Built for the Caterpillar C15 engine platform, the CAT 10R-1273 fuel injector is a precision-engineered diesel injection component manufactured to strict OE specifications. Operating within the Electronic Unit Injection (EUI) system, it delivers accurate fuel metering and optimized atomization under demanding heavy-duty conditions. The injector is widely applied across construction, mining, transportation, marine, oil & gas, and power generation sectors, serving highway trucks, mining trucks, wheel loaders, excavators, generator sets, marine vessels, and oilfield equipment.

During operation, the Electronic Control Module (ECM) calculates fuel demand and signals the injector solenoid; the plunger then pressurizes fuel inside the injector chamber until the nozzle needle lifts and fuel atomizes into the combustion chamber. This precisely controlled sequence supports reduced fuel consumption, improved combustion efficiency, lower exhaust emissions, enhanced power output, and extended engine life, helping operators maintain engine efficiency, fuel economy, and emissions compliance.

Engineered for durability, the 10R-1273 combines a precision nozzle design for superior atomization, hardened wear-resistant components, corrosion-resistant materials, and high-pressure fuel delivery capability, all calibrated to OEM specifications. Every unit is 100% tested before shipment and meets OEM-equivalent quality standards, with new and remanufactured options available. Cross-referenced with 10R-1273/10R1273, 249-0713/2490713, and 20R-8063/20R8063, it is backed by a 12-month warranty, neutral or customized OEM packaging, technical support, and worldwide shipping.
