For industrial parts distributors, fleet maintenance teams and heavy equipment operators sourcing reliable, specification-compliant fuel system components, the Caterpillar 10R-7224 is an original OEM diesel injector purpose-built for CAT C9 and C9 ACERT 8.8L diesel engine platforms. Manufactured to meet strict Caterpillar OEM performance and durability specifications, it supports cross-reference matching with 12 industry-recognized part numbers to streamline global aftermarket and remanufacturing supply chains.

Integrated into the engine’s electronic fuel injection system, the 10R-7224 uses ECM-controlled solenoid actuation to deliver precisely metered, optimally atomized fuel directly into the combustion chamber. This calibrated fuel delivery delivers measurable operational benefits: improved fuel economy, reduced exhaust emissions, stable idle performance, lower overall fuel consumption, higher engine efficiency, and extended service life under harsh heavy-duty operating conditions.

The injector is compatible with a broad range of CAT equipment across construction, mining, marine, power generation, oil and gas, and heavy-duty transportation sectors, including excavators, wheel loaders, dozers, articulated trucks, generator sets, marine engines, industrial power units and oilfield equipment. It comes with a 12-month warranty, and installation per official Caterpillar service procedures is recommended to maximize long-term performance and service life.
