In the management of long-haul logistics fleets, engine fuel consumption represents the largest single expense in operating costs. An older engine with high fuel consumption will struggle to return to optimal fuel efficiency if only partial repairs are performed.
To address the structural deterioration of the ISX 12L engine, Keluo performs a comprehensive remanufacturing process. The engine is completely disassembled into individual components; the cylinder block is rebored to restore dimensional accuracy; and injectors with poor atomization and worn high-pressure components are all replaced with new parts of OEM quality. The assembly process strictly adheres to Cummins’ original torque and clearance standards, and the electronic control modules are recalibrated to restore the fuel injection strategy to its designed state, thereby recovering the engine’s original combustion efficiency and power output levels. Every remanufactured engine undergoes full-load power verification on a dedicated test bench and is only released from the factory after key indicators—including oil pressure, exhaust temperature, and fuel consumption—meet the required standards.
In the day-to-day operations of long-haul logistics, the Keluo Rebuild ISX 12L engine delivers dual benefits. On the one hand, fuel consumption returns to normal levels; compared to continuing to use an aging engine, it reduces fuel consumption by a certain percentage per 100 kilometers, resulting in significant annual savings on fuel costs. On the other hand, a complete systematic overhaul means the equipment does not require frequent shop visits for maintenance, thereby reducing operational losses and repair costs caused by downtime due to breakdowns.
Keluo has been deeply involved in the construction machinery power sector for many years, specializing in the remanufacturing of Cummins engines, and has developed mature technical solutions for the Rebuild Engine ISX 12L model. The company operates its own large spare parts warehouse, maintaining a year-round stock of genuine-quality components to ensure controllability throughout the remanufacturing cycle. Keluo maintains a stock of multiple Rebuild engine ISX 12L units, enabling rapid delivery. The engine interfaces are fully compatible with the original equipment; the intake manifold, turbocharger connections, flywheel housing, and mounting points require no modifications, allowing for immediate installation and use. All refurbished products come with a written warranty, offering free repairs for non-human-caused damage during the warranty period. Our after-sales team provides remote guidance or on-site support to ensure equipment is quickly returned to operation.
