- Oil Flow Through the Engine:
- The oil pump draws oil from the oil pan (located in the lower part of the engine) and sends it to various critical components.
- Main Bearings: The oil reaches the main bearings of the crankshaft, which converts linear energy into rotational energy.
- Crankshaft: The oil flows through oil holes drilled in the crankshaft itself.
- Rod Bearings: It then moves to the rod bearings.
- Cylinder Head: From there, it travels through an oil line to the cylinder head.
- Camshaft Bearings and Valves: The oil galleries distribute oil to the camshaft bearings and valves.
- Connecting Rod-Bearings: The pistons, rings, and pins receive oil thrown off by the connecting rod-bearings.
- Functions of Engine Oil:
- Reducing Friction: Engine parts move rapidly and closely together. Oil acts as a lubricant, reducing friction and preventing premature wear.
- Cooling: Engines generate high temperatures during operation. Proper lubrication helps dissipate heat and prevents breakdown due to excessive heat.
- Cleaning: Combustion produces soot and contaminants. Lubricants prevent the buildup of deposits in oil passages, ensuring optimal engine performance.
- Additives Enhance Performance:
- Control Acids and Corrosion: Lubricants contain detergents that neutralize acids, preventing rust and corrosion (especially on bearings). Some high-performance oils also include corrosion inhibitors.
- Viscosity Management: Viscosity refers to the “thickness” of the oil. Consistent viscosity ensures the proper functioning of oil pumps and other components.
In summary, engine oil not only lubricates the crankshaft but also contributes to cooling, cleaning, and overall engine health. Remember to use high-quality oil and follow recommended maintenance intervals for optimal performance!
