10R-1306 fuel injector is a heavy-duty, precision-engineered electromagnetic diesel injector developed specifically for c-aterpillar 3126, 3116, and 3114 industrial diesel engines, serving as a high-grade OEM-equivalent replacement to revive full engine power, enhance fuel combustion efficiency, and meet strict global heavy-duty equipment emission standards. Unlike standard aftermarket injectors, this unit is built with reinforced high-strength heat-resistant alloy steel for the main body and ultra-fine precision machined internal components, including laser-calibrated spray nozzles, high-temp sealing rings and heavy-duty solenoid valves, making it specially adapted to withstand extreme high-pressure fuel systems, prolonged high-temperature operation, and the harsh dust, vibration and heavy-load conditions found in construction, mining, marine auxiliary and agricultural heavy machinery.
