Product Detail

The crankshaft for the Mitsubishi S3L-1 and S3L-2 engines is carefully engineered to meet the demands of heavy-duty industrial applications.

It is typically a forged and machined component, crafted from high-quality steel alloys. The choice of materials is crucial to ensure durability, resistance to wear and tear, and the ability to withstand the high stresses generated within the engine. Specifications: Dimensions: The crankshaft is designed with precise dimensions to fit within the engine's crankcase and accommodate the connecting rods and pistons. It has a specific length, width, and diameter, which must be manufactured with great accuracy to ensure proper engine function. Counterweights: The crankshaft features strategically placed counterweights to balance the rotating assembly and minimize vibrations. Proper balance is crucial to ensure smooth engine operation and reduce wear on engine components. Main Journals and Rod Journals: The crankshaft is equipped with main journals and rod journals, where the main bearings and rod bearings are mounted, respectively. These journals are precisely machined to ensure proper alignment and minimize friction between the crankshaft and the bearings.

Crankshaft Throws: The number and configuration of crankshaft throws correspond to the number of cylinders in the engine.

For the S3L-1 and S3L-2 engines, which are typically three-cylinder diesel engines, the crankshaft would have three throws, each connected to a connecting rod. Oil Passages: The crankshaft includes oil passages that provide lubrication to the main and rod bearings. Adequate lubrication is essential to reduce friction and prevent premature wear of the bearings. Crankshaft Gear: In many applications, a gear is integrated into the front of the crankshaft. This gear is used to drive the timing components, such as the camshaft and fuel injection pump, ensuring precise timing of engine events. Keyways and Splines: The crankshaft may have keyways or splines to connect it to other engine components, such as the flywheel or vibration damper. Surface Finish: The surfaces of the crankshaft, particularly the journals, are finished to a high degree of smoothness. This smooth finish reduces friction and wear, contributing to the crankshaft's longevity.
