Piston Ring End Gap Between

Piston rings are not made fully connected like a bracelet, but one part is cut. This piece makes a piston ring as a bracelet that is lost on one side. The purpose of this is breaking piston rings for piston rings have a gap for expansion at the moment to conduct heat. This gap will be changed to change depending on the size of the cylinder wall expansion due to heat in the engine. Standard gap which is generally at room temperature is 0.2 to 0.5 mm. As not all piston ring gap is the same, depending on the specifications and characteristics of each - each machine.

At the time of the cylinder block in oversized then the gap between the end of the piston ring which is the basis of measurement. The cylinder will dikorter or in oversized to the size of the gap between the end of the piston ring reaches the size of 0.2 to 0.5 mm. When you do the inspection on the cylinder block, the piston ring gap can be used as the basis of examination and measurement to determine whether the cylinder block in korter necessary or not. If the gap between the end of the piston rings exceeds the standard, then it should dikorter cylinder block and pistons and piston rings must be replaced with a larger size.
Gap between the tip of the excessive piston ring will make the engine compression capability will come down, otherwise if the gap between the end of the piston ring is too small will make a curved piston rings when the heat and make the cylinder walls become damaged. Bending piston ring is due to the hot engine, causing expansion of piston rings. Since the end of the piston rings are too narrow, the space for the expansion piston ring becomes less and result in bent piston rings.
