The Caterpillar 20R-1264 electronic fuel injector is engineered for CAT 3512B, 3508B, and 3516B diesel engines used across demanding industrial sectors. Built to original equipment calibration standards, this unit injector integrates high-pressure spray technology with wear-resistant and corrosion-resistant materials to deliver reliable performance in continuous-duty operations including marine propulsion, generator sets, mining machinery, and oil & gas installations.
The injector performs four critical functions within the electronically controlled fuel system. The ECM-regulated fuel metering circuit ensures precise delivery volume, while the precision nozzle produces fine atomization for complete combustion. Electronic ECM signal activation controls accurate injection timing, and the optimized spray pattern contributes directly to improved fuel efficiency and reduced exhaust emissions across the operating range.
Routine inspection and scheduled maintenance help maximize service life. Daily visual checks for fuel leaks, monitoring of idle smoothness, and exhaust smoke observation allow early detection of injector wear or atomization issues such as hard starting, black smoke, white smoke, rough idle, or elevated fuel consumption. Following the recommended service schedule—including fuel filter replacement, flow rate balancing, return line cleanliness checks, fuel pressure verification, and ECM diagnostic review—keeps the 20R-1264 operating within OEM specifications.
