Caterpillar original For Caterpillar C9 Engine, Fuel Injector 267-9722, Common Rail Fuel Injector, Cross Reference 293-4071, for 330D 336D Excavator, Replacement for OEM original new injector

Precision-engineered for Caterpillar C9 diesel engine platforms, the 267-9722 HEUI electronic unit injector is an original OEM-grade fuel system component built to meet strict Caterpillar performance specifications. It carries primary OE number 267-9722 (alternate formatting: 2679722) and is cross-referenced to both standard service part numbers and Caterpillar remanufactured part numbers, enabling flexible parts sourcing for maintenance, repair, and overhaul operations. The injector is compatible with all C9 engine variants, including ACERT, industrial, generator, and marine configurations.

Leveraging Caterpillar’s proven HEUI architecture, the injector uses high-pressure engine oil to intensify fuel pressure before injection. Guided by signals from the engine’s electronic control module, its solenoid activates to drive an intensifier piston, raising fuel pressure to calibrated levels before the nozzle opens to release finely atomized fuel into the combustion chamber. This design delivers precise fuel metering, improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, and consistent power output for demanding workloads.

Built to withstand harsh heavy-duty operating conditions, the unit fits a broad range of Caterpillar equipment including 330D/336D excavators, 950H/966H/972H wheel loaders, 140M/160M, 725/730 off-highway trucks, C9 generator sets, and industrial power units. It serves 10 core industrial sectors and comes with a 12-month warranty for B2B fleet operators, maintenance providers, and aftermarket customers.
