Abstract
An additive is released into an engine lubricant of an internal combustion engine from a component of the internal combustion engine. The component is manufactured from a polymer, and includes the additive integrally mixed with the polymer. The internal combustion engine is assembled such that the component is exposed to the engine lubricant. The additive is released into the engine lubricant over time during contact between the engine lubricant and the component. The additive may include, but is not limited to bis-nonyl-diphenylamine isomers.
Claims16
An internal combustion engine comprising:
- a lubrication system circulating an engine lubricant therethrough;
- and
- an engine component in fluid contact with the lubrication system and exposed to the engine lubricant;
- wherein the engine component is manufactured from a polymer having an integrated additive releasable over time into the engine lubricant during contact between the engine lubricant and the engine component.
A lubrication system comprising:
- a closed loop fluid circuit;
- an engine lubricant circulating through the fluid circuit;
- and
- a polymer component having an integrated additive that is releasable over time into the engine lubricant during contact between the engine lubricant and the polymer component.
A method of introducing an additive into an engine lubricant of an internal combustion engine, the method comprising:
- providing a component of the internal combustion engine that is manufactured from a polymer having the additive integrally mixed with the polymer;
- assembling the internal combustion engine such that the component is exposed to the engine lubricant;
- and
- releasing the additive into the engine lubricant over time during contact between the engine lubricant and the component.
