Glossary of Common Machinery Parts

• Excavator Bucket (挖掘机铲斗): Attached to the excavator's arm (dipper stick), used for digging, scooping, and loading materials like soil, rock, and debris.
  Example (实例): Caterpillar CAT 336 Excavator Bucket (卡特彼勒 CAT 336 挖掘机铲斗)

• Turbocharger (涡轮增压器): A forced induction device, typically on diesel engines, that uses exhaust gases to spin a turbine, which drives a compressor to force more air into the engine cylinders, increasing power and efficiency. Located on the engine's exhaust manifold system.
  Example (实例): Komatsu PC200-8 Turbocharger (小松 PC200-8 涡轮增压器)

• Hydraulic Pump (液压泵): The heart of the hydraulic system, converting mechanical energy into hydraulic energy (fluid flow and pressure) to power cylinders, motors, and other actuators. Usually driven by the engine.
  Example (实例): John Deere 6155M Hydraulic Pump (约翰迪尔 6155M 液压泵)

• Fuel Injector (喷油器): Delivers precisely metered amounts of fuel into the engine's combustion chamber or intake manifold under high pressure. Located in the cylinder head or intake manifold.
  Example (实例): Volvo D13 Engine Fuel Injector (沃尔沃 D13 发动机喷油器)

• Radiator (散热器): A heat exchanger used to cool the engine coolant. Located at the front of the vehicle or machine, where it can receive airflow.
  Example (实例): Scania R450 Truck Radiator (斯堪尼亚 R450 卡车散热器)

• Alternator (交流发电机): Generates electrical power to charge the battery and run the vehicle's electrical systems while the engine is running. Typically belt-driven by the engine.
  Example (实例): Ford F-150 Alternator (福特 F-150 交流发电机)

• Brake Pad (刹车片): A component of disc brakes that applies friction to the brake disc (rotor) to slow or stop the vehicle. Located within the brake caliper.
  Example (实例): Toyota Camry Brake Pad (丰田凯美瑞刹车片)

• Air Filter (空气滤清器): Removes dust, pollen, and other particulate matter from the air entering the engine's intake system, protecting internal engine components. Located in the engine's air intake system.
  Example (实例): Case IH Magnum 340 Tractor Air Filter (凯斯 IH Magnum 340 拖拉机空气滤清器)

• Piston (活塞): A component within the engine cylinder that moves up and down, transferring force from expanding gas during combustion to the crankshaft via a connecting rod. Located inside the engine cylinders.
  Example (实例): Cummins ISX Engine Piston (康明斯 ISX 发动机活塞)

• Final Drive (终传动): The last gear reduction component in a powertrain, transmitting power to the wheels or tracks while increasing torque. Located near the driving wheels or sprockets.
  Example (实例): Caterpillar D8T Dozer Final Drive (卡特彼勒 D8T 推土机终传动)
