  • The Role of Cylinder Geometry on Thermo-mechanical Process in I.C. Engines-1 P M V SubbaraoProfessorMechanical Engineering Department

    Geometry is an Universal Solution of All the Issues.

  • The Geometrical Description of Engine Cylinder

  • Selection of Cylinder Geometry

  • The Kinematic Description of Engine Cylinder

  • Geometry of Cylinder : A Primary Signature An engine is described as a square engine when it has equal bore and stroke dimensions, giving a bore/stroke value of exactly 1.By custom, engines that have a bore/stroke ratio of between 0.95 and 1.04 can be considered "square".An engine is described as under-square or long-stroke if its cylinders have a smaller bore than its stroke - giving a ratio value of less than 0.95.An engine is described as over-square or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1.04.
