| Abstract | ||||
| A new oil additive is tested to justify its influences on the performance of the Internal Combustion Engines (ICE). This additive belongs to the fluoroplastics group. It contains polytetrafluoroethylene (PTFE), Some forms of which were developed before in USA under the brand names Teflon, Fluon or Hostaflon. Also a high-polymer form of PTFE was used for years in advanced bearing, clutch disk and valve stem packing design in the automotive industry, however its use was limited to components of racing engines. In this research low polymer PTFE is tried as an additive to ICE oils, to produce a self-lubricating coating on the concerned engine components. Tests are carried out to investigate the effects of PTFE on the behavior of ICE. The results reflected an increase of about 9% in the compression pressure, 6% in the oil pressure, 8% in the engine power. The results also showed a decrease in fuel consumption of about 4%, a noticeable reduction in engine noise, no contamination effects and no change in oil viscosity. It is concluded that the PTFE low polymers are deposited on the metal surface of the internal parts of the engine forming a durable slippery coat which significantly reduces the friction, consequently the wear, and improve the tolerances. | ||||
