Remanufactured Engines Superior to Used Generators
Remanufactured Engines Unlike Used Generators
When selecting industrial power generation equipment,
many people consider used generators as a way to reduce costs.
However, compared to typical used generators,
remanufactured engines offer significant advantages.
These benefits are not only reflected in performance and lifespan
but also in reliability and environmental sustainability.
A remanufactured engine is a product that has been fully disassembled,
cleaned, tested, repaired, and had worn parts replaced
according to the original manufacturer’s specifications by a professional factory.
This process ensures that each engine’s performance is nearly on par
with new products and undergoes rigorous testing to ensure stable operation.
In contrast, typical used generators are often resold
without detailed repairs or performance restoration,
which can lead to issues such as low efficiency
or frequent breakdowns during actual operation.
With high traceability and comprehensive after-sales service support,
users can confidently monitor the equipment’s status
and receive better technical assistance.
From a sustainability perspective,
remanufacturing aligns with the principles of the circular economy.
By extending product lifespan and reducing resource waste,
it helps businesses achieve their ESG (Environmental, Social, and Governance) goals.
For businesses that prioritize stable operations and long-term economic benefits,
remanufactured engines are undoubtedly
a superior choice compared to traditional used generators.
Remanufactured Engine Processing Flow
1.Repair Methods
(1) Each used engine first enters the sandblasting chamber for paint removal, followed by a thorough disassembly.
(2)The cylinder block and all components are cleaned and restored using a high-temperature, high-pressure water jet, removing all dirt from the water and oil passages. After cleaning, the internal parts are like new.
(3) All components undergo professional inspection according to original factory standards, with all worn parts replaced by imported components from the U.S.
(4) Once all inspections are completed, the engine assembly begins. After assembly, the engine undergoes load testing and inspection on a test bench. Finally, the product is completed using automotive spray painting techniques.
2.Parts Replacement
The following items are completely replaced with brand new parts:
※Piston Rings (USA FP)
※Cylinder Liner (USA FP)
※Valves (USA FP)
※Crankshaft Bearing (USA FP)
※Connecting Rod Bearing (USA FP)
※Turbocharger Assembly (USA Holset)
※Repair Kit (USA FP)
※Turbocharger Inlet and Return Oil Pipes
※External Bolts
※Hose Clamps
※Peripheral Accessories and Consumables
3.Product Standards
(1) Remanufactured by Cummins USA, not Cummins Chongqing, ensuring more stable and reliable quality and performance.
(2) The engine starts at room temperature without emitting white smoke, and the frequency remains stable.
(3) The engine operates without emitting black smoke under 90% or higher load.
(4) The engine oil pressure remains above 4 bars, and the water temperature stays around 80°C.
(5) After 100 hours of engine operation, the lubricating oil will not turn black.
The engine undergoes sandblasting before being thoroughly disassembled.
After cleaning and inspection, the engine is assembled into a finished product.
