Construction Machinery Engine Parts

Engine parts of construction machinery from Komatsu, Hyundai, and Caterpillar include pistons, crankshafts, bearings, rings, and valves designed for reliable operation of heavy-duty diesel engines. These components operate under combustion pressures exceeding 150 bar and working temperatures between 90 and 110 degrees Celsius. Pistons are manufactured from forged aluminum alloys with heat resistance up to 400 degrees, while rings are made from alloyed cast iron with hardness around 230 HB. Crankshafts undergo surface hardening to achieve 58–62 HRC and withstand high torque values ranging from 2800 to 3200 Newton-meters.

Valves are produced from heat-resistant alloy steel and can operate under temperatures up to 750 degrees Celsius. Bearings are reinforced with babbitt or bronze alloys, allowing them to withstand loads of 6000 Newtons per square centimeter. The lubrication system functions at an oil pressure of 4 to 6 bar to minimize friction and reduce thermal stress. The estimated service life of these engine components in Komatsu, Hyundai, and Caterpillar construction machinery ranges between 9000 and 12000 hours under standard conditions.
