The crankshaft for these Mitsubishi diesel engines is typically made from high-quality forged steel.
This material is chosen for its exceptional strength, resistance to wear, and ability to withstand the high stresses and loads associated with heavy machinery operation.
Design:
Mitsubishi has designed the crankshaft for the S4F, S4K, and S6K engines with precision engineering to ensure optimal balance and minimal vibrations. A well-balanced crankshaft is crucial for the engine's smooth and efficient operation.
Counterweights:
Crankshafts are equipped with counterweights to balance the dynamic forces generated by the reciprocating motion of the pistons. This balancing reduces vibrations, enhances engine performance, and extends the lifespan of the engine.
Journal Bearings:
The crankshaft features multiple journal bearings that support the connecting rods. These bearings reduce friction, ensuring that the engine operates smoothly and efficiently. Proper lubrication is essential to prevent premature wear of these bearings.
Crankpin Diameter:
The diameter of the crankpins on the Mitsubishi crankshaft is carefully engineered to withstand the load imposed by the pistons.
This dimension is critical for the engine's reliability and longevity.
Keyway and Timing Marks:
Crankshafts are precisely machined to include keyways and timing marks. Keyways are used for secure attachment to other engine components, while timing marks aid in setting the engine's timing correctly.
Heat Treatment:
To enhance the strength and durability of the crankshaft, it undergoes heat treatment processes such as quenching and tempering. These processes improve the material's properties and resistance to fatigue.
Corrosion Resistance:
The crankshaft is coated with anti-corrosion materials to protect it from environmental factors, moisture, and other potential sources of corrosion. This ensures a longer lifespan for the engine.
Compatibility:
The Mitsubishi crankshaft for S4F, S4K, and S6K engines is manufactured to precise OEM specifications, ensuring easy installation and compatibility with these engine models.
