Lubrication Systems: Types, Components, and Benefits

Last Updated on January 5, 2026 by Admin

The one thing that can compromise an engine’s performance the most is friction. This, combined with the wear and tear that comes with daily operations and time, not only reduces efficiency but also decreases productivity. This is where engine lubrication systems come in. An effective lubrication mechanism is necessary to prevent heat damage and maintain an engine’s operational capabilities for a long time.

What Is a Lubrication System and How Does It Work?

The lubrication system is a mechanism to supply a lubricant, such as oil or grease, to the engine components to reduce friction and prevent heat damage. It also prevents ongoing structural deterioration and rusting. An engine lubrication system ensures smooth daily operations and prevents damage by creating a thin barrier between metal surfaces that minimizes friction damage and keeps the engine working smoothly and properly.

The lubrication system of an engine uses a lubricant (E.g., oil) stored in an oil/grease tank. This lubricant is pushed through the engine system under pressure by a pump. To ensure delivery of clean lubricant, it first passes through a filter to remove any dust or debris. It then enters the engine system and coats all the metal parts with a thin layer and returns to the tank.

Types of Lubrication Systems Used in Machinery

There are several lubrication system types used in machinery, such as:

• Splash System: A splash lubrication system is usually seen in small engines/older machines and works by splashing lubricant onto the machine parts while they are in motion. 
• Pressure System: As the name suggests, this type of lubrication system uses a pump to pass lubricant through an engine, under pressure. It is commonly seen in modern car engines. 
• Combined System: A combined lubrication system uses both splash and pressure mechanisms to pass the lubricant through an engine system. Examples include medium-duty engines. 
• Dry Sump System: Commonly seen in high-performance or racing engines, a sump lubrication system uses oil stored in an external tank to lubricate the engine. 
• Automatic System: Automatic lubrication systems deliver a lubricant to the engine/machinery automatically at regular intervals to maintain performance. This type of system is common in heavy machinery.
  

Key Components of Automatic Lubrication Systems

An automatic grease or oil lubrication system has the following key components. The system includes a storage reservoir for holding the lubricant, along with a lubrication pump that moves the lubricant through the machine to the required points. A controller regulates the time intervals for lubricant delivery, ensuring lubrication occurs at the correct frequency.

In addition, lubricant distribution lines carry the lubricant throughout the system, while injectors or metering valves control the exact quantity delivered to each lubrication point. Sensors are also integrated to monitor lubricant levels, pressure, and flow, helping maintain system reliability. Finally, the machine parts receiving the lubricant, such as bearings, joints, and gears, are kept properly lubricated to reduce friction, wear, and downtime.
