Caterpillar original 20R-2296 Common Rail Fuel Injector for 793C 793D Diesel Engine, Replacement 20R-1269 20R-0849 376-0509 375-4106 20R-3483 original new injector

The Caterpillar 3512B Fuel Injector 20R-2296 is a genuine OE replacement component engineered to deliver consistent and accurate fuel delivery across heavy duty diesel platforms. Featuring a high precision multi-hole nozzle design, this injector ensures superior atomization and complete combustion, which directly translates into optimized fuel economy and reduced exhaust emissions. Each unit is manufactured from hardened alloy steel with a specialized corrosion resistant surface treatment, providing exceptional durability and a long service life even under severe operating conditions.

Designed as a direct fit solution for CAT 3512B, 3512C, 3516B, 3516C, 3508, 3508B, 3512, 3516, and 3518 engine models, the 20R-2296 injector meets original equipment performance and dimensional specifications. It is fully interchangeable with cross reference numbers including 20R-0848, 192-2817, 150-4453, 162-8809, 162-8813, 204-2067, 229-1631, 245-8272, 246-1854, 250-1311, 423-7547, 392-0214, and 20R-0850, allowing operators to streamline inventory and simplify sourcing across multiple equipment fleets.

This injector is widely deployed in Caterpillar power generation systems, marine propulsion engines, mining haul trucks and shovels, oilfield machinery, offshore platforms, construction equipment, and stationary diesel power plants. Its high temperature resistance, wear resistant internal components, and stable calibration make it ideally suited for continuous duty industrial applications. Proper maintenance intervals, including inspection of fuel filters and injector leakage every 500 hours, spray pattern testing every 1000 hours, and comprehensive calibration verification every 2000 hours, help ensure maximum reliability and engine longevity.
