Detailed Description |
| Part number | 3007517-20 | Installation torque | The standard torque of similar products is 20-25N·m (subject to the technical manual) |
| Compatible engine | Cummins K19, QSK19 and other generator sets | Sealing requirements | The installation interface needs to be cleaned to prevent impurities from entering the oil passage and ensure the sealing property |
| Functional design | High-pressure injection of engine oil to the bottom of the piston reduces the thermal load and prevents the piston from deforming or melting | Adapt to scenarios |
1.Main applications: : construction machinery (such as excavators, loaders), heavy-duty trucks, generator sets and other high-load equipment 2.Suitable working conditions : continuous high torque output, high-temperature environments (such as mines, construction sites) |
| Pressure range | Compatible with Cummins high-pressure common rail fuel system (HPCR), the fuel injection pressure can reach up to 1600bar | Maintenance suggestions |
1.Regularly check if the nozzles are clogged or worn (it is recommended to check every 15,000 hours) 2.Use engine oil that meets cummins standards to ensure cooling effect |
Product Advantages
1. Material and Structural Advantages
High-Temperature Resistant Materials: Constructed from stainless steel or high-temperature alloys, some models feature a ceramic coating, capable of withstanding extreme temperatures from -40℃ to 300℃, effectively preventing piston thermal deformation or cap melting.
High-Pressure Compatibility: Adapted to Cummins High-Pressure Common Rail (HPCR) systems, with injection pressures up to 1600 bar, ensuring precise cooling of the piston bottom and improving cooling efficiency by over 30%.
2. Performance and Reliability
Extra-Long Lifespan: B10 lifespan exceeding 500,000 hours, significantly superior to the industry average.
Wear-Resistant Design: Optimized sealing structure reduces the risk of oil leakage; ceramic coating further reduces high-temperature wear.
Easy Maintenance: Modular design supports quick disassembly and assembly; recommended inspection every 15,000 hours.
