The piston 6127-31-2140 serves as the primary moving component within the cylinder of the Komatsu 6D155 engine. It functions by compressing the air-fuel mixture during the intake and compression strokes and receiving the force generated by combustion during the power stroke. This force is transferred through the connecting rod to the crankshaft to produce rotational mechanical energy. The component features integrated grooves to accommodate piston rings, which maintain the seal between the combustion chamber and the crankcase to manage compression and oil regulation.
This part is compatible with the Komatsu 6D155 engine. It is engineered to meet the specific dimensional and weight requirements of this engine block to ensure proper balance and operation. Pistons in internal combustion engines must withstand the thermal and mechanical loads present during the engine cycle while maintaining a precise fit within the cylinder bore to facilitate efficient power delivery and combustion control.
