Engineered for the CAT 3500 engine family, the Caterpillar 250-1311 fuel injector is a high-pressure diesel injection component designed for 3512B series engines and compatible with 3512C, 3516, 3516B, 3516C, and 3508 configurations. Installed in the cylinder head, this injector delivers accurate fuel metering and fine atomization, directly supporting combustion quality, power output, and fuel economy. It serves generator drive, marine propulsion, mining, oil & gas, and industrial power unit applications, from data center backup generators to offshore platforms and heavy-duty construction machinery.
Every unit is built to OEM engineering standards using CNC-machined components held to micron-level tolerances. Multi-hole nozzle technology improves fuel atomization and combustion uniformity, while the high-pressure fuel delivery design maintains stable performance under extreme injection pressures. Critical internal parts receive specialized heat treatment for wear resistance, and corrosion-resistant materials make the injector suitable for marine and offshore environments. The optimized spray pattern reduces fuel consumption, extends service life across thousands of operating hours, and improves transient load response in both prime and standby power operations.
Supplied as a new replacement injector, part number 250-1311 (2501311) cross references 10R0957, 10R0958, 10R0960, 190-4976, and 236-3271, simplifying sourcing for distributors, engine rebuilders, and maintenance contractors. Backed by a 12-month warranty, it offers a dependable solution for CAT 3512B fuel system maintenance and overhaul programs.
