Caterpillar original 272-0630 Fuel Injector for Construction Machinery, for heavy duty diesel engine application, Replacement OEM 374-0750, 276-8307, Cross Reference 10R-1273 original new injector

The Caterpillar 272-0630 Fuel Injector is a precision-engineered, high-pressure diesel injector designed for CAT C15 ACERT engines. As a critical component of the electronic fuel injection system, it delivers accurate fuel atomization, optimized combustion efficiency, reduced emissions, and dependable performance under heavy-duty conditions. It is compatible with C15 MXS, NXS, BXS, SDP, MBN, and KCB engine variants, with cross references including 10R1273, 10R7225, 20R2057, 20R8064, 2352888, 2360962, 2490713, 2638218, 3282574, and 3282575. Compatibility should be verified against the engine serial number (ESN) before ordering.

Operating within Caterpillar's Electronic Unit Injection (EUI) system, the injector receives commands from the electronic control module (ECM), which calculates precise fuel quantity before the solenoid valve actuates the internal plunger, delivering high-pressure atomized fuel into the combustion chamber. This optimized spray pattern ensures precise fuel metering, improved horsepower output, reduced smoke emissions, better cold-start performance, and enhanced fuel economy. Built to OEM-grade standards, the injector features long-life hardened components, corrosion-resistant construction, and factory flow testing on every unit.

The 272-0630 serves Peterbilt, Kenworth, and Freightliner trucks, plus CAT construction equipment, mining machinery, power generation systems, marine engines, and oil & gas power applications. It is distributed across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia. With a minimum order of one piece, monthly capacity of 10,000 pieces, and 3–15 day delivery, every unit is 100% tested before shipment and backed by a 12-month warranty with global shipping.
