original 242-0857 Rail Fuel Injector Assembly 293-4072 254-4340 267-3360 for 330D 336D C9 Engine new injector original new injector

The C9 fuel injector 242-0857 is a high-performance diesel injection component purpose-built for C9 engine platforms, including C9 ACERT, C9 Industrial, C9 Marine, C9 Generator Set, and the 330D and 336D engine configurations. Designed in strict accordance with OEM specifications, this injector serves as a direct-fit replacement that restores factory-level fuel delivery characteristics without requiring modification. Extensive cross-reference compatibility with part numbers such as CA2420857, 10R-9002, 10R-4764, 10R-7221, 10R-7222, and 10R-7223 ensures seamless integration across a wide range of C9 applications, simplifying parts sourcing for fleet operators and service facilities.

Engineered as a precision high-pressure fuel metering device, the 242-0857 injector utilizes electronic control signals to determine precise injection timing, while micro-machined nozzle holes deliver ultra-fine atomization for optimized combustion efficiency. Constructed from high strength alloy steel, this HEUI injector provides accurate fuel metering, reduced fuel consumption, lower exhaust emissions, and enhanced overall engine reliability. The combination of robust material selection and precision manufacturing results in consistent performance under the demanding duty cycles typical of C9 operations.

The 242-0857 fuel injector is validated for deployment across construction, mining, oil and gas, marine, agriculture, and power generation applications, supporting excavators, loaders, mining trucks, pump units, workboats, large tractors, and diesel generator systems.
