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.
