Engineering & Vehicle Parts Glossary

• Fuel Injector (喷油器): Delivers fuel into the engine cylinders. Location: Engine combustion system. Example: John Deere 6430 Fuel Injector (约翰迪尔 6430 喷油器).

• Radiator (散热器): Dissipates heat from the engine coolant. Location: Vehicle cooling system, typically at the front. Example: Volvo FH Radiator (沃尔沃 FH 散热器).

• Turbocharger (涡轮增压器): Uses exhaust gases to spin a turbine, forcing more air into the engine for increased power. Location: Engine exhaust and intake system. Example: Cummins ISX15 Turbocharger (康明斯 ISX15 涡轮增压器).

• Hydraulic Pump (液压泵): Converts mechanical energy into hydraulic energy to power hydraulic systems. Location: Hydraulic system, driven by engine or motor. Example: Caterpillar CAT 320D Hydraulic Pump (卡特彼勒 CAT 320D 液压泵).

• Steering Gearbox (转向机): Converts the rotary motion of the steering wheel into linear motion to turn the wheels. Location: Vehicle steering system, connected to steering column and linkage. Example: Mercedes-Benz Actros Steering Gearbox (梅赛德斯-奔驰 Actros 转向机).

• Brake Caliper (制动卡钳): Houses brake pads and pistons that squeeze against the brake rotor to slow down the vehicle. Location: Attached to wheel hub, enclosing the brake rotor. Example: Scania R Series Brake Caliper (斯堪尼亚 R 系列 制动卡钳).

• Drive Shaft (传动轴): Transmits torque from the transmission to the differential (or directly to wheels). Location: Drivetrain, typically underneath the vehicle connecting transmission to axles. Example: Komatsu PC200-8 Drive Shaft (小松 PC200-8 传动轴).

• Air Filter (空气滤清器): Removes dust and debris from the air entering the engine. Location: Engine intake system. Example: JCB 3CX Air Filter (杰西博 3CX 空气滤清器).

• Alternator (发电机): Generates electrical power to charge the battery and run electrical systems while the engine is running. Location: Engine bay, driven by a belt. Example: Case IH Magnum Alternator (凯斯纽荷兰 Magnum 发电机).

• Track Chain (履带链条): The linked metal segments forming the tracks on tracked vehicles. Location: Vehicle undercarriage. Example: Kobelco SK210 Track Chain (神钢 SK210 履带链条).
