Abstract
Engine operation is improved by means of detergent additives. An additive comprising, or obtainable by admixing, A or B or both wherein: A is a metal-containing detergent, and B is a non metal-containing detergent, is used in an internal combustion engine lubricated by means of a separate lubricating oil system, to enhance the properties of the lubricating oil of the engine through entrainment therein the combustion chamber during operation of the engine.
Claims10
The use of an additive comprising, or obtainable by admixing, A or B or both wherein:
- A is a metal-containing detergent, and
- B is a non metal-containing detergent,
- in an internal combustion engine lubricated by means of a separate lubricating oil system, to enhance the properties of the lubricating oil of the engine through entrainment therein in the combustion chamber during operation of the engine.
The use of any preceding claim wherein the additive is preferentially absorbed into the lubricating oil lining the combustion chamber.
The use of any preceding claim wherein the additive enhances the viscosity characteristics of the lubricating oil upon entrainment therein, reducing the oil consumption of the engine.
The use of the preceding claims wherein the engine is a diesel engine.
The use of any preceding claim wherein component A is a calcium-containing detergent.
The use of any preceding claim wherein component B is a polyisobutylene succinimide.
