Component Glossary & Troubleshooting

We believe in empowering our customers with knowledge. Here are some key component definitions and a common troubleshooting scenario:

Parts Definitions:

• Turbocharger (涡轮增压器) : A device that uses exhaust gas to spin a turbine, which in turn compresses the intake air, forcing more air into the engine to increase power output. Example: Volvo EC210D turbocharger (沃尔沃 EC210D 涡轮增压器, турбокомпрессор Volvo EC210D).
• Gasket (垫片) : A mechanical seal that fills the space between two or more surfaces, generally to prevent leakage from or into the joined objects while under compression. Example: Volvo D12D valve cover gasket (沃尔沃 D12D 气门室盖垫, прокладка крышки клапана Volvo D12D).
• Injector (喷油器) : A valve that sprays fuel into the engine's combustion chamber. Example: Volvo EC210D injector (沃尔沃 EC210D 喷油器, инжектор Volvo EC210D).
• Sensor (传感器) : A device that detects and responds to some type of input from the physical environment. Example: Volvo EC290B atmospheric pressure sensor (沃尔沃 EC290B 大气压力传感器, датчик атмосферного давления Volvo EC290B).
• Water Pump (水泵) : A pump used to circulate coolant from the radiator to the engine's water jacket. Example: Volvo D8K water pump (沃尔沃 D8K 水泵, водяной насос Volvo D8K).
• Alternator (发电机) : A generator that produces an alternating current, which is converted to direct current to charge the battery and power electrical systems. Example: Volvo TAD1150VE alternator (沃尔沃 TAD1150VE 发电机, генератор Volvo TAD1150VE).
• Crankshaft Rear Oil Seal (曲轴后油封) : A seal located at the rear of the crankshaft to prevent oil leakage from the engine. Example: Volvo EC290B crankshaft rear oil seal (沃尔沃 EC290B 曲轴后油封, заднее сальник коленчатого вала Volvo EC290B).
• Hydraulic Pump (液压泵) : A device that converts mechanical power into hydraulic energy, used to power cylinders and motors in heavy equipment. Example: Volvo EC460 hydraulic pump repair kit (沃尔沃 EC460 液压泵修理包, комплект для ремонта гидравлического насоса Volvo EC460).
• Piston Pin (活塞销) : A hollow, steel shaft that connects the piston to the connecting rod. Example: Volvo EC350DL piston pin (沃尔沃 EC350DL 活塞销, поршневой палец Volvo EC350DL).
• Starter Motor (启动马达) : An electric motor used to crank the engine to start its operation. Example: Volvo EC460 starter motor (沃尔沃 EC460 启动马达, стартер Volvo EC460).

Common Troubleshooting:

Problem: The Volvo EC200B D6E excavator suddenly loses power and the engine runs rough, sometimes with black smoke from the exhaust.

Possible Cause & Solution: This could be a sign of a clogged or failing fuel filter element (燃油滤芯) or a malfunctioning injector (喷油器) . First, check the fuel filter (part no. VOE20805349) and replace it if it's dirty. If the problem persists, an injector (part no. 0445120067) may be faulty. Inspect the injectors for leaks or signs of wear, or have them tested by a professional. This issue can be prevented with regular maintenance and using high-quality diesel filter elements and fuel system cleaners .
