TERMINOLOGY OF IC ENGINE

TERMINOLOGY OF IC ENGINE
1.Bore
   The inside diameter of the      cylinder is called bore
2.Stroke
   The linear distance along the    cylinder axisbetween two limiting  position of the piston is called a
 stroke
3.Top dead centre (TDC)
   The top most position of the piston towards cover end side of the cylinder is called Top dead center
4.Bottom dead center(BDC)
   The lowest position of the piston towards the  crank end side of the cylinder is called Bottom dead centre
5. CIEAREANCE VOLUME
    The volume contained in the cylinder above the top of the piston, when the piston is at top dead center is called Cleareance volume
6. COMPRESSION RATIO
  It is the ratio of total cylinder volume to the Cleareance volume
