHAUST STROKE
  4. 1. INTAKE STROKE:
  5. 2. COMPRESSION STROKE:
  6. 3. POWER STROKE: 4, EXHAUST STROKE: Fig. 1 - The 4-Stroke Cycle As the piston moves down, a vacuum occurs in the cylinder. The intake valve has been opened by the intake cam lobe. Atmospheric pressure pushes the air/fuel mixture through the open intake valve into the cylinder above the piston. At the bottom of the stroke the intake valve closes. The exhaust valve stays closed. As the piston moves up with both valves closed, the air/fuel mixture becomes highly compressed in the space left between the top of the piston and the cylinder head. — . Just before the compression stroke ends, the magneto produces a high voltage arc across the spark plug gap igniting the air/fuel mixture. The rapidly burning mixture expands producing very high pressure, pushing the piston downward. As the piston begins to go up, the exhaust cam lobe opens the exhaust valve and the piston pushes out the burned gases. The exhaust valve closes near the top of the stroke, completing the cycle and the intake stroke begins again. IMPORTANT Fill the crankcase with proper oil before starting engine. See that oil level is maintained at the proper level. SEPTEMBER, 1993 1 GENERAL INFORMATION
