Optimizing Performance with C240-4 Piston and Rings

The Isuzu C240-4 Piston (5-12111-203-0) is engineered for the specific demands of the C240-4 engine, ensuring perfect combustion sealing and efficient power delivery, vital for consistent output from a Diesel Generator.

The corresponding Piston Ring Set (5-12181-027-0) is critical for maintaining high compression and effective oil control. These robust Piston Rings minimize blow-by and oil consumption, extending the service life of the cylinder liner and reducing maintenance costs.

As a leading Engine Parts Exporter, we guarantee that our entire range of components, from fuel injectors to water pumps, adheres to the highest quality standards for reliable global supply.

Engineering Machinery Parts Glossary: Location and Application

Key engine components, their location, and specific equipment examples:

1. Cylinder Liner: Inserted into the Engine Block Bore. Forms the inner wall of the cylinder. Caterpillar D5K C4.4 Cylinder Liner.

2. Fuel Pump (Diesel Pump): Mounted on the Engine Block. Pressurizes and delivers fuel to the injectors. Cummins 6BT 5.9 Fuel Pump.

3. Connecting Rod Bearing: Sits inside the Connecting Rod's Big End. Cushions the connection to the crankshaft journal. Komatsu PC200-8 6D107E Connecting Rod Bearing.

4. Thrust Washer: Located on the Main Bearing Cap. Prevents excessive axial movement of the crankshaft. Isuzu 4BG1 Thrust Washer Set.

5. Oil Pump: Located in the Oil Pan or Engine Block. Circulates lubricating oil under pressure. Kubota V2403 Oil Pump.

6. Turbocharger: Attached to the Exhaust Manifold. Boosts the pressure of air entering the engine. Yanmar 4TNV98 Turbocharger.

7. Cylinder Head Gasket: Seals the interface between the Cylinder Head and Engine Block. Weichai WP10 Cylinder Head Gasket.

8. Main Bearing (Crankshaft Bearing): Supports the Crankshaft within the engine block. Caterpillar 3306 Main Bearing.

9. Water Pump: Mounted on the Engine Block. Circulates coolant for temperature control. Cummins QSL9 Water Pump.

10. Connecting Rod: Connects the Piston to the Crankshaft. Transfers force from combustion. Komatsu PC30 SAA4D95LE-5 Connecting Rod.

Engine Fault Diagnosis: Caterpillar 320D Excavator

Fault: Caterpillar 320D (Engine: C6.4) Excessive Engine Vibration at Idle.

Cause Analysis: Excessive vibration, particularly at low engine speeds, often points to an issue with rotational balance or a misfire. Potential causes include a failed Fuel Injector (causing uneven cylinder power), a problem with the Crankshaft Bearing/damper, or a severe compression loss in one cylinder due to a broken Piston Ring.

Specific Solution: For the Caterpillar C6.4 engine, a cylinder cutout test should be performed using diagnostic tools to isolate the misfiring cylinder. If a cylinder is found to be dead, check the compression. If compression is low, it indicates an issue with the Piston, Piston Rings, or valve train. If compression is good, the Fuel Injector for that cylinder should be replaced. If the vibration persists across all cylinders, inspect the Crankshaft's main bearings and the condition of the engine's external dampers and mounts to ensure proper rotational balance.
