Bearings are a key element of the crank-piston system in a combustion engine, ensuring its durability, efficiency and operational safety. Their proper maintenance and replacement are essential to maintaining high engine performance and reliability.
Bearing functions:
- Friction reduction: Bearings ensure smooth movement of pistons in cylinders by reducing friction between the crankshaft and connecting rod.
- Crankshaft Protection: Protects the crankshaft from direct contact with the connecting rods, minimizing wear and ensuring long-term durability.
- Noise reduction: Thanks to their design, the bearings absorb vibrations and noise resulting from the movement of the pistons and crankshaft.
- Oil Conduction: The bushings have channels or grooves that allow lubricating oil to flow, which is necessary to lubricate the contact surfaces.
Types of bearings:
- Main (head) bearings: They are installed in the main bearings of the crankshaft, which are mounted in the engine block. They are responsible for the support and stability of the entire crankshaft.
- Connecting rod (sliding) bearings: They are located between the connecting rod and the crankshaft. They provide direct support for the movement of pistons in cylinders.
Construction of bearings:
- Material: They are usually made of high-quality metal, such as a bimetallic or composite steel alloy, that can withstand high loads and wear.
- Contact surfaces: Specially finished bearing surfaces ensure minimal friction and adequate lubrication.
- Oil Channels: The bushings have channels or grooves that allow lubricating oil to flow, ensuring proper lubrication and cooling.
- The importance of bearings for engine performance: Durability: Properly selected and properly installed bearings are crucial to the durability of the engine, ensuring minimum wear and maximum efficiency.
- Safety: By ensuring the proper operation of the crank-piston system, the bearings contribute to the safe operation of the engine.
- Efficiency: By minimizing friction, bearings help increase engine efficiency, which can impact fuel economy and performance.
Maintenance and replacement of bearings:
- Regular Inspection: During routine engine maintenance, the bearings should be regularly inspected for wear, looseness or damage.
- Replacement: If necessary, for example due to high wear or damage, the bearings should be replaced with new ones. This requires the right tool and experience.
- Compliance with standards: When replacing bearings, follow the manufacturer's recommendations for materials, dimensions and technical specifications to ensure proper engine operation.
