Engine lubrication

The process of applying a lubricant to reduce friction, heat, and wear between moving components within an internal-combustion-engine.

Key Functions and Criticality

  • Friction Reduction: Prevents direct metal-on-metal contact between moving parts.
  • Pressure Maintenance: oil-pressure is the critical mechanism for engine survival; maintaining adequate pressure is the primary factor in preventing catastrophic engine failure.
  • Monitoring: System integrity is signaled through Oil pressure warning lights, which indicate a loss of lubrication efficacy.
