Engineered for heavy-duty diesel performance, the 10R-7221 fuel injector is a precision-manufactured component built to meet the demanding operational requirements of the C7 ACERT engine family. Cross-referenced with OE numbers 249-0713 and 328-2585, this injector assembly delivers OEM-level reliability across construction, mining, agricultural, marine, and power generation applications. Each unit is produced through high-precision machining processes to ensure dimensional accuracy, sealing integrity, and consistent long-term operation under high-pressure common rail conditions.
This injector features advanced fuel atomization technology that improves combustion efficiency, reduces particulate emissions, and enhances overall engine responsiveness. Precise fuel metering ensures stable fuel delivery across the entire load range, resulting in lower fuel consumption and smoother engine operation. Corrosion resistance and high temperature resistance extend the service life of the injector, making it a dependable choice for commercial trucks, city buses, excavators, generator sets, and industrial power units operating in harsh environments.
Common failure symptoms such as white smoke, black smoke, engine knock, fuel odor, reduced power, increased emissions, or ECM fault codes indicate the need for injector replacement. To maximize service life, use ultra-clean diesel fuel, replace fuel filters regularly, avoid water contamination, perform injector balance testing, monitor fuel pressure, and follow scheduled maintenance procedures. The 10R-7221 is the trusted OE replacement for professional fleet and equipment operators worldwide.
