Optimal Design of Inlet Valve Oil Seal Structure for a Light Diesel Engine
The leakage rate of intake valve oil seal is one of the main factors affecting the carbon deposition of valve.After studying the structure of intake valve oil seal,a low leakage rate intake valve oil seal structure is proposed to solve the problem of carbon deposit.Through the valve oil seal leakage rate test and durability test,and compared with the intake valve rod diameter change and intake valve sink change before and after the test,the results show that the optimized intake valve oil seal can achieve the effect of reducing the valve carbon deposit under the premise of ensuring the valve,seat guide and other related auxiliary wear acceptable.The results can provide reference for the solution of valve carbon deposition.
