The Cummins 3053124-20 is a PT (Pressure-Time) type fuel injector designed for Cummins heavy-duty diesel engines utilizing the PT fuel system. It features mechanical metering and hydraulic actuation driven by the engine camshaft. This injector is engineered for high-pressure fuel delivery in severe duty cycles typical of mining, power generation, and heavy construction equipment. The -20 suffix denotes a specific calibration variant commonly referenced in KTA38-G2A generator set parts catalogs. Remanufactured versions (R-3053124, 3053124PX) are calibrated to meet OEM flow and spray pattern specifications.
