Technical Glossary: 10 Engine Components Explained

• Cylinder Liner: The bore where the piston moves. Example: Cummins NT855 Generator Cylinder Liner 3055099.

• Piston Ring: Essential for sealing and oil control. Example: Caterpillar D6T Bulldozer Piston Ring 4089810.

• Crankshaft: Converts reciprocal motion into rotary motion. Example: Komatsu SAA6D140E-5 Dump Truck Crankshaft.

• Turbocharger: Increases engine power by compressing air. Example: Isuzu 6UZ1 Excavator Turbocharger.

• Water Pump: Circulates engine coolant. Example: Kubota V2403 Compact Loader Water Pump.

• Main Bearing: Shells supporting the crankshaft journals. Example: Yanmar 6AYM Marine Engine Main Bearing Set.

• Oil Pump: Supplies oil under pressure to the engine's moving parts. Example: Weichai WP12 Truck Engine Oil Pump.

• Thrust Washer: Manages the crankshaft's axial position. Example: Cummins QSK50 Mining Engine Thrust Washer.

• Connecting Rod: Link between the piston and crankshaft. Example: Caterpillar 3406 Dozer Connecting Rod.

• Injector: Sprays atomized fuel into the combustion space. Example: Komatsu 6D107 Engine Fuel Injector.

Engine Failure Analysis and Solution

Fault: A Cummins NT855 Generator Set experiences chronic overheating and excessive coolant pressure, sometimes leading to coolant overflow.

Resolution: Excessive coolant pressure, especially when cold or under light load, often indicates combustion gas leaking into the cooling system.

1. Head Gasket Failure: The most common source is a failed cylinder head gasket, allowing high-pressure combustion gases to enter the coolant passages.

2. Cylinder Head Crack: High thermal stress can crack the cylinder head itself, usually near the injector or valve seats, causing the same symptom.

3. Liner Protusion Check: If the failure is recurrent, check the cylinder liner protrusion (Liner 3055099) to ensure proper sealing pressure on the head gasket. Use a new, quality overhaul gasket kit and strictly follow torque procedures.
