Abstract: For the frequent occurrence of oil leakage after the application of the sequential turbocharger and two-stage turbo-charger ,the influence of turbocharger sealing structure improvement on oil leakage was researched .A self-developed measuring device for oil leakage was introduced ,the influence of oil pressure ,oil temperature and turbocharger speed on oil leakage was measured and analyzed ,and the actual oil leakage for the three sealing structures such as traditional piston ring ,pump wheel and self-designed guiding channel were evaluated .The results show that the pressure difference of the new-typed guiding chan-nel sealing structure is 7 .0 kPa ,increased by 5 .5 kPa comparing with the traditional sealing .
