We focus on the friction loss measurement and reduction of the timing belt guide plates of a fourcylinder
gasoline engine. To minimize the friction loss caused by the dynamic friction of the guide plates during
timing belt motion and improve the efficiency of the internal combustion engine (ICE), we adopt four different
plastic materials in fabricating the guide plates. With controlled engine boundary conditions and operational
modes, an AVL electric dynamometer is used to measure the output of the engine. The results indicate that
selecting polytetrafluoroethylene (PTFE) as the additive in fabricating the guide plates can effectively reduce
the friction loss, so that the output torque and output power of the engine can be improved, thus reducing fuel
consumptions. This work also has positive impact on the efficiency optimization of similar ICEs.
