Air Filter (空气滤清器, Воздушный фильтр): Cleans the intake air to prevent dust and debris from entering the engine. A vital component in all engineering machinery.
Hydraulic Cylinder (液压缸, Гидравлический цилиндр): Converts hydraulic power into linear mechanical motion, used in the boom, arm, and bucket of excavators like the Hitachi EX135.
Radiator (散热器, Радиатор): Cools the engine coolant, preventing the engine from overheating. Found in most heavy machinery, including XCMG XE35U excavators.
Track Roller (支重轮, Опорный каток): Supports the weight of the excavator and allows the tracks to move smoothly. Used in tracked excavators and bulldozers like the Shantui SD32.
Turbocharger (涡轮增压器, Турбокомпрессор): Increases the power of the engine by forcing more air into the combustion chamber. Often found in high-performance diesel engines in machines like the Perkins 403-11.
Slew Motor (回转马达, Поворотный двигатель): Rotates the upper structure of the excavator, allowing it to swing. A key component in excavators like the Komatsu PC1250LC-10.
