Structure of 2-stroke engine

The engine structure includes fixed parts that hold the engine together, and support to keep the moving parts in alignment. These parts resist the forces due to engine operation. Internal forces due to the engine are fluctuations in torque, combustion gas forces, or guide forces. Therefore, sufficient strength is provided in the transverse direction. An engine structure offers rigidity and strength to:

  • Ensure crankshaft stresses are minimum
  • Main bearings are uniformly loaded to avoid excessive bending stresses
  • Maintain perfect alignment of the piston and running gear
  • Resist fatigue failure

The structural elements are made of plain carbon normalized steel plates with carbon – 0.16% and UTS – 430 to 500N/mm2.
