Glossary of Heavy Machinery Parts

• Turbocharger / 增压器 (Zēngyāqì)

  Installation Location: Engine exhaust system.
  Definition: A turbine-driven forced induction device that increases an internal combustion engine's power output and efficiency by forcing extra compressed air into the combustion chamber.
  Example Part:  Garrett GT2256V Turbocharger for Caterpillar 320D (Part No: 767837-5002S)

• Injector / 喷油器 (Pēnyóuqì)

  Installation Location: Engine cylinder head.
  Definition: A component of the fuel injection system that delivers fuel to the engine. In diesel engines, it directly injects fuel into the combustion chamber.
  Example Part: Bosch Fuel Injector for Volvo EC210B (Part No: 0445120081)

• Piston Ring / 活塞环 (Huósāi huán)

  Installation Location: Pistons within the engine cylinders.
  Definition: Metallic rings that fit into grooves on the piston and create a seal between the piston and cylinder wall, preventing combustion gases and oil from leaking.
  Example Part:  Piston Ring Set for Isuzu 4JB1 Engine (Part No: 8-94176-802-0)

• Crankshaft / 曲轴 (Qūzhóu)

  Installation Location: Engine block, supported by main bearings.
  Definition: A rotating shaft that converts the reciprocating motion of the pistons into rotational motion, which is then used to power the vehicle or machinery.
  Example Part:  Crankshaft for Cummins 6BT Engine (Part No: 3907804)

• Solenoid Valve / 电磁阀 (Diàncí阀)

  Installation Location: Hydraulic system, transmission, and various control systems.
  Definition: An electromechanically operated valve controlled by an electric current through a solenoid. Used to control fluid or air flow in hydraulic and pneumatic systems.
  Example Part:  Hydraulic Solenoid Valve for Komatsu PC200-8 Excavator (Part No: 20Y-60-11700)

• Gear Pump / 齿轮泵 (Chǐlún bēng)

  Installation Location: Hydraulic system, typically driven by the engine or motor.
  Definition: A type of positive displacement pump that uses gears to pump fluid. Widely used in hydraulic systems for their reliability and simplicity.
  Example Part:  Gear Pump for John Deere Tractor (Part No: RE505096)

• LS Valve (Load Sensing Valve) / 负载感应阀 (Fùzài gǎnyìng阀)

  Installation Location: Hydraulic control valve manifold.
  Definition: A type of hydraulic valve that adjusts the pump output flow and pressure according to the load requirements, improving efficiency and reducing energy consumption.
  Example Part:  LS Valve for Hitachi ZX330-3 Excavator (Part No: 9270521)

• Starter Motor Relay / 启动马达继电器 (Qǐdòng mǎdá jìdiànqì)

  Installation Location: Electrical system, often near the starter motor or in the electrical panel.
  Definition: An electromagnetic switch that controls the high current circuit to the starter motor, enabling the engine to start.
  Example Part:  Starter Relay for Komatsu PC200-7 Excavator (Part No: 206-06-61130)

• ABS Sensor / ABS传感器 (ABS chuángǎnqì)

  Installation Location: Wheel hub or axle of vehicles with ABS systems.
  Definition:  A sensor used in the Anti-lock Braking System (ABS) to monitor the wheel speed and send this information to the ABS control module to prevent wheel lock-up during braking.
  Example Part:  ABS Wheel Speed Sensor for Mercedes-Benz Actros Truck (Part No: 0025421918)

• Instrument Panel / 仪表盘 (Yíbiǎo pán)

  Installation Location: Cabin dashboard of machinery or vehicles.
  Definition: A control panel in the cabin that displays operational information to the operator, such as engine speed, temperature, pressure, and warnings.
  Example Part: Instrument Cluster/Panel for John Deere 8R Series Tractor (Part No: RE343876)
