The CAT HEUI Injector 254-4340 is designed for C9-series engines that use the HEUI (Hydraulic Electronic Unit Injector) system. In this setup, engine oil pressure powers the injector while the ECU controls its timing electronically. This allows for very accurate fuel metering, improved atomization, and better performance under variable loads. Typical applications include excavators and heavy machinery using Cat’s C9 HEUI engines.
