The bending deformation of connecting rod
14 The connecting rod bending deformation of the piston cylinder will cause not along the straight line, the effect of the piston ring sealing function properly, resulting in increased oil consumption. In addition, the connecting rod bending deformation will lead to the gap with the connecting rod bearing and piston pin changes, causing premature wear of the connecting rod bearing, so that more oil is thrown into the cylinder wall.
15 piston pin wear or improper location
If the piston pin wear or improper assembly, under pressure to flow to the piston pin oil, will be left to the cylinder wall and piston ring, can not be excessive oil scraping. This not only leads to excessive loss of oil directly, and the formation of carbon deposits will plug the circuit, causing the piston ring stuck.
16 piston pin assembly tight
If the piston pin are arranged at both ends of the tight, under the engine repeated alternating hot and cold working environment, the piston can not be normal expansion and contraction, cause deformation of the piston, and caused the wall scratch, inevitably leads to channeling gas and oil depletion.
