Bosch original For GE13 Series Engine Common Rail Fuel Injector Assembly 109962-0021, for heavy duty diesel engine application, 109962-0020 for Diesel Applications original new injector

The BOSCH GE13 Fuel Injector 109962-0021 is an OEM-standard diesel fuel injection component built for demanding industrial heavy-duty operating conditions. As a precision fuel metering device, it follows a calibrated injection process: high-pressure fuel lifts the internal needle valve at the specified threshold, atomizes through precision nozzle holes, and enters the combustion chamber to support complete, efficient combustion. This design delivers stable combustion performance, improved fuel economy, reduced particulate emissions, lower component wear, and extended engine service life.
Listed across global OEM, remanufactured, aftermarket, and distributor component databases, the injector supports multiple interchangeable part numbers to simplify parts sourcing and replacement. It fits a wide range of diesel engine categories including industrial heavy-duty, generator, mining, construction, agricultural machinery, marine auxiliary, stationary power, industrial compressor, and oil & gas engines, with compatible equipment covering generator sets, excavators, wheel loaders, bulldozers, agricultural tractors, road construction machinery, mining equipment, and marine auxiliary power systems.
Engineered for industrial-grade reliability, it features corrosion resistance, high-pressure operation capability, precision fuel atomization, and low maintenance costs to cut total operating expenses for equipment operators. Standardized installation requires injector seat cleaning, new copper sealing washers, calibrated torque application, fuel pressure verification, and leak testing, while routine maintenance relies on clean diesel fuel, regular filter changes, and water contamination prevention to preserve spray quality. It is a genuine OEM replacement solution serving industrial power, construction, mining, agricultural, oil & gas, and marine sectors worldwide.
