Caterpillar original Replacement Fuel Injector 241-3228 for C7 Diesel Engine, Cross Reference 238-8901, 241-3238, 241-3400, for Construction Machinery original new injector

For fleet operators and equipment rebuilders sourcing a dependable injection solution for the CAT C7 platform, the 241-3228 fuel injector delivers original-quality replacement performance. Designed for Caterpillar C7 and C7 ACERT diesel engines—a 7.2L inline 6-cylinder platform rated from 168 to 224 kW (225–300 hp)—this injector installs in the cylinder head, precisely controlling fuel delivery, atomization, and injection timing. It cross-references popular numbers including 10R-4763, 241-3400, 328-2585, 387-9428, 238-8091, 222-5958, and EX634763, simplifying catalog matching and procurement.

Built around Caterpillar's HEUI (Hydraulically Actuated Electronically Controlled Unit Injector) technology, the 241-3228 operates differently from conventional mechanical injectors. The engine ECM sends an injection command, the solenoid activates, and high-pressure engine oil actuates the injector plunger. Fuel pressure rises, the nozzle opens, and diesel is atomized into the combustion chamber. This electronic-hydraulic control enables precise management of injection timing, pressure, and fuel quantity—supporting stable power output and efficient combustion in demanding duty cycles.

The injector serves a broad application base: construction machinery, mining equipment, agricultural machinery, generator sets, truck and bus engines, forestry equipment, material handling, road equipment, and stationary diesel power systems. It is available as a single piece, a six-piece engine set, or in bulk wholesale quantities for distributors and rebuilders. Important: always verify compatibility by engine serial number, arrangement number, injector trim code, ECM calibration, and the original removed part number before purchase or installation.
