Abstract
A lubricant having boundary layer properties to minimize friction between contacting metal parts under low-speed, high-load conditions. The lubricant is constituted by an oil intermixed with a dispersion of microfine fluorocarbon particles having an extremely low-coefficient of friction, the dispersion being stabilized by a charge-neutralizing agent such as a silane.
Claims7
A modified oil lubricant suitable for a combustion engine provided with an oil filter, said lubricant comprising major amounts of a liquid lubricating oil intermingled with minor amounts of a dispersion of polytetrafluoroethylene particles in the sub-micron range and a charge neutralizing agent stabilizing the dispersion to prevent agglomeration and coagulation of the particles, whereby the lubricant is capable of passing through said oil filter without separation of the particles from the oil.
A method of improving the operation of an internal combustion engine comprising the steps of adding to the normal lubricating oil for the engine a small but effective amount of an aqueous dispersion of polytetrafluoroethylene particles in the sub-micron range and a charge neutralizing agent stabilizing the dispersion to prevent agglomeration and coagulation of the particles, thereby to impart boundary layer lubricating properties to the oil, then reducing the idling speed of the engine below the prescribed level, and leaving the air-fuel mixture for the engine whereby the emission of pollutants from the engine is significantly reduced.
