Construction engine components include critical parts such as pistons, rings, crankshafts, connecting rods, and cylinder heads that ensure the performance of heavy-duty diesel engines. These parts are engineered for extreme loads and are commonly made from hardened steel alloys, high-graphite cast iron, and die-cast aluminum. Piston ring diameters range from 95 to 125 millimeters, with hardness ratings up to 220 HB. The crankshaft is produced with nitriding treatment and withstands torques exceeding 3000 Newton-meters. Connecting rods are forged steel with a tensile strength of about 850 MPa, ensuring long service life under harsh working conditions.
Engine components in construction machinery not only require high strength but also exceptional wear and heat resistance. Valves are manufactured from alloy steel capable of withstanding up to 780 degrees Celsius, while bearings are reinforced with babbitt or bronze layers. Precise lubrication is provided by an oil pump system operating at 4 to 6 bar pressure, reducing frictional heat. The expected service life of these parts ranges from 7000 to 10000 hours, depending on application. Surface coatings such as phosphate or molybdenum applied on rings and pistons minimize wear and enhance overall engine efficiency.

Construction engine components include assemblies such as pistons, rings, bearings, camshafts, and cylinder heads, all designed for optimal performance in diesel engines. These parts operate under extreme conditions with combustion pressures above 160 bar and speeds up to 2200 RPM. Pistons are manufactured from forged aluminum with heat resistance up to 400 degrees Celsius, while rings are made of alloyed cast iron with high wear resistance. Crankshafts are produced through forging and surface hardening processes, capable of withstanding heavy bending and torsional stresses.
To ensure durability, bearings are reinforced with babbitt or tin alloys and can withstand loads exceeding 6000 Newtons per square centimeter. Valves are made of heat-resistant steel and remain stable under temperatures of 800 degrees Celsius. The lubrication system operates at 5 bar oil pressure to minimize frictional heat and extend service life. With proper maintenance, the expected lifetime of construction engine components ranges between 8000 and 12000 hours, reflecting the importance of precise engineering and high-quality materials in this field.
