Definition

Noun: A pressure-feed lubricating system is a mechanical system for lubricating internal combustion engines. In this system, a pump actively forces oil under pressure into the engine's bearings and other critical moving parts.

Usage

This term is a technical compound noun used specifically in mechanical and automotive engineering contexts to describe a method of engine lubrication. - The modern engine uses a pressure-feed lubricating system to ensure all bearings receive adequate oil. - Compared to a simple splash system, a pressure-feed lubricating system provides more reliable lubrication at high speeds.

Advanced Usage

• The term is often shortened in technical discussions to "pressure lubrication system" or simply "forced lubrication."
• It is frequently contrasted with "splash lubrication system," which relies on oil splashed by moving parts rather than being pumped.

Variants and Related Words

• Pressure lubrication system: A direct synonym.
• Forced-feed lubrication system: An alternative name emphasizing the forced action of the pump.
• Oil pump: The key component that creates the pressure in this system.

Synonyms

• Forced lubrication system
• Force-feed lubricating system

Related Phrases

• Full-pressure lubrication: A phrase emphasizing that oil is delivered under pressure to all necessary points.
  • Most automotive engines use full-pressure lubrication.
