The most important properties of the automotive engine seal are the low friction and the abrasion resistance. In order to strengthen these properties, the two types of seal are developed and analyzed. One seal is made by mixing the PTFE and the glass fiber and the other is made by mixing the PTFE, the glass fiber and the molybdenum. The analysis of the stress and the reaction force are carried out using the shape design of seal, which is mounted on the front part of the automotive engine. We analyzed the maximum stress and the contact weight of PTFE lip part and then made the two types of PTFE seal. Finally, we evaluated the stress concentration and the abrasion resistance through the coefficient of friction and torque and endurance test.

This study analyzed the mechanical characteristics and evaluated their subsequent performance for two types of seals which reinforced characteristics with lower friction and anti-wear functions among the foremost important features in the automotive engine seals; one with the addition of glass fiber to PTFE(Polytetrafluoro ethylene); the other with the addition of self-lubricant molybdenumin addition to the glass fiber. Based on the configuration design of seal installed to the front part in the automotive engine, this study carried out interpretations on the stress and reaction for those two types of oil seals to compare the maximum stress and contact load generated from the seal steel, rubber and PTFE lip. This study also verified the stress concentration and anti-wear performance through the coefficient of friction, torque and durability test by producing two types of PTFE seals actually.
