Piston for Komatsu 4D92

The piston 6140-31-2010 functions as the moving boundary within the cylinder of the Komatsu 4D92 engine. It receives the force generated by the combustion of fuel and air, converting this energy into linear motion. This movement is transferred through the connecting rod to the crankshaft, which ultimately provides the rotational power required to operate the machinery. The component is engineered to maintain the structural integrity necessary to withstand the internal pressures and thermal loads experienced during the power stroke.

This part is compatible with the Komatsu 4D92 engine series. It is designed to accommodate the piston rings required for maintaining compression and managing oil control within the cylinder bore. Proper installation ensures that the combustion chamber remains sealed, which is necessary for the efficient conversion of fuel energy into mechanical work.

In internal combustion engines, the piston acts as the interface between the combustion gases and the mechanical drivetrain. Its reciprocating action is fundamental to the intake, compression, power, and exhaust strokes of the engine cycle. By maintaining a precise fit within the cylinder, the piston ensures that the engine operates with the intended compression ratios and power output.
