Construction Machinery Engine Parts

Engine components in construction machinery such as Komatsu, Hyundai, and Caterpillar consist of essential parts including pistons, rings, crankshafts, bearings, and cylinder heads. These parts are engineered to withstand high pressures and continuous thermal loads, ensuring stable performance of heavy-duty diesel engines. Cylinder diameters in many construction engines range from 100 to 130 millimeters, with piston strokes between 120 and 150 millimeters. Crankshafts are manufactured from forged steel with tensile strength above 900 MPa, while bearings can handle pressures up to 6500 Newtons per square centimeter.

Valves are produced from heat-resistant alloy steel capable of withstanding temperatures between 780 and 800 degrees Celsius, with surfaces hardened by chrome or nickel plating. Piston rings are coated with molybdenum to reduce friction and extend service life. The lubrication system operates at an oil pressure of 5 bar, preventing temperature rise in long-duty operations. The average service life of construction engine components is estimated at 10000 hours under standard conditions, which can be extended with regular maintenance.
