| Abstract: | Aiming at oil leakage and abrasion of valve guide bush in the diesel engine, the valve guide bush with new style sealing structure is developed, on which only sealing groove is machined and seal ring does not need to be installed. Theoretical analysis on the action mechanism of this structure is carried out. Experiments on components and the whole machine prove that the new type sealing structure can not only reduce the amount of the lubricating oil that flows into the inlet and exhaust pipe, but also lighten the abrasions of valve lever and valve guide bush. So this structure can be widely used in practical applications. |
